MapServer is an open-source development environment for building spatially enabled internet applications, built in the C language, and is widely known as one of the fastest Web mapping engines available. It can run as a CGI program or via MapScript which supports several programming languages (using SWIG). MapServer can access hundreds of data formats, any raster or vector format supported by

and be named "MapServer Enterprise". The existing MapServer application would be renamed "MapServer Cheetah". This name change was overwhelmingly opposed by the MapServer community. Autodesk then backed off this name change and retained the name, "MapGuide" for its product. Also, plans to establish the MapServer Foundation were scrapped; Instead, the Open Source Geospatial Foundation (OSGeo) was established in 2006 to include MapServer and other open source GIS projects (which includes MapGuide Open Source).

Timeline

''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. * 1997-07: MapServer 1.0, Developed as Part of the

ForNet Project. Grew out of the need to deliver

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. * 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''. * 2001-06: MapServer 3.2 released with MapScript 1.0, like CSS, adds layout flexibility. * 2002-06: MapServer 3.5 was rewritten, and added support for
