Detailed Description
Spatial relationships for temporal points.
These relationships project the time dimension and return a Boolean. They are thus defined with the "at any instant" semantics, that is, the traditional spatial function is applied to the union of all values taken by the trajectory of the temporal point. These functions are typically used for filtering purposes, before applying the corresponding temporal spatial relationship.
The following relationships are supported for geometries: contains, disjoint, intersects, touches, and dwithin.
The following relationships are supported for geographies: intersects, dwithin.
Only dwithin and intersects are supported for 3D geometries.
