= Welcome to Proj4J = Proj4J is a Java library to transform point coordinates from one coordinate system to another, including datum transformations. The core of this library is a port of the [http://trac.osgeo.org/proj/ PROJ.4] C library. The basic algorithms, concepts and coordinate system definitions supplied by PROJ.4 have been exposed via a class model which follows standard Java conventions and OO best practices. Proj4J is a part of the [http://wiki.osgeo.org/wiki/MetaCRS MetaCRS] group of projects, hosted by [http://osgeo.org OSGeo]. == Download == '''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. == Documentation == * The current [http://trac.osgeo.org/proj/#Documentation PROJ.4 documentation]. == Related Resources == * The PROJ.4 site has a comprehensive list of [http://trac.osgeo.org/proj/#RelatedResources resources] dealing with Coordinate Systems in general and the PROJ.4 library in particular.
