[postgis-users] Invalid Geometry

[Joseph Spenner]

Did you try ST_MakeValid, and compare the before/after?   Might provide some info.

I'm using PostgreSQL 9.5 and during processing my 3D dataset I receive invalid geometry of  polyhedral surfaces, although the geometry seems correct. The error is: too few points in geometry component. How can I fix this problem?

SELECT st_isvalidreason(ST_geomfromtext('POLYGON Z ((445541.707540942 5444906.92146704 5.2,445541.707540942 5444906.92146704 3.69,445541.560237253 5444906.88199714 3.69,445541.560237253 5444906.88199714 5.2,445541.707540942 5444906.92146704 5.2))')) as valid
Thanks
