The document discusses online community mapping and proposes a model for collaborative geospatial mapping using open source technologies. It outlines how social software tools like wikis, blogs, social bookmarking and tagging can be combined with geographic information systems and open standards like GML and SVG to allow public participation in mapping and sharing of user-generated geospatial data. Mechanisms like permalinks, trackbacks, and RSS/Atom feeds enable social interaction and discourse around geo-located content. Examples show how social software is being used to facilitate collaborative geospatial mapping online.
