Get source coverage map GeoJSON

Returns the declared source-coverage GeoJSON layer used by the interactive docs map. Features associate public reference boundaries or generalized selection regions with source IDs, source names, official upstream URLs, panel links, readiness, license metadata, and geometry notes. The layer does not redistribute source-native parcel, permit, assessor, utility, building, zoning, or hazard geometry.
