GeoServer is …
an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards.
GeoSolutions, an open-source consulting company, has created a free GeoServer workshop disc in iso format. You can run this iso in a free virtual machine environment like VirtualBox, or burn it on a DVD to use as a bootable Ubuntu Linux OS disc, or to install it on a computer. The disc contains:
- Tutorials on installing GeoServer, running it, adding data and querying it, and Google Earth/Maps support
- An installation of GeoServer with sample data
- Copies of the GIS programs uDIG and qGIS, which support creating datasets for use with GeoServer
