Hi!

I am currently doing research on UML modeling of cadastre and land 
administration data. On a Object Diagram, there is a situation where a check 
should be done on the projected straights of a building outline (original 
building to be depicted in 3D), in order to see if it is contained within a 
land parcel (depicted on a 2D planar partition).

I check both the ISO 13249-3 (SQL/MM Part3: Spatial) and PostGIS documentation 
and could not find any explicit reference. So, can PostGIS do this kind of 
check?
