GeoServer is an Open Source application distributed under GPL license for the handling and dissemination of geospatial data. GeoServer provides the basic functionalities to create interoperable Spatial Data Infrastructures (SDI) according to standards edited by Open Geospatial Consortium (OGC) and ISO Technical Committee 211 (ISO TC 211). GeoServer has been created to ingest, manage and serve geospatial data both vector (called feature by OGC) and raster (called gridcoverage by OGC) as well as to create and disseminate georeferenced maps obtained by overlaying rendered versions of the above mentioned data according to styling rules coded following specific standards.
GeoServer has been developed to provide support for standard protocols to consitute a valid tool for the creation of distributed interoperable spatial data infrastructures (SDI). It natively supports a wide range of standards both edited by internally renowned bodies like OGC and ISO TC 211 as well as de facto like WMS-C, the protocol for the tile oriented access of Web Map Service or WMS (WMS).
