public class MapDataPreprocessor
extends FilterByGraphicType

Handles transformation of coordinates from one system to another. Both reverse and forward projection are provided, along with input and output scaling and offsets. This allows going from feet to meters, latlong to feet/meters/etc., feet/meters/etc. to latlong, or from one projection in feet/meters/etc., to latlong, and thence to another projection in feet/meters/etc. For truly weird transformations, write a special implementation of Projection.
