Hi,
Yes, I can see this being a killer app for many use-cases, which makes GGL very useful to many, even without a spatial index.
Thanks for this. I like to add that GGL is more than polygon clipping alone! The most simple and obvious algorithms are all included in a generic way: distance, area, point-in-polygon. I think many users could profit from that as well, without reinventing the wheel each time. I agree that these algorithms are not that difficult, but they are implemented here for cartesian, spherical coordinate systems and for more geometry types or geometry type pairs, which is not trivial.
Exactly. I want to add another thing which makes GGL very useful: The actual instantiations of the concepts. Having them inside boost goes a long way in standardizing them. This makes it extremely important that the concepts are general and generic, which I am confident they are. Regards Fabio
