The invention is an Internet based Geographic Information System (GIS), which resides totally on Internet servers, allowing users to access and use the system on the Internet from a browser or equivalent, thus requiring no user installed software. The system provides enough core GIS capability to allow creation of GIS data layers but is user friendly enough to provide access to users who are not GIS specialists. The system supports sharing of data among users, and supports data compatibility with platform based GIS installations. Use of the novel GIS permits communities of users sharing common interests associated with a geographical area to communicate using a map base medium.
