)
;
Computes the minimum distance between two geometries.
Performed by the SFCGAL module
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).
