Hi Frederick,
Thanks - regarding the inverse function returning a Point2D object, there may be some projections that do not return a LatLonPoint. The Cartesian projection, for instance, doesn't. GeoProj Projections will return a LatLonPoint from the inverse method.
If you have a generic Projection handle on a projection object and need a LatLonPoint without scoping it, there's an inverse() method that allows you to provide the return object you want. You can provide a LatLonPoint there. If you have a GeoProj handle to a projection object, the inverse method will return a LatLonPoint.
Hope this helps,
Don
