GeoServer is a Java-based server that allows users to view and edit geospatial data. Using open standards set forth by the Open Geospatial Consortium (OGC), GeoServer allows for great flexibility in map creation and data sharing.
Open and Share Your Spatial Data
GeoServer allows you to display your spatial information to the world. Implementing the Web Map Service (WMS) standard, GeoServer can create maps in a variety of output formats. OpenLayers, a free mapping library, is integrated into GeoServer, making map generation quick and easy. GeoServer is built on GeoTools, an open source Java GIS toolkit.
There is much more to GeoServer than nicely styled maps. GeoServer conforms to the Web Feature Service (WFS) standard, and Web Coverage Service (WCS) standard which permits the sharing and editing of the data that is used to generate the maps. GeoServer also uses the Web Map Tile Service standard to split your published maps into tiles for ease of use by web mapping and mobile applications.
GeoServer is a modular application with additional functionality added via extensions. An extension for Web Processing Service opens up a wealth of processing options, you can even write your own!
Enable others to incorporate your data into their websites and applications, freeing your data and permitting greater transparency.
