geOrchestra is a free, modular and interoperable Spatial Data Infrastructure software born in 2009 to meet the requirements of the INSPIRE directive in Europe.

geOrchestra’s core features a security proxy and a single-sign-on authentication system. Next to this core are independant and interoperable modules to build your own Spatial Data Infrastructure:

Modules interact using OGC interfaces or REST APIs.

Initially covering Brittany, then France, geOrchestra now spreads worldwide with SDIs in Bolivia, Nicaragua, Switzerland and India.
