Detailed Description

Ever/always spatial relationships for temporal rigid geometries.

These relationships compute the ever/always spatial relationship between the arguments and return a Boolean. These functions may be used for filtering purposes before applying the corresponding spatiotemporal relationship.

The following relationships are supported: contains, disjoint, intersects, touches, and dwithin.
