What are some recommended frameworks for manipulating spatial data in C++?
c++, geospatial, polygon, spatial
Solution
GEOS is an open source (LGPL) C++ geometry / topology engine. Might suit you?
Useful places to look for this stuff are this useful article on the O'Reilly website and also OSGeo which is a collaboration to support open source geospatial stuff.
Problem
What are some recommended frameworks for manipulating spatial data in C++? I'm looking for a polygon object, point object, and some operations like union, intersection, distance, and area. I need to enter coordinates in WGS84 (lon,lat) and get area in square km. I would prefer a free/open source framework, but am open to suggestions. Edit: Unfortunately I need a non-GPL solution. LGPL is alright.
