So are there libraries out there to use these TINs in analysis? As a few examples, I'd like to be able to 1 - create a TIN create from various features, including, for example, an ogr polyline3d layer 2 - query a TIN at an xy location and return the z value 3 - calculate TIN volumes above/below z planes 4 - visualize these TINs Bryan _______________________________________________ Geowanking mailing list [email protected] http://lists.burri.to/mailman/listinfo/geowanking
