Comment (by mdavis):
This would be even more useful if the DE9IM pattern functionality was
enhanced to allow more expressive patterns. In particular, an "OR"
capability would allow expressing relationships such as "polygons which
share an edge or whose interiors intersect". (This is useful to support
clustering/unioning polygons which are adjacent or overlapping, but not
just touching at single points).
A syntax supporting OR could be:
{{{
****1*****|T********
}}}
While we're at it, it would be nice to allow a "dotted notation" for DE9IM
patterns, for easier reading:
{{{
***.*1**.***|T**.***.***
}}}
