Welcome to Proj4J
Proj4J is a Java library to transform point coordinates from one geographic coordinate system to another, including datum transformations.
The core of this library is a port of the PROJ.4 C library. The projection algorithms, concepts and coordinate system definitions are all taken directly from PROJ.4. They are exposed via a Java class model which follows standard Java conventions and OO best practices.
Status: Currently this library is still being created, and is not yet ready for download
- The current development source is available via anonymous SVN from http://svn.osgeo.org/metacrs/proj4j.
- The PROJ.4 documentation is the best reference for details of the coordinate system specification language, projection algorithms and supported parameters.
- the Version History lists the evolution of features of the library
A mailing list is available for users and developers of Proj4J. Subscription, unsubscription and a web archive can be found at http://lists.osgeo.org/mailman/listinfo/proj4j.
- The PROJ.4 site has a comprehensive list of resources dealing with Coordinate Systems in general and the PROJ.4 library in particular.
