Here is a Collaborative Mapping platform, version 0.12 that we have built - it is based on OpenLayers + wt
In the current version, it can load district boundary maps and GPS tracks. Based on the GPS tracks, one can create (trace, draw) new data layers - river boundaries, road tracks, and even points and polygons. A peek is at http://lsi.iiit.ac.in/wt/vgis.wt Also, Attributes in any language can be added - pls test and let us know. Looking forward to your comments and suggestions. -- Rashad
