Using the bootstrap.sh script

+

This script is prepared for a quick bootstrap of the Underpass database.

+

Install requirements

+
    +
  • fiona (pip install fiona)
    • +
  • shapely (pip install shapely)
    • +
  • osm2pgsql (https://osm2pgsql.org/doc/install.html)
    • +
  • psql (https://www.postgresql.org/download/) +
    ## Quick start
+
+Run the script passing region, country and DB username as arguments, for example:
+
+```sh
+./bootstrap.sh -r south-america -c ecuador -l yes
+
    • +
+

This will:

+
    +
  1. Delete all entries into the database (WARNING: POTENTIAL LOSS OF DATA)
    2. +
  2. Download raw data from GeoFabrik
    3. +
  3. Run osm2psql for import it
    4. +
  4. Convert the country .poly file to .geojson and install config files
    5. +
  5. Run underpass --bootstrap for bootstrapping the validation table
    6. +
+

Script options

+
-r region (Region for bootstrapping)
+   africa, asia, australia, central-america
+   europe, north-america or south-america
+-c country (Country inside the region)
+-h host (Database host)
+-u user (Database user)
+-p port (Database port)
+-d database (Database name)
+-l yes (Use local files instead of download them)
+
+

Use the -l yes when you have your .pbf and .poly files already downloaded and +you don't want to download them again. The script will look for those files +using the -r and -c arguments, for example

+
./bootstrap.sh -r south-america -c ecuador -u underpass -l yes
+
+

Will look for these files:

+
ecuador-latests.osm.pbf
+ecuador.poly
+
+

OSM authentication for downloading data

+

If you want to bootstrap your database with ChangeSet data downloaded from + GeoFabrik, you'll need to be authenticated with an OSM account.

+

A good utility for doing this from command line is in the sendfile_osm_oauth_protector + repository.

+
git clone https://github.com/geofabrik/sendfile_osm_oauth_protector.git
+cd sendfile_osm_oauth_protector
+
+

Edit settings.json with your credentials:

+

```json + { + "user": "", + "password": "", + "osm_host": "https://www.openstreetmap.org", + "consumer_url": "https://osm-internal.download.geofabrik.de/get_cookie" +} +

And download your file:
+
+```sh
+curl https://osm-internal.download.geofabrik.de/africa/tanzania-latest-internal.osm.pbf \
+   --cookie "$(cat cookie_output_file.txt)" --output tanzania-latest.osm.pbf
+

+

Then you can move the pbf file to the underpass/utils directory and use the -l yes option.

Replication Files

+

There are two types of data files related to changes in the map +data. These files contain all the changes made during a time interval, +every minute, hour, or daily data files are available from the +OpenStreetMap planet +server.

+

There are two different formats of change data, one for changesets, +and the other for the actual changes. Both are needed for filtering +changes to produce statistics.

+

Changeset

+

A changeset file contains only the data about the change, and not the +actual change itself. It contains the data of the change at the time +it's uploaded to OpenStreetMap. Each change has an action; create, +delete, modify. Each action then contains the changed objects in the +action. As this file contains the data created when uploading it to +OpenStreetMap, it's the only way to access the commit hashtags or +comments.

+

Hashtags didn’t exist until late 2014, so between 2014 and 2017, +hashtags were contained in the comment field. In 2017, the official +hashtag tag was added. The first mentions of the hashtags +#missingmaps and #hotosm starts 2017-10-20. A typical changefile +entry looks like this:

+
    <changeset id="12345" created_at="2014-10-10T01:57:09Z" closed_at="2014-10-10T01:57:23Z" open="false" user="foo" uid="54321" min_lat="-2.8042325" min_lon="29.5842812" max_lat="-2.7699398" max_lon="29.6012844" num_changes="569" comments_count="0">
+        <tag k="source" v="Bing"/>
+        <tag k="comment" v="#hotosm-task-001 #redcross #missingmaps"/>
+        <tag k="created_by" v="JOSM/1.5 (7182 en)"/>
+    </changeset>
+
+

The created_by and source fields can be used to generate +statistics of editor choices and imagery sources. Underpass uses only +the comment and hashtag fields currently as a way to group sets of +changes by organization, or mapping campaign.

+

OsmChange

+

And OsmChange file contains the data of the actual change. It uses the +same syntax as an OSM data file plus the addition of one of the three +actions. Nodes, ways, and relations can be created, deleted, or +modified. Multiple OSM object types can be in the same action. As this +data contains the actual change, it is used to filter by tag, or used +to do calculations, like the length of roads added.

+
    <modify>
+        <node id="12345" version="7" timestamp="2020-10-30T20:40:38Z" uid="111111" user="foo" changeset="93310152" lat="50.9176152" lon="-1.3751891"/>
+    </modify>
+    <delete>
+        <node id="23456" version="7" timestamp="2020-10-30T20:40:38Z" uid="22222" user="foo" changeset="93310152" lat="50.9176152" lon="-1.3751891"/>
+    </delete> 
+    <create> 
+        <node id="34567" version="1" timestamp="2020-10-30T20:15:24Z" uid="3333333" user="bar" changeset="93309184" lat="45.4303763" lon="10.9837526"/>\n 
+    </create> 
+
+

State Files

+

There are two types of state files, one for changesets and the other +for change files. The changeset one is the simplest, only containing +the last_run timestamp and a changeset sequence number. The first +state file starts 2016-09-07 10:45. An example changeset state file +is:

+
\---
+last_run: 2020-10-08 16:41:01.863533000 +00:00
+sequence: 4139643
+
+

The state file for change files contains more fields, but the only +ones needed for database updates are the timestamp of the data file, +and the sequence number. An example change file state file is:

+
#Thu Oct 08 16:38:04 UTC 2020
+sequenceNumber=4229951
+txnMaxQueried=3081409719
+txnActiveList=
+txnReadyList=
+txnMax=3081409719
+timestamp=2020-10-08T16\:38\:02Z
+
+

As the 3 digit prefix in the state filename matches the data file, +this is used to get the right data that matches that state. Since +the replication files are fetched via HTTP/HTTPS, there is no +timestamp available. To find a specific replication file, a state file +close to the timestamp is downloaded. Then the timestamp in the state +file is checked, and if it matches, the the 3 digit part of the state +file name can be used to find the appropriate replication data file.

+

Finding The Right Data File

+

It is desirable to be able to start processing changes starting with a +specific timestamp. This enables the end user to update databases +after a period of downtime. With minute updates, there are many +thousands of files. Since it takes about 10 milliseconds to download a +state.txt file from planet, scanning for files isn't really +practical. Once the proper data file is found, then it's easy to just +download the next data file in sequence.

+

Currently, the function PlanetReplicator::findRemotePath is the one +responsible for returning the file path from a timestamp. It's using +a list of of timestamps and sequence numbers stored in a local file +located in config/replicator/confiplanetreplicator.yaml for +calculating the path. This approach must be reviewed in order to +have better precision without the need of keeping that file up-to-date.

Building Packages in a Chroot

+

To distribute binary packages for a variety of platforms of varying +versions, it's common to use a chroot to build in. This is to make +sure that a the package binary is linked against the right libraries, +which is required so the user doesn't have to build anything from +source. Unlike Docker or Virtualbox, a chroot uses the base running +kernel on host machine, but provides a different set of runtime +libraries and tools.

+

Creating a Chroot

+

All platforms that use the .deb packaging format, like Debian and +Ubuntu, can use the debbootstrap program to create the +chroot. Debootstrap lets you pick the architect to support, +--arch amd64 builds files for the X86_64 platform. after that the +version of the distribution is specified, followed by the directory to +install the files in, and finally the URL to download packages +from. Once done, change to the installation directory, and type sudo +chroot .. You'll now be in a minimal runtime environment. The first +thing I do is create a /etc/debian_chroot file containing the name +of the distribution. This puts the this value into the command prompt +for the shell, which is very useful when you have multiple chroots.

+

As the chroot program requires one to be root, a utility program +called schroot can be used to fake root. Once the initial chroot is +created, change to the directory containing the downloaded files, and +type these shell commands. Some of the programs used to build packages +need these, which aren't present in the chroot, as they have to be +shared from the host platform.

+
mount -t proc proc /proc
+mount --rbind /sys sys/
+mount --rbind /dev dev/
+
+

Once that initial setup is done, it's time to download more +packages. The default config file for a chroot is limited to just the +main repository. Not all of the packages Underpass depends on are in +main, so add universe to get the rest, and then apt-get +update. Your /etc/apt/sources.list file should now look like this:

+
deb http://archive.ubuntu.com/ubuntu focal main universe
+
+

Finally edit ~/.bashrc and add these three lines at the bottom. One +specifies the path to a file pkg-config needs, but isn't always +distributed, so it's included. The other is for locale, so it stops +clutterin the terminal with warnings.

+
export PKG_CONFIG_PATH=/home/rob/underpass/m4
+export LANG=C
+export GPG_TTY="$(tty)"
+
+

To create signed packages, you need a GPG key pair setup, so might +as well do that now. Type gpg --full-generate-key, and answer the +questions. This will only work if you've execute the mount commands as +documented above.

+

+

Building Libpqxx Packages

+

The version of libpqxx (6.x) that's included in current (Aug 2021) +distribution like Debian Bullseye or Unbuntu Hirsute (21.04) has a bug triggered +by libxml++. Since Underpass uses libxml++ and libpqxx, we have to +build a package of a newer version (7.x). I added Debian packaging +files to a git repository to make this easier, Get that fork here:

+
git clone https://github.com/robsavoye/libpqxx.git
+
+

Once I do that, I run git tag, and the checkout the latest official +release branch. There's a configure bug in the libpqxx sources I +haven't gotten around to fixing yet, so I edit configure.ac, and +comment out this one line like so:

+
dnl AX_CXX_COMPILE_STDCXX_17([noext])
+
+

Then run ./autogen.sh, which produces the scripts used for +configuring. Now that you have the configure script, configure +libpqxx like this:

+
./configure CXX="ccache g++" CXXFLAGS="-std=c++17 -g -O2" --disable-dependency-tracking
+
+

After that, change to the debian directory, and type make deb -i +-k. That'll build the deb packages, and at the end, have you GPG sign +them. Once built, install the two packages, and you're all set to go +build Underpass.

+

Building Underpass Packages

+

The Underpass git repository is at:

+

https://github.com/hotosm/underpass.git

+

Once downloaded, change to the source directory and run +./autogen.sh. Once the configure files have been built, configure +Underpass like this:

+
./configure CXX="ccache g++" CXXFLAGS="-std=c++17 -g -O2" --disable-dependency-tracking
+
+

and then typing make deb -i -k builds the packages, and has you sign them.

Underpass Coding Style

+

This documents the prefered coding style for Underpass. The goal +of this coding style is to make code consistent amongst developers, +and to write code that is focused on being readable and +compact. Because the existing code is written with this goal, using +reformatting tools like indent or clang-format is discouraged.

+

The easy way to follow this style is to use +cc-mode +in Emacs. Spaces will be used instead of TABS, since different systems +or users may have TAB set differently. Indents are 4 spaces, instead +of 8.

+

Documentation

+

All code will use Doxygen style +comments. Classes and methods should each have a comment so a short +description will be displayed in the output files Doxygen +generates. Each file should also have a brief description.

+

Line Length

+

For decades lines were limited to 80 charcters or less, which was +based on what a CRT could display. With modern monitors this +limitation doesn't exist. The Linux kernel has been using 132 character +line length, so this project does too.

+

Line breaks

+

Line breaks are used to break up long lines, with the remainder +indented to be clear it's a continuation of the line. Some times a +long line is prefered if adding a line break makes the code less +readable.

+

Brace Location

+

The opening brace for most code is on the same line as the line of +code. Putting an opening brace on a line by itself adds too much +unnecessary whitespace. A closing brace is usually on a line by +itself.

+

Some examples:

+
namespace replication {
+class StateFile;
+};
+
+class RawChangeset {
+  public:
+      void foo(void);
+};
+
+

In C++ a conditional with a single line following the test is legal, +but braces should be used to make it clearer.

+
if (i == 20) {
+   // do something
+}
+
+

Naming Convention

+

Underpass uses Camel Case, +which uses capitalization instead of underbars for class definitions, +function or C++ methods, and variable. For example RawChange instead +of raw_change. Class names capitalize the first letter as well, +where the methods in the class start with a lower case letter.

+

Names should be descriptive, and when possible, avoid abbrevations +unless they are commonly used.

Underpass Data Flow

+

Flow Chart

+

The Overpass data storage contains information from several +sources. Underpass has to duplicate this collection of data and +aggregate it into a similar structure. The primary data is the map +data itself, which contains no history or change data.  All the +necessary data is available from planet.openstreetmap.org, but is not +all in the same format, and is in different places on the planet +server. There appear to be no open-source projects that aggregate all +this data together other than Overpass.

+

There are two different change file formats. One includes the hashtags +and comments from the change. The other is the changed data +itself. Both of these data files can be downloaded from the planet +server, and can also be updated with minutely changes. There is +currently no open source software that I can find to process the +changeset file, nor to merge it with the other change data. This is +one of the tasks Underpass needs to handle. To support the Missing +Maps leaderboard, and OSM Stats. the changes are used to calculate the +totals of highways, waterways, and buildings added or edited in that +change. A change it the data at uploading to OSM time. Underpass will +recreate the history as it processes the change files.

+

For producing statistics, the process initially starts by downloading +the large data file of all changes made since 2005. As hashtags didn’t +exist until late 2014, data prior to then is ignored. Starting in +2014, hashtags were stored in the comments field of the map data, till +the hashtag field was added in late 2017. This data file has some of +the fields we want, which is documented here.

+

Briefly, Underpass extracts the hashtag (if there are any) and +changeset timestamp. The next task is to download the changed data +itself. This is available at planet.openstreetmap.org as well. The +osmium program can do +this, but does not support importing it into a database. It only +works with disk files. The Replicator program will do +a similar task, namely download the changes, but will apply them to +the statistics database. While Replicator processes the changes, it +will also update the statistics database by adding the totals for the +new data to the existing amounts. For statistics collection, the +core OSM database isn't needed.

+

However the changes do need to be applied to the OSM map database, so +when processing exports, or later doing validation, it’s up to +date. The entire update process of both databases has to happen within +one minute if we want to update that frequently, which is the +goal. When updating the map database, any node or way that is changed +will be stored in the database in a new table. This will create the +history needed for augmented diffs. Only the previous version is +stored, any older entries will be deleted from the history database.

+

Source Data

+

Underpass collects data from multiple sources, primarily the +Change Files from the OpenStreetMap planet +server. Changes are availble with different time intervals. The +minutely one are the primary data source. There are two sets of +minute update, one documents the change and the other is the changed +data itself.

+

Directory Organization

+

Almost all directories and files are numerically based. The very top +level contains the +intervals, and the changeset directories, and looks like this:

+
minute/
+changeset/
+hour/
+day/
+
+

Under each one of these top level directories are the numerical +ones. At the lowest level there are 1000 files in each directory, so +the value is always a consistent 3 digit number.

+
...
+002/
+001/
+000/
+
+

Under each on of these sub-directories are the actual data ones

+
999/
+998/
+...
+001/
+000/
+
+

Each one of these directories contains 1000 files, roughly 16 hours +of data.

+
replication/002/
+replication/002/002/
+replication/002/002/002/
+replication/002/002/002/
+replication/002/002/002/002.state.txt
+replication/002/002/002/002.osm.gz
+
+

The state file contains the ending timestamp of the associated data +file. Underpass uses the state.txt file to find the right data. THe +timestamps are not a consistent time interval, so it's not really +possible to just calculate the right data file. To speed up searching +for the right data file based on a timestamp, Underpass downloads them +and enters the path to the data file and the timestamp into postgres.

+

This process works forward and backwards. When initializing a database +from scratch, Underpass will just bulk download the state files, +starting with the most recent ones, and then going backwards in +time. It takes about a week to download all the minutely state.txt +files, hourly only a few hours.

+

Underpass can also monitor for new data files, so as to keep up to +date. If the database is up to date, the threads are put to sleep, and +wake up a minute later to see if there are new files. If behind by +several minutes, Underpass will bulk download them until caught up.

+

Underpass uses simple threading, so can utilize multiple CPU +cores. When a new data file is downloaded, it's uncompressed and +parsed. During the parsing process, some data validation is done. +If a change fails validation, it's written to a database table so a +validator can look into the issue later. If it passes validation, then +statistics are calculated, and written to the database.

+

Output Databases

+

Underpass currently writes to 1 primary database: the +underpass database, which stores all the calculated statistics, data +validation results and raw OSM data that also gets updated every minute.

Development and debugging

+

Build flags

+

The following flags are suggested when running the configuration for building:

+

../configure CXX="ccache g++" CXXFLAGS="-std=c++17 -g -O0" CPPFLAGS="-DTIMING_DEBUG"

+

Debugging with GDB

+

apt-get install gdb

+

Setup an alias for gdb in your bash profile, +adding the following line add the bottom of ~/.bashrc:

+

alias lg='libtool --mode=execute gdb'

+

And you'll be able to run the debugger, for example:

+

lg src/testsuite/libunderpass.all/yaml-test +lg --args ./underpass --bootstrap

+

Debugging in MacOS

+

With GDB

+

It's also possible to debug Underpass on MacOS. You should use glibtool instead of libtool.

+

brew install gdb

+

Note that gdb requires special privileges to access Mac ports. +You will need to codesign the binary. For instructions, see: https://sourceware.org/gdb/wiki/PermissionsDarwin

+

Add the alias in your ~/.bashrc file:

+

alias lg='glibtool --mode=execute gdb'

+

With LLDB

+

When running Underpass on a MacOS system with an Arm64 architecture, gdb might be not available. +You can use lldb instead.

+

lldb -- src/testsuite/libunderpass.all/yaml-test +lldb -- .libs/underpass --bootstrap

Underpass

+

Underpass is a C++ API and utility programs for manipulating +OpenStreetMap data at the database and raw data file level. It can +download replication files from the OSM planet server and use these +files to update a local copy of the OSM database, or analyze the +changes to generate statistics. It is designed to be high +performance on modest hardware.

+

Currently this is usually done using Overpass, which can be +self-hosted or accessed remotely. Overpass has major performance +issues though, namely it’s single threaded, and doesn’t use a real +database. What Overpass does is support a wide range of querying OSM +data, and can handle rather complicated filters. Much of that +functionality is not needed for supporting statistics collection and +simple validation.

+

Underpass is designed to function as a replacement for a subset of +Overpass’s functionality. It is focused on analyzing the change data +every minute, and generating statistics or doing validation of the +metadata. It is designed to be able to process large files +by streaming the data.

+

Rather than using disk based tempfiles, it has a self-hosted database +centric design for better performance. It uses Postgresql with the +Postgis extension, both commonly used for core OSM infrastructure. One +big advantage of using postgres is it supports utilizing multi-core +processors for faster SQL queries. It can optionally use GPU +support for faster geospatial +queries.

+

The other primary design goal of Underpass is to be maintainable for +the long term. It uses common open source infrastructure to make it +accessible to community developers. The primary dependencies, which +are used by multiple other core OSM projects are these:

+
    +
  • Uses the GNU autotools for multi-platform support
    • +
  • Uses SWIG for bindings to multiple languages
    • +
  • Uses Boost for additional C++ libraries
    • +
  • Uses GDAL for reading Geospatial files
    • +
  • Uses PQXX for accessing Postgres
    • +
  • Uses Libxml++ for parsing XML files
    • +
  • Uses Doxygen for producing code documentation
    • +
+

Ideally Underpass can be used by other projects needing to do similar +tasks without Overpass. It should be able to support collecting more +statistics than are currently used. Since much of Underpass deals with +the low level data flow of OpenStreetMap, long-term it can be used to +support future projects as a common infrastructure for database +oriented mapping tasks.

+

A critical future project is conflation and validation of existing +data and mapathons. Underpass will support the database management +tasks those projects will need. The same database can also be used for +data exports, and Underpass can be used to keep that data up to +date. What the Overpass data store contains is history information, +change information, and the actual OSM data. Underpass can access this +same information by processing the change data itself.

+

Dependencies

+

Underpass requires a modern C++ compiler that supports the 2011 C++ +standard. The 2011 standard simplified the syntax by adding the auto +keyword, and thread support became part of the standard C++ +library. Underpass is a heavy user of of the boost libraries, and +also requires reasonably up to date C++ libraries for other +dependencies. Underpass also uses the ranges-v3 library. This will be +in the 2020 C++ standard, but hasn't been released yet.

+

Fedora 33, Debian Buster, and Ubuntu Groovy contain a package for +librange-v3, which is the code base for what will be in +C++ 2020. Both Debian Buster and Ubuntu Groovy ship libpqxx 6.x, +which has a bug which has been fixed in libpqxx 7.x. Fedora 33 ships +the newer version.

Install with docker

+ +

Docker installation

+

This is the easiest way to get Underpass up and running:

+
docker-compose up -d
+
+

Setup and run demo

+

Bootstrap the database for a country

+

Requirements:

+
    +
  • fiona (pip install fiona)
    • +
  • shapely (pip install shapely)
    • +
  • osm2pgsql (https://osm2pgsql.org/doc/install.html)
    • +
  • psql (https://www.postgresql.org/download/)
    • +
+

Run this utility script for bootstrap the database with data for a country:

+

cd setup && ./bootstrap.sh -r asia -c nepal -p 5439
+
+Regions (-r) are:

+
    +
  • africa
    • +
  • asia
    • +
  • australia-oceania
    • +
  • central-america
    • +
  • europe
    • +
  • north-america
    • +
  • south-america
    • +
+

Countries (-c) is the name of the country inside the region.

+

Data is downloaded from GeoFabrik, if you are not sure of what name you need to use, please check there.

+

Configure the UI

+

You can find the UI's playground here: http://localhost:8080

+

Edit this file with the center coordinates for the map:

+

js/src/fixtures/center.js

+

And copy it to the container:

+
docker cp js/src/fixtures/center.js underpass_ui:/code/src/fixtures/center.js
+
+

Refresh the page and you'll see your map centered in the new coordinates, +displaying raw data and validation results on top of the OSM map.

+

Keep the database up-to-date minutely

+

Run this command for start processing data from 2 days ago:

+
docker exec -d underpass underpass -t $(date +%Y-%m-%dT%H:%M:%S -d "2 days ago")
+
+

From MacOS, the date command is different:

+
docker exec -d underpass underpass -t $(date -v -2d +%Y-%m-%dT%H:%M:%S)
+
+

For running underpass as a daemon, use the -d option:

+
docker exec -d underpass underpass -t $(date -v -2d +%Y-%m-%dT%H:%M:%S)
+
+

Stop and start underpass

+

If you want to stop the process, you can kill the container:

+
docker kill underpass
+
+

Then, you'll have to run docker-compose up -d before starting the process again.

OSM Stats

+

The Red Cross maintains statistics of changes, so it’s possible to +track the mapping progress of individual users, teams, and mapping +campaigns. Underpass writes directly to the postgres database used for +OSM Stats. Underpass has the ability to recreate this database and +populate it with data from the raw data files. Underpass uses +replication change files to update these tables. The +database schema contains a number of tables which are documented here:

+

 

+

OSM Stats Tables

+

The OSM schema contains a number of tables, which are designed to +support the web front end. the raw_ tables are mostly static, and +are simply a matching of an ID to a name for display. There are other +smaller tables for the same purpose, usedc to group queries together +for the front-end.

raw_changesets Table

+

The main table is raw_changesets, which contains extracted data from +the two files is then processed to create the various statistics. The +counters use the existing data, and only add to this value based on +what is in the change file, as this requires much less processing +time. This is the primary table Underpass updates the data in.

Replication

+

Replication is the process of appyling a set changes to data. There +are two types of replication files available for OpenStreetMap data, +changesets and changefiles from their +planet server. The +level directory contains several subdirectories. All the +subdirectory structures are the same.

+

Each of the directories contains a 3 digit name. A new +directory is created whenever there are 1 million data files +created. Each of these top level's subdirectories contains 1000 +subdirectories, also named with a 3 digit value. Under those +subdirectories, there are 1000 entries. The time interval between map +updates is not consistent, so a state.txt file is used. This file +contains the timestamp of the accompanying data file. The data file is +compressed, and contains all the changed data.

+

For the change files, the directory structure looks like this:

+
minute/001/001/001/001.state.txt
+minute/001/001/001/001.osc.gz.
+minute/001/001/001/002.state.txt
+minute/001/001/001/002.osc.gz.
+etc...
+
+

Changesets are slightly different, as they contain no map data, just +data on the changes made when uploaded.

+
changesets/001/001/001.osm.gz
+changesets/001/001/001.state.txt
+etc...
+
+

Since the data file uses the same 3 digit prefix as the state file, +it's easy to get the right data for the timestamp. Because the size of +the data in the changefiles varies, plus CPU load, network latency, +etc... the time interval varies, so can't be calculated accurately. It +is possible to get a rough idea. Underpass makes the best guess it +can, and downloads a state.txt file that is close to the desired +timestamp. Using that initial state.txt file it's possible to +increment or decrement the prefix till the proper timestamp is +found. Then the prefix is used to download the data file for +processing.

Underpass command line utility

+

underpass is a command line utility for updating databases from +changesets and change files, and runs as a system daemon. Both change +files and changesets need to be applied to the database to stay in +sync. Change data can be downloaded from planet.openstreetmap.org +every minute, and has to be applied to the databases. Data is +processed as a stream, so a large disk for temporary files or much +memory isn’t needed.

+

The primary mode is to monitor the upstream change data for new files, +and to apply them. If the timestamp specifed is in the past, the +change data files are downloaded continuously until caught up with the +current time.

+

Each data source uses a different thread for multi-core support and +better performance. As files are downloaded from the different +sources, they are analyzed, and applied to the appropriate +database. Most of the work is done by the Underpass +library. underpass is the utility program that a uses the library.

+
underpass -h
+-h [ --help ]         display help
+-s [ --server arg]    database server (defaults to localhost)
+-m [ --monitor]       Start monitoring planet
+-t [ --timestamp arg] Starting timestamp
+-i [ --import ] arg   Initialize pgsnapshot database with datafile
+
+

By default, underpass uses the last date entered into the OSM Stats +datavase as the starting point. A different timestamp can also be +specified using --timestamp. All data files downloaded can +optionally be cached to disk, so furthur processing can use those and +save on network time.

Statistics Calculations

+

Underpass process two input streams for data, but only one is used for +the initial statistics calculations. ChangeSet are +used to populate some of the columns in the database, but aren't used +during statistics calculations by the backend. Only the +OsmChange file is used, as it contains the the data +that is changed.

+

The OsmChange data file contains 3 categories of data, what was +created, modified, or deleted. Currently only changed and modified +data are used for statistics calculations.

+

All of the changed data is parsed into a data +structure +that can be passed between classes. This data structure contains all +the data as well as the associated action, create or modify. The +parsed data is then passed to the +OsmChangeFile::collectStat() +method to do the calculations. While currently part of the core code, +in the future this will be a plugin, allowing others to create +different statistics calculations without modifying the code.

+

Priority boundary

+

Currently, changes to be proccessed are filtered by ChangeSetFile::areaFilter() +and OsmChangeFile::areaFilter(), using a boundary polygon. +In some cases is not possible to say if a OsmChange is inside +the priority boundary. To disable the filtering in the replication +process, you can add the argument --osmnoboundary for OsmChanges +or --oscnoboundary for Changesets.

+

What Is Collected

+

The original statistics counted buildings, waterways, and POIs. The +new statistics break this down into two categories, accumulates +statistics for things like buildings, as well as the more detailed +representation, like what type of building it is. The list of values +is configurable, as it uses a YAML file.

+

OpenStreetMap features support a keyword and value pair. The +keywords are loosely defined, +and over time some have changed and been improved. Often new mappers +get confused, so may use keywords and values in an inconsistent +manner. Also over time the definitions of some tags has changed, or +been extended.

+

For example, let's look at schools. There is a variety of ways school +buildings are tagged. Sometimes it's building=school, with school as +the value. Sometimes school is the keyword, and the value is the type +of school. In this case, the type of school is accumulated, as well as +a generic school count. Also if building=school isn't used, then +every school also increments the count of buildings.

+

Each category of data has the total accumulated value, as well as the +more detailed breakdown. For example, it's possible to extract +statistics for only hospitals, which is a subset of all the +buildings. As keywords and values can be in different feature +categories, some are checked for in multiple ways. Some keywords and +values may be spelled differently than the default, so variations are +also looked for to be complete.

+

To find all the common tags, several continents worth of data was +analyzed to find the most common patterns for the features we want to +collect statistics for. Mixed with inconsistent tagging schemes is +random capitalization, misspellings, and international spellings. The +attempt is made to catch all reasonable variations. +TagInfo was used to find totals +of some variations, with weird tagging that was not very common gets +ignored to avoid performance impacts, and data bloat.

+

Building Types

+

Most buildings added by remote tracing of satellite imagery lack any +metadata tags beyond building=yes. When local mappers import more +detailed data, or update the existing metadata, those values get +added. This is a common set of building values.

+
    +

Amenity Types

+

Most amenities are added by local mappers or through a data +import. Not all amenities are buildings, but for our use case that's +all that is analyzed. These are the common values for the amenity +keyword.

+
    +
  • hospital
    • +
  • school
    • +
  • clinic
    • +
  • kindergarten
    • +
  • drinking_water
    • +
  • health_facility
    • +
  • health_center
    • +
  • healthcare
    • +
+

Places Types

+

Places contain multiple features, and are mostly used to determine +local metadata improvements.

+
    +
  • village
    • +
  • hamlet
    • +
  • neighborhood
    • +
  • city
    • +
  • town
    • +
+

Highway Types

+

Highways traced from satellite imagery often lack metadata beyond the +functional type. For example, a highway that connects two villages is +easy to determine. An accumulated value for the total of highways, and +the total length in kilometers is store as an aggregate. More detailed +statistics are also kept allowing more detail when needed.

+
    +
  • trunk
    • +
  • tertiary
    • +
  • secondary
    • +
  • unclassified
    • +
  • track
    • +
  • residential
    • +
  • path
    • +
  • service
    • +
  • bridge
    • +
+

School Types

+

When school is a keyword, there are several values for the type of +school. An aggregate total of schools can be calculated, as well as detail +for the type of school.

+
    +
  • primary
    • +
  • secondary
    • +
  • kindergarten
    • +
+

Calculation Data flow

+

The data is processed by +Underpass. Underpass downloads +the changeset and the OsmChange files from the OpenStreetMap planet +server every minute. Downloaded files are also cached on disk, so it's +also possible to process data without a network connection. Once the +data is parsed from the respective data formats, it gets passed to the +OsmChangeFile::collectStat() +method. That method loops through the data structure containing the +changes to the map data. Within that method, it calls +ChangeSetFile::scanTags(), + which does all the real work. The scanTags() method uses StatsConfigSearch::search() to + search the lists of keywords and values configured at the stats configuration file. +ScanTags() returns an array of statistics for the desired features. +That array is then converted by collectStats() into the statistics data +structure, +and control returns to the processing thread.

+

The processing thread then passes the statistics data to +osmstats::applyChange(), +to insert them into the database.

+

changesets table

+

This is the primary table used to contain the data for each +changeset. All of the data is stored in a table for better query +performance on large data sets. It also limits needing SQL sub +queries or a +JOIN between +tables, reducing complexity.

+

An hstore is used to +store the statistics instead of having a separate table for each +feature to allow for more flexibility. An hstore is a key & value +pair, and multiple data items can be stored in a single column, +indexed by the key. This allows for more features to be added by the +backend and the frontend, without having modify the database schema.

+

An example query to count the total number of buildings added by the +user 4321 for a Tasking Manager project 1234 would be this:

+
+

SELECT SUM(CAST(added::hstore->'building' AS DOUBLE precision)) FROM +changesets WHERE 'hotosm-project-1234' = ANY(hashtags) AND uid=4321;

+
+

The source is the satellite imagery used for remote mapping.

Tests for statistics collection

+

As statistics are a key feature for Underpass, there are several ways to test +results and configurations.

+

Default

+

The default test will use two files:

+
    +
  • OsmChange (testsuite/testdata/test_stats.osc)
    • +
  • Stats results validation (testsuite/testdata/test_stats.yaml)
    • +
+

./stats-test

+

More testing

+

You can run other existing tests or create your own custom ones.

+

Stats extraction from a single file

+

Extract stats from file and print the JSON result:

+

./src/testsuite/libunderpass.all/stats-test -f stats/107235440.xml

+
{
+    "added":[
+        {"highway":8},
+        {"highway_km":64917794}
+    ],
+    "modified":[
+        {"highway":8}
+    ]
+}
+
+

Stats validation from files

+

If you want to assert the results agains a YAML file, add second -f argument:

+

./src/testsuite/libunderpass.all/stats-test -f /stats/107235440.xml -f /stats/107235440.yaml

+
    PASSED: Calculating added highway
+    PASSED: Calculating modified highway
+
+

The YAML file contain the expected results:

+
- modified_highway:
+  - 8
+- added_highway:
+  - 8
+
+

Collect stats

+

Run a replicator process from timestamp, incrementing the path and collecting stats from +OsmChange files. This is useful for doing a comparison with other sources (ex: Insights DB).

+

./src/testsuite/libunderpass.all/stats-test -m collect-stats -t 2021-05-11T17:00:00 -i 10 > result.json

+

Stats configuration file

+

Stats collection can be customized using a YAML configuration file.

+

In the following example, we have an OsmChange file with several nodes created, using +building and emergency keys for tags.

+

There are two different configurations for collecting stats from that file. +On statsconfig2.yaml , building, fire_station, hospital and police +are different categories of stats.

+

./src/testsuite/libunderpass.all/stats-test -f stats/test_statsconfig.osc \ + --statsconfigfile /src/testsuite/testdata/stats/statsconfig2.yaml

+

Running the command above, you'll see this results:

+
{
+    "added":[
+        {"building":1},
+        {"fire_station":2},
+        {"hospital":2},
+        {"police":1}
+    ],
+    "modified": []
+}
+
+

You can assert this results adding another -f argument:

+

./src/testsuite/libunderpass.all/stats-test -f stats/test_statsconfig.osc \ + --statsconfigfile /src/testsuite/testdata/stats/statsconfig2.yaml \ + -f stats/test_statsconfig2.yaml

+

On the other configuration file (statsconfig3.yaml) there are two categories for stats: building and humanitarian_building.

+

If you get stats from that file:

+

./src/testsuite/libunderpass.all/stats-test -f stats/test_statsconfig.osc \ + --statsconfigfile /src/testsuite/testdata/stats/statsconfig2.yaml

+

You'll see a different result:

+
{
+    "added":[
+        {"building":2},
+        {"humanitarian_building":4}
+    ],
+    "modified": []
+}
+
+

Again, you can assert the results:

+

./src/testsuite/libunderpass.all/stats-test -f stats/test_statsconfig.osc \ + --statsconfigfile /src/testsuite/testdata/stats/statsconfig2.yaml \ + -f stats/test_statsconfig2.yaml

+ + + + + + +
+
+ + +
+ +
+ + + +
+

Utility Programs

+

data/db/setupdb.sh

+

This is a simple shell script that creates all the databases Underpass +uses. It can also be used to initialize the two internal databases +Underpass uses, one for the *.state.txt files that contain the +timestamp of the data files, and the other is for the boundaries of +countries used to determine which country a change was made in for +statistics collection. These are used to bootstrap a new Underpass +installation.

+

setup/bootstrap.sh

+ +

utils/features2yaml

+

Get tags from the Map Features OSM wiki and output YAML

+

Use this script for output a YAML data model that will be used in +the configuration files inside /validation directory.

+

Usage

+
python features2yaml.py --category buildings > buildings.yaml
+python features2yaml.py --key building:material > building:material.yaml
+python features2yaml.py --url https://wiki.openstreetmap.org/wiki/Key:landuse
+python features2yaml.py --f ../../place.html
+
+

You may want to add more configuration parameters to +the YAML file later, like geometry angles or required +tags.

+

Dependencies:

+
    +
  • pip install beautifulsoup4
    • +
  • pip install requests
    • +
+

utils/xlstoyaml

+

Convert data models from XLSForms to YAML

+

Use this script for output a YAML data model that will be used in the +configuration files inside /validation directory.

+

Usage

+
python xls2yaml.py --category buildings > buildings.yaml
+
+

You may want to add more configuration parameters to the YAML file later.

+

utils/poly2geojson

+

Converts .poly to .geojson

+

Usage

+
python poly2geojson file.poly
+
+

utils/clean-osmchanges.sql

+

You may want to run this query if you're not processing raw data +and you want to just produce statistics.

+

This query deletes entries created from OsmChanges, +closed 1 day back or before , that has no corresponding Changeset.

+

We run this query every 24 hours for cleaning the database +when running the replicator process with areaFilter disabled +for osmchanges (--osmnoboundary).

Validating Data

+

It is important to make sure any data being added to OpenStreetMap is +of good quality. While there are number of other tools available to do +this, Underpass data validation is oriented towards real-time +analysis. Most all of the other tools have a time delay of hours or +days. As validation can be computationally intensive, there are two +levels of validation. Since Underpass is processing change files every +minute, the data validation must also fit within that time frame. Also +the data available in the minute updates is not often complete, so +some types of validation are impossible.

+

The first level of validation is simple, checking for the proper +values for tags. For buildings, the geometry can be checked to make +sure it's got 90 degree corners or is round. Also checks for +overlapping with other buildings in the same changeset is also +done.

+

The second level can't be done on huge datasets, but works well for +smaller datasets, for example a Tasking Manager project or a +county. This other level requires access to OSM data. Since querying a +large database may not be possible within the minute timeframe, this +is only enabled for datasets country sized or smaller. Using OSM data, +it's possible to identify duplicate buildings and highways.

+

The first level of data validation is applied to all changes, since it +can be completed within a minute. The second level of validation is +focused on Tasking Manager projects. The primary goal of this +secondary validation is to catch most mapping errors right away,

+

The Database

+

All mapping errors are written to a table called validation in the +Galaxy database. This table contains the OSM ID of the feature, the +changeset ID that contains this change, and the user ID of the mapper +making the change. The status column is an array of the issues. Those +issues include bad building geometry, bad tag value, orphan node, +duplicate buildings, overlapping buildings, and incomplete +tagging. The location of the feature is a single node, which can be +used for spatial filtering.

+

In addition, there are currently two debugging columns in the +database. One is the timestamp of when the validation is performed, +and the other is the calculated angle for buildings that are +determined to have bad geometry, which is used to debug the calculation.

+

Tag Validation

+

Organized mapping campaigns, especially those done on the ground using +(ODK)[https://opendatakit.org/] based mobile tools, have a defined set +of metadata tags. Often more detailed tags are added after remote +mapping by local mappers, as it's impossible to determine some +features from the satellite imagery, like building material.

+

HOT currently has a tool called +(MapCampaigner)[https://campaigns-staging.hotosm.org/], that is used +to validate tag completeness. Required tags are defined in a +(YAML)[https://www.yaml.org] config file. For example, to completely +map a building, the material of the walls of the building, the +material used for a roof, and whether it has walls. If the building is +an amenity, it should have a name and the type of amenity. The +existing list of tag values were based on what MapCampaigner uses, and +then extended by the Data Quality team at HOT. The current values are +listed in the config files:

+

amenities, + buildings, + highways, + solid waste, + landuse

+

By default, tag completeness is not enabled, as any data added by +remote mapping will always be missing tags, or have different +permissible values. Instead tag completeness can be used to monitor a +ground mapping campaign.

+

Bad Geometry

+

Often buildings are added that don't have square corners. This can be +eliminated by using a plugin for some map editors like JOSM to force +all new buildings to have the correct geometry. There are other +plugins that allow the mapper or validator to correct the +geometry. Flagging this error while the mapper is still active allows +for educating the mapper about this issue so they can improve their +quality, which might be as simple as having them use a building +plugin.

+

To determine the building correctness, a corner is chosen, and the +angle between the two lines is calculated, A threshold is then applied +so any building that looks rectangular to the user is considered +acceptable. That threshold value is in the YAML file for building +validation so it's easy to adjust.

+

Since Underpass is using minute change files, sometimes it's difficult +to validate buildings that have been edited, as not all the nodes in +the building polygon are in the change file. Most remote mapping only +adds buildings, any editing is done later by a human validator.

+

Highway Validation

+

Validating highways starts the correct tag value. More than validating +the values for the highway tag, this also will check the values of +important tags, like surface, smoothness, tracktype, and +sac_scale. The important validation is making sure any new highway +actually connects to the highway network. Otherwise navigation doesn't +work.
