About MapServer

MapServer is a development environment for building spatially-enabled web mapping applications and services. It is fast, flexible, reliable and can be integrated into just about any GIS environment. It supports many popular spatial data formats including OGC web services.

MapServer features MapScript, a powerful scripting environment, that supports PHP, Python, Perl, C#, Java and more. Using MapScript makes it fast and easy to build complex geospatial web applications.

  • Also take a look at MapServer Development statistics at Ohloh. Here are some excerpts:
    • 27 developers: " Over the past twelve months, 12 developers contributed new code to MapServer. This is a relatively large team, putting this project among the top 5% of all project teams on Ohloh. For this measurement, Ohloh considered only recent changes to the code. Over the entire history of the project, 27 developers have contributed."
    • Mature, well-established codebase: "The first lines of source code were added to MapServer in 2000. This is a relatively long time for an open source project to stay active, and can be a very good sign.
      A long source control history like this one shows that the project has enough merit to hold contributors's interest for a long time. It might indicate a mature and relatively bug-free code base, and can be a sign of an organized, dedicated development team."
      Note: The source code for MapServer is actually older than the source control history. The project started around 1996 but started using CVS only in 2000.
