MapServer History

This page will act as a sandbox for compiling notes on the history of MapServer, for publishing to the main MapServer website, as well as Wikipedia.

The project was born of necessity and frustration with commercial Web-based mapping offerings available in the mid-1990s. The initial interest was in developing spatially-enabled Web applications and not the software to make that possible.


  • when was GDAL initially implemented by/for who (CFS / GeoConnections?)?
  • when was OracleSpatial support developed by Rodrigo Cabral of CTTMAR/UNIVALI, Brazil? For who?


  • initial effort to develop decision support system for recreational users of the Boundary Waters Canoe Area Wilderness (BWCAW) in northern Minnesota, USA
    • initially basic configuration to submit web requests to AML routines, rendered with ArcPlot
    • 30 seconds to render maps
    • licensing limitations
