The GeoServer Project - the open Internet gateway for geographic data
The GeoServer Project is a Java (J2EE) implementation of:
- The OpenGIS Consortium's Web Feature Server specification. With full transactional support!
- The OpenGIS Consortium's Web Map Server Specification.
- ZServer
GeoServer is free software, available under the GPL 2.0 license.
Users who would like to access and modify their geographic data over the Internet using flexible, industry-approved standards should take a look at GeoServer.
GeoServer Design
GeoServer is constructed using a Layered Design as outlined in the diagram below. There are two Layer systems in use - the classic J2EE Servlet/Handler/Request/Response and the STRUTS Framework.
GeoServer Layer Diagram
Use of GeoTools2
As seen in the above Layer Diagram GeoServer makes use of the wonderful GeoTools2 library to provide data access. GeoServer maintains its own geotools.jar available in the lib directory. This jar is often more recent then the latest GeoTools public beta.
Many GeoServer classes implement GeoTools2 interfaces inorder to facilitate reuse and intergration with subsystems such as validation.
