For more than 15 years, the Region of Paris has been building a regional GIS covering different thematic fields: economy, demography, planning, environment, transportation, public buildings, etc. The Paris regional planning agency, the IAURIF, has developed a PC-based application being used by a team of more than 100 professionals (engineers, architects, economists, etc.). This application provides them with very user-friendly tools for accessing the GIS in their everyday tasks. Directly from their PC, they can view and browse the data on screen (MapObjects maps) or ask for paper maps anywhere in the region (remote AML-driven ARCPLOT cartography). They can also get some explanation on the Paris regional GIS, its content (metadata for nonspecialized users), and some updated news about this GIS. Last September, this application won the application contest organized by Esri France.
