Open Source Geographic Coordinate Systems and Projections

13 March 2009 Geoff Zeiss

There are several coordinate system related projects at the Open Source Geospatial Foundation (OSGEO)), including

Proj4

A cartographic projections library originally written by Gerald Evenden then of the USGS.

Proj4js 

A JavaScript library to transform point coordinates from one
coordinate system to another, including datum transformations.

CS-MAP

Coordinate systems projections library written by Norm Olson, then of Mentor Software. It is used by AutoCAD Map 3D and MapGuide Open Source. The library was acquired by Autodesk and donated to OSGEO.

GeoTIFF

Libgeotiff is an open source library for reading and writing GeoTIFF information tags.

MetaCRS/libgeotiff

The folks responsible for these projects have gotten together and formed an overarching project called MetaCRS.  The plan is for all coordinate system activities at OSGEO to be part of one umbrella project, sort of a one stop shop for coordinate system related activities. This will provide an opportunity for cooperating including on coordinate system dictionaries, test suites and mathematical formulations.

The project steering committee is comprised of, Frank Warmerdam (chair), Hugues Wisniewski, Norm Olson, and Mike Adair.

with the following sub-projects and leads:
