The topological and distance relationships described in the section called “Spatial Relationships” such as eIntersects, aDwithin, or tContains only consider the location of the geometries, not their orientation. To be able to apply these spatial relationships to the temporal poses, they must be transformed to temporal geometry points. This can be easily performed using the functions geometry and tgeompoint or using an explicit casting :: as shown in the examples below.
