#4363 new enhancement

Create ST_3dIsValid function

Reported by: johnpowell Owned by: pramsey
Priority: medium Milestone: PostGIS Fund Me
Component: postgis Version: master
Keywords: isvalid, 3d, sfcgal Cc:

Description

The existing Postgis ST_IsValid function only works in 2D, as can be seen from:

SELECT ST_IsValid('LINESTRING Z (0 0 0,0 0 10)'); NOTICE: Too few points in geometry component at or near point 0 0 0

sfcgal contains a 3D IsValid function, which could be used for this purpose, see, ​https://github.com/Oslandia/SFCGAL/blob/master/src/algorithm/isValid.cpp
