Concept
GeoServer
Résumé
In computing, GeoServer is an open-source server written in Java that allows users to share, process and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer has evolved to become an easy method of connecting existing information to virtual globes such as Google Earth and NASA World Wind as well as to web-based maps such as OpenLayers, Leaflet, Google Maps and Bing Maps. GeoServer functions as the reference implementation of the Open Geospatial Consortium Web Feature Service standard, and also implements the Web Map Service, Web Coverage Service and Web Processing Service specifications.
GeoServer aims to operate as a node within a free and open Spatial Data Infrastructure. Just as the Apache HTTP Server has offered a free and open web server to publish HTML, GeoServer aims to do the same for geospatial data.
GeoServer reads a variety of data formats, including:
PostGIS
Oracle Spatial
ArcSDE
IBM Db2
MySQL
MongoDB
Apache Solr
s
GeoTIFF
GTOPO30
MrSID
JPEG2000
Through standard protocols it produces KML, GML, Shapefile, GeoRSS, PDF, GeoJSON, JPEG, GIF, SVG, PNG and more. In addition, one can edit data via the WFS transactional profile (WFS-T). GeoServer includes an integrated OpenLayers client for previewing data layers.
GeoServer additionally supports efficient publishing of geospatial data to Google Earth through the use of network links, using KML. Advanced features for Google Earth output include templates for customized pop-ups, time and height visualizations, and "super-overlays".
GeoServer relies on GeoTools, a GIS library.
