Java Native Interface for PROJ C/C++ library. PROJ is a generic coordinate transformation software that transforms geospatial coordinates from one coordinate reference system (CRS) to another. This includes cartographic projections as well as geodetic transformations. This package exposes PROJ services as implementations of GeoAPI interfaces. Both PROJ and GeoAPI are modeled according the ISO 19111 international standard. Latest release is 2.0.
