ETRS89 or ITRS coordinate reference system

Purpose: Test that the data is provided using at least one geographical coordinate system based on ETRS89 in continental Europe and ITRS outside continental Europe.

Prerequisites

Test method

  • Send a getCapabilities request to the service endpoint. Into the response:

    • For each Layer element:

      • Check that the TileMatrixSetLink is the identifier of a TileMatrixSet.

      • Check manually that the TileMatrixSet has either no SupportedCRS element or one that matches the CRS identifier of one of the ETRS89 based or ITRS based coordinate systems.

Reference(s):

  • TG VS, Chapter 5.2.3.3.4.7, Requirement 89

Test type: Automated/Manual

Notes

The multiplicity of SupportedCRS element is 0 or more.

The test is partially manual until a machine-readable "whitelist" register of the acceptable CRSes with their CRS identifiers and commonly used aliases ("label" and "URL" versions) is available.

Contextual XPath references

The namespace prefixes used as described in README.md.

Abbreviation XPath expression (relative to /Capabilities)
Layer Contents/Layer
TileMatrixSetLink Contents/Layer/TileMatrixSetLink
TileMatrixSet Contents/Layer/TileMatrixSet/ows:Identifier
SupportedCRS Contents/Layer/TileMatrixSet/ows:SupportedCRS
