Origins of the project Capabilities
Future
Conclusions
In 2003 CIT decides to migrate to Free
Software (gvPONTIS), why?
Better usage of incoming budget
Promote local industry
Technology independence
At this time, no free CAD or GIS available
Launch a brand new project
From a local to a global project
