Geospatial Data

Shapes

Sometimes it is necessary to obtain a shape for the boundaries of some OSM relation. For example for a city or a region. To do it, there are two commands available: wkt to get this data in the "WKT (Well-Known-Text)" format or geojson to get the data in GeoJSON format.

In both commands you can use following parameters:

Parameter Description
relation Relation ID. 
    # SWITCHING TO THE GEO CONTEXT
- geo:
    provider: osm
    do:
    # Get shape in WKT format for specific OSM relation
    - wkt:
        relation: 62366
        do:
