Detailed Description

Bounding box operators for spatiotemporal values.

These operators test the bounding box of spatiotemporal values, which is anSTBox, where the x, y, and optional z coordinates are or the space (value) dimension and the t coordinate is for the time dimension. The following operators are defined: overlaps, contains, contained, and same.

The operators consider as many dimensions as they are shared in both arguments: only the space dimension, only the time dimension, or both the space and the time dimensions.
