This page is meant to gather information on use cases and suggested solutions to provide support for multiple polygons per story, or feed entry.

Use Cases

In several use cases it's necessary to use a multipolygon to define a location that is the aggregation of several polygons (MULTIPOLYGON) This is not an event in multiple locations, it's a item that has some kind of geometry impossible to draw in a single polygon

Some example of such non-continuous polygons are satellite data, landcover and other environmental data, some electoral districts in the US or municipalities in Portugal.
