Paul, so the status quo for now in gereral openjump development is to modify the geometries under the mentioned entities.. and to keep a more difficult to realise reprojecting rendering to later?
so you want to integrate reprojecting in the core? is this correct? regards ede -- > Larry, > > Alevel we should probably have a utility class that would reproject a > Category,a Layer, a FeatureCollection > > In JUMP we should have some high level utility methods to reproject the > following.
