Lecture
Geometric spatial queries
Description
This lecture introduces SQL queries used to explore spatial geometries, covering topics such as extracting coordinates, dimensions, and reference systems from spatial geometries in a database. It also delves into SQL functions for geometric formats, repairing malformed geometries, and spatial relationships testing.
