Name

CG_Distance — Computes the minimum distance between two geometries

Synopsis

double precision CG_Distance( geometry geomA , geometry geomB );

Descripción

Computes the minimum distance between two geometries.

Performed by the SFCGAL module

[Note]

NOTE: this function returns a double precision value representing the distance.

Availability: 3.5.0

This method needs SFCGAL backend.

This function supports Triangles and Triangulated Irregular Network Surfaces (TIN).
