+An ellipsoid region may also be confined to a specific latitude and/or longitude range. The `minLatitude` and `maxLatitude` properties represent the latitude values at which the region starts and stops, defined in the range `[-pi/2, pi/2]`. Similarly, the `minLatitude` and `maxLatitude` properties represent the longitude bounds within the range `[-pi, pi]`.
