GeoServer
open-in-new
<h2 id="goals">Goals</h2> <p>GeoServer aims to operate as a node within a free and open <a href="/facts/Spatial_Data_Infrastructure/ByeqTux7">Spatial Data Infrastructure</a>. Just as the <a href="/facts/Apache_HTTP_Server/tcmWYYUq">Apache HTTP Server</a> has offered a free and open web server to publish <a href="/facts/HTML/sSc3fT78">HTML</a>, GeoServer aims to do the same for geospatial data. </p> <h2 id="features">Features</h2> <p>GeoServer reads a variety of data formats,<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> including: </p> <ul><li><a href="/facts/PostGIS/a3vdt50J">PostGIS</a></li> <li><a href="/facts/Oracle_Spatial/9EweByT4">Oracle Spatial</a></li> <li><a href="/facts/ArcSDE/Pdqtamd6">ArcSDE</a></li> <li><a href="/facts/IBM_Db2/2cYITuuY">IBM Db2</a></li> <li><a href="/facts/MySQL/QEEDNBDP">MySQL</a></li> <li><a href="/facts/MongoDB/9myQKGoY">MongoDB</a></li> <li><a href="/facts/Apache_Solr/2WrGtlx2">Apache Solr</a></li> <li><a href="/facts/Shapefile/mbCAeoFp">Shapefiles</a></li> <li><a href="/facts/GeoTIFF/l1TxVEM7">GeoTIFF</a></li> <li><a href="/facts/GTOPO30/Yns9RLa8">GTOPO30</a></li> <li><a href="/facts/ECW_(file_format)/JjMVlSmn">ECW</a>, <a href="/facts/MrSID/fJI3bBjh">MrSID</a></li> <li><a href="/facts/JPEG2000/GAzXdHI2">JPEG2000</a></li></ul> <p>Through standard protocols it produces <a href="/facts/Keyhole_Markup_Language/6L7da3xC">KML</a>, <a href="/facts/Geography_Markup_Language/IEMlqp0s">GML</a>, Shapefile, <a href="/facts/GeoRSS/EGuAkakN">GeoRSS</a>, <a href="/facts/Portable_Document_Format/C9Mn1vYL">PDF</a>, <a href="/facts/GeoJSON/IcBNDHNL">GeoJSON</a>, <a href="/facts/JPEG/HQ8QS3uB">JPEG</a>, <a href="/facts/GIF/HfIBWrIC">GIF</a>, <a href="/facts/Scalable_Vector_Graphics/ARq5C3YV">SVG</a>, <a href="/facts/Portable_Network_Graphics/mwgK6xw5">PNG</a> and more. In addition, one can edit data via the <a href="/facts/Web_Feature_Service/kwh86hzn">WFS transactional profile</a> (WFS-T).<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> GeoServer includes an integrated <a href="/facts/OpenLayers/mfAftuJ9">OpenLayers</a> client for previewing data layers. </p><p>GeoServer additionally supports efficient publishing of geospatial data to <a href="/facts/Google_Earth/jjJmIjmb">Google Earth</a> 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". </p><p>GeoServer relies on <a href="/facts/GeoTools/jSEFLIX5">GeoTools</a>, a <a href="/facts/Geographic_information_system/PoP1kVoa">GIS</a> library.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p> <h2 id="usage">Usage</h2> <ul><li>MassGIS (Massachusetts state GIS)</li> <li>MACRIS Maps (Massachusetts Historical Commission)</li> <li><a href="/facts/TriMet/1KIk5sQx">TriMet</a> (Transit agency for Portland, Oregon)</li> <li><a href="/facts/Ordnance_Survey/syLosef7">Ordnance Survey</a> (National Mapping Agency of the UK)</li> <li><a href="/facts/Institut_G%25C3%25A9ographique_National/lTovz0Se">Institut Géographique National</a> (National Mapping Agency of France)</li> <li><a href="/facts/GBIF/oalM9el2">GBIF</a> (Global Biodiversity Information Facility)</li> <li><a href="/facts/World_Bank/hIH9uUb2">World Bank</a></li> <li><a href="/facts/Global_Earthquake_Model/EF87JPPy">Global Earthquake Model</a></li> <li>GMOS (Global Mercury Observation System)</li> <li><a href="/facts/FAO/13WV8JJK">FAO</a> (Food and Agriculture Organization of the United Nations)</li> <li><a href="/facts/New_York_City_Department_of_Information_Technology_and_Telecommunications/PmdaHcWK">New York City Department of Information Technology and Telecommunications</a></li> <li>TeamSurv</li> <li><a href="/facts/International_Telecommunication_Union/Yn8UKKkw">ITU</a> (International Telecommunication Union)</li></ul> <h2 id="architecture">Architecture</h2> <p>GeoServer uses the <a href="/facts/Spring_Framework/ajIwLM73">Spring Framework</a>, providing a request dispatch architecture for modules implementing OGC services. The web administration application uses wicket, allowing extensions to contribute additional configuration screens. The application provides a REST API implemented using the <a href="/facts/Spring_Framework/ajIwLM73">spring-mvc-framework</a>. </p><p>GeoServer is a web application, supporting any common <a href="/facts/Java_Servlet/hf5LQVq1">servlet container</a> (a standalone distribution is available with the <a href="/facts/Jetty_(web_server)/QI8x2ooX">Jetty (web server)</a> as an embedded server). GeoWebCache, a Java-based caching component similar to TileCache, is bundled with GeoServer, but available separately.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> Similarly, GeoServer packages GeoTools as a Java library, but it is also available separately.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p><p>GeoServer is a longstanding application and has undergone several architectural changes. GeoServer 1.0 was built around the STRUTS framework, with the migration to Spring and Wicket taking place for GeoServer 2.0. Early versions of the REST API used restlet before migration to <a href="/facts/Spring_Framework/ajIwLM73">spring-mvc-framework</a>. </p> <h2 id="see-also">See also</h2> <ul> <li>Free and open-source software portal</li></ul> <ul><li><a href="/facts/Open_Geospatial_Consortium/uDKbX6Cl">Open Geospatial Consortium</a></li> <li><a href="/facts/Web_Feature_Service/kwh86hzn">Web Feature Service</a></li> <li><a href="/facts/Web_Map_Service/QY1uaIbk">Web Map Service</a></li> <li><a href="/facts/Web_Coverage_Service/5qnKgpkl">Web Coverage Service</a></li> <li><a href="/facts/MapServer/InTeCf0j">MapServer</a> - an open-source server written in C</li> <li><a href="/facts/Mapnik/2AV99gWz">Mapnik</a></li></ul> <h2 id="external-links">External links</h2> <ul><li><a href="https://geoserver.org/">Official website</a> </li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"GeoServer". geoserver.org.
