For a future release, it would be helpful if we could map using GeoJSON & KML point and polygon:
For type "Point", the "coordinates" member must be a single position.
For type "Polygon", the "coordinates" member must be an array of LinearRing coordinate arrays. For Polygons with multiple rings, the first must be the exterior ring and any others must be interior rings or holes.
