[OSM-dev] Truncating geometries

[Sebastian Kürten]

Hi Malcolm,

I recently published a new project called osm4j which can be used to
achieve this. The wiki [1] already contains pointers to resources about
the project. The tutorial [2] may be helpful as well, espescially the
sections about building geometry [3] and about applying polygon
operations [3].

Basically the library allows you to build JTS objects from ways and
relations (LineString, Polygon and MultiPolygon) and apply the
operations from the Geometry [5] class to do intersections with
arbitrary polygons.
