The Geometry module provides an implementation of OGC Feature Geometry Abstract Specification (ISO 19107) (a.k.a. Topic 1 - Feature Geometry).

As there aren´t existing too many approaches for a 19107 GeoAPI implementation yet, this implementation will serve as a test of the capability of the GeoAPI (in fact for TC211 too, since GeoAPI is partially derived from the TC211 specs) as well. Thus, we will report a list of suggestions to GeoAPI / GeoTools in order to contribute a part to the improvement of the GeoAPI by "Best Practise".
Adrian Custer is looking into the larger problems of making ISO19107 Geometry implementation that can respond to the CoordianteReferenceSystem definition by delegating to a range of operations. This module uses linear solutions (ie 2D space) for operations such as buffer and intersects; when working with geometries defined by great circles on a sphere a different implementation should be used.
In more simple terms; we need to have a double dispatch using both Geometry and CRS in order to determine the correct operation to execute.
