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 basic algorithms, concepts and coordinate system definitions supplied by PROJ.4 are exposed via a Java class model which follows standard Java conventions and OO best practices.

Proj4J is a part of the MetaCRS group of projects, hosted by OSGeo.


Status: Currently this library is still being created, and is not yet ready for download
