Cut holes out of a polygon: the buildable part of a parcel once setbacks are removed, the land outside a protected area, the part of a route not already covered.

Cut holes out of a polygon: the buildable part of a parcel once setbacks are removed, the land outside a protected area, the part of a route not already covered. Order is significant, so this is the one overlay op where swapping the operands gives a different answer. Subtracting everything answers geojson:null with empty:true, a real answer rather than an error. Send a FeatureCollection of Polygons or MultiPolygons; the first member in document order has every later member subtracted from it. The answer is a single Feature, or null with empty:true when nothing survives. Clipping is planar in longitude/latitude, so edges are straight in degrees rather than geodesics. The 2000-position cap is CPU rather than bandwidth: the sweep-line overlay is quadratic on self-intersecting input. Input is EPSG:4326 only. Limits: 2000 positions across all members, 1 MiB request body, and at least two polygonal geometries or the call is refused.
