MapServer is an open source development environment for building spatially enabled internet applications. It can run as a CGI program or via MapScript which supports several programming languages (using SWIG). MapServer was developed by the University of Minnesota — so, it is often and more specifically referred as "UMN MapServer", to distinguish it from commercial "map server". MapServer was originally developed with support from NASA, which needed a way to make its satellite imagery available to the public.[2]

Open Source Geospatial Foundation[edit]

In November 2005, Autodesk, the MapServer Technical Steering Committee Members, the University of Minnesota, and DM Solutions Group announced the creation of the MapServer Foundation.[3] With this announcement, Autodesk announced that its internet mapping application, MapGuide, would be developed as an open source application with all new code and be named "MapServer Enterprise".[3] The existing MapServer application would be renamed "MapServer Cheetah".[3] This name change was overwhelmingly opposed by the MapServer community.[4] Autodesk then backed off this name change and retained the name, "MapGuide" for its product.[4] Also, plans to establish the MapServer Foundation were scrapped; Instead, the Open Source Geospatial Foundation (OSGeo) was established to include MapServer and other open source GIS projects (which now includes MapGuide Open Source).[5]


MapServer has had an important role in Web mapping history. The following is a summary of its evolution:

  • 1994: UMN awarded with NASA/ForNet funding to support web-based delivery of forestry data.[6]
  • 1997-07: MapServer 1.0, Developed as Part of the NASA ForNet Project. Grew out of the need to deliver remote sensing data across the web for foresters.
  • 1998-07: MapServer 2.0 released as final ForNET deliverable; added reprojection support (PROJ.4).
  • 1999: UMN makes MapServer an open source project.[6]
  • 2000-06: MapServer 3.0 was developed as part of the NASA TerraSIP Project. This is also the first public, open source release of UMN MapServer.[7]
  • 2001-06: MapServer 3.2 released with MapScript 1.0, like CSS, adds layout flexibility.
  • 2002-06: MapServer 3.5 was rewritten,[8] and added support for PostGIS and ArcSDE. Version 3.6 adds initial OGC WMS support.
  • 2003-07: MapServer 4.0, adds 24bit raster output support and support for SWF.
  • 2005-04: MapServer 4.6, adds support for SVG.
  • 2007-09: MapServer 5.0 released, introducing Anti-Grain Geometry (AGG) graphics library.
  • 2011-05: MapServer 6.0 released, adds support for opengl & KML output, with 5.6.X as stable versions.
  • 2012-11: MapServer 6.2 released, adds support for INSPIRE services. Released along TinyOWS and MapCache.
  • 2013-09: MapServer 6.4 released.[9]
  • 2015-07: MapServer 7.0 released.[10]
