MapServer is an open source development environment for building spatially-enabled web mapping applications and services. It is fast, flexible, reliable and can be integratated into just about any GIS environment. Originally developed at the University of Minnesota, MapServer is now maintained by developers around the world.
MapServer runs on all major operating systems and will work with almost any web server.
