CTS

Coordinate Transformation Suite (abridged CTS) is a library developed to perform coordinate transformations using well known geodetic algorithms and parameter sets. It strives to be simple, flexible and interoperable, in this order.

History

Originally developed by Michaël Michaud under the name JTransfoCoord and then JGeod, the library was renamed to CTS in 2009. Today CTS is maintained by the OrbisGIS team in collaboration with Michaël Michaud.

The new CTS has been funded by the French Agence Nationale de la Recherche (ANR) under research contract ANR-08-VILL-0005-01 and the regional council of the Région Pays de La Loire under the Système d'Orbservation Géographique de la Ville (SOGVILLE) project.
