gis.geos.GEOSGeometry.covers()

GEOSGeometry.covers(other)

Returns True if this geometry covers the specified geometry.

The covers predicate has the following equivalent definitions:

• Every point of the other geometry is a point of this geometry.
• The DE-9IM Intersection Matrix for the two geometries is T*****FF*, *T****FF*, ***T**FF*, or ****T*FF*.

If either geometry is empty, returns False.

This predicate is similar to GEOSGeometry.contains(), but is more inclusive (i.e. returns True for more cases). In particular, unlike contains() it does not distinguish between points in the boundary and in the interior of geometries. For most situations, covers() should be preferred to contains(). As an added benefit, covers() is more amenable to optimization and hence should outperform contains().
