Open Source WorldMap - Collaborative Mapping Tool - in Alpha

WorldMap ALPHA is an experimental platform designed for viewing and interpreting maps collaboratively. Today maps come from many sources and take many forms, from paper atlases to digital satellite images to census files. WorldMap aims to pull these and other hard-to-find maps together and make them available to researchers to explore, share, annotate, and remix.

WorldMap combines modeling capabilities of Geographic Information Systems (GIS) with current web technologies, and is made available as Open Source software. Use the hosted version of WorldMap here or download and run the application on your own server. WorldMap stands on the shoulders of other Open Source projects including AfricaMap, GeoNode, OpenLayers, PostGIS, and GEOS. WorldMap is licensed under Version 3 of the GNU General Public License (GPL).
