Description (last modified by hobu) 

It would be nice to add topology validation (like JTS's IsValidOp(geom))for a
single geometry in OGR and ogr.py.  For instance, polygons are not
self-intersecting, no zero-length edges, etc.

Jump (using JTS) has the following functionality that probably would also be
present in GEOS?:

* basic topology
* repeated consecutive points
* polygon orientation
* minimal segment length
* minimal angle
* minimal polygon area
* only selected geometry types
