[postgis-users] intersectionPatternMatrix documentation request

[Martin Davis]

You can also look at the OGC SFS document #99-049

Here:
http://www.opengeospatial.org/standards/sfs
or here:
http://www.loni.ucla.edu/twiki/pub/CCB/Meeting30March2005/99-049.pdf

Also, the JTS Javadoc has a lot of information on this, in the classes 
Geometry and IntersectionMatrix
