GEOSGeometry.covers(other)
New in Django 1.10.
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)
