 From the official [Fortaleza Maps Portal](https://mapas.fortaleza.ce.gov.br/), I downloaded the neighborhoods and parks files. Since they are in the `Esri Shapefile` format, they come in `.zip` folders containing multiple files (`.dbf`, `.prj`, `.shp`, `.shx`), all of them necessary. To avoid creating a mess, we can use `shp_extract_read()`: Just specify the path and you're done! You can also give a `dsn` (data source name) extension. By default, `dsn = shp` but you can also use `dsn = ` `geojson`, `kml` and so on. Other `st_read()` arguments can also be passed. Here, we define the `options` argument to ensure the `latin1` encoding, otherwise this file won't work.
