Object geometries

Basic principles

This web service returns the geometry of objects in geojson format, filtered by layer, and optionally by bounding box. Available only for vector type layers (cf. the web service for the list of layers).

Availability

This web service is available with Geoconcept Web by setting the services.activate.getFeatures parameter to true (cf. advanced settings section).
