Harvard WorldMap is an online, open source mapping platform developed to lower barriers for scholars who wish to explore, visualize, edit, and publish geospatial information.  The system attempts to address the gap between desktop GIS which is generally light on collaboration, and web-based mapping systems which often don't support the inclusion of large datasets.
