Juan Garcia writes to say that his Geo Utilities website has been updated. I’ve posted about this site before; it has a number of tools for Google Earth KML files, including:
- Simplification (reduction of the number of vertices
- Area calculation
- Topology (find the intersection points between a path and the perimeter of a polygon)
Updates include modification of the algorithms to speed them up, and a download link to the source code, released under the GPL.
