The Center for Geographic Analysis at Harvard recently announced Version 1.0 of WorldMap, a milestone in our longstanding effort to build a public technology platform to support research collaboration around geospatial information at Harvard. WorldMap is open source software and provides scholars anywhere in the world with the tools to discover, organize, visualize, create, share, and publish geographically referenced information. WorldMap attempts to fill a growing niche between powerful desktop-bound mapping applications and lightweight web solutions.
