AgendaOrigins of the projectWhat is gvSIG?OK, but what can gvSIG do for me now?The near and mid-term futureConclusions


Origins of the projectIn 2003 CIT decides to migrate to Free Software (gvPONTIS), why?

Better usage of incoming budgetPromote local industryTechnology independence

At this time, no free CAD or GIS availableLaunch a brand new projectFrom a local to a global project

a desktop GISMain characteristics:

Developed in JavaRuns in Windows, GNU/Linux and MacOSModular and extensibleFast developmentQuite similar to ESRI ArcView 3.2 interfaceUses the best Free Software components



free softwareIt's Free Software (GPL), so you can

New organizational structureThe project is growing really fastIt needs a better organizational structure to:

Assure the future and independence of the projectGet involved more companies and administrationsConnect with other (geo) organizations

Working projects in that contextCreate a translation and documentation portalPromote a repository for contributionsCollaborative testing

ConclusionsgvSIG is a mature desktop GIS It can be used to perform most common tasksIt can be extended and improvedThere are many actors involved in the projectThe community is growing
