Area to query: a Polygon or MultiPolygon, a Feature wrapping one, or a FeatureCollection of
them, such as the PolygonFeatures that geometryData returns.
Remarks
The API only accepts a bounding box, so the request is sent with the polygon's bounding box and the
response is then trimmed to the incidents that intersect the polygon. A LineString incident that
crosses the boundary is kept. The 10,000 km² limit applies to that bounding box.
Parameters for fetching incidents within a polygon, such as a city boundary.
