= 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].
