In computing, GeoServer is an open-source server written in Java that allows users to share, process and edit geospatial data.

GeoServer reads a variety of data formats,[4] including: Through standard protocols it produces KML, GML, Shapefile, GeoRSS, PDF, GeoJSON, JPEG, GIF, SVG, PNG and more.

GeoServer additionally supports efficient publishing of geospatial data to Google Earth through the use of network links, using KML.
