Dear PostGIS users,
I would like to query if a point is located in the TIN
object. My TIN object is closed (convex hull) object (i.e. surface of a
round object). I tried to use ST_Within, but the error message returns
ERROR: Unknown geometry type: 15 - Tin
My query is as follows:
SELECT ST_Within(mypoint,mytinobject) As mypointinmytinobject
(SELECT ST_GeomFromText('POINT(x,y,z)', SRID) As mypoint,
(SELECT geom FROM mytintable WHERE gid=1) As mytinobject
) As myobjects;
What are the equivalent 3D query functions like ST_Within for 3D TIN object in PostGIS?
Thanks in advance.
