Remarks
The ST_Dimension function returns the topological dimension of the geometry: 0 for points, 1 for lines and curves, 2 for polygons and surfaces. For geometry collections, returns the maximum dimension of all components. The dimension represents the number of degrees of freedom in the geometry's coordinate space, not the coordinate system dimensions. For Geometry types in planar coordinate systems, this is useful for classifying feature types, validating geometry types, or filtering by dimension. OGC-compliant.
