GeoServer

Overview of the GeoServer architecture

The GeoServer application is comprised of a series of modules. GeoServer modules can be combined with maven to form a deployable war.

At runtime a module can make use of Spring to obtain classes providing services from other modules. This ability to "plug-in" additional functionality forms the basis for GeoServers extension mechanism. This mechanism is used to provide additional OGC web services (by the WFS and WMS modules) and to implement support for different WMS image encodings.

Features

GeoServer reads a variety of data formats, including PostGIS , Oracle Spatial, ArcSDE , DB2, MySQL , Shapefiles, GeoTIFF , GTOPO30 and a variety of others.

It also produces KML, GML, Shapefile, GeoRSS, Portable Document Format, GeoJSON , JPEG, GIF, SVG, PNG and more.
