******* Library ******* The GeoTools library is organized into a series of jars. These jars form a software stack, each building on the services of the others. Individual jars such as ``gt-jdbc`` are extended with plugins in order to support additional capabilities. For ``gt-jdbc`` these plugins include support for common spatial databases such as ``gt-jdbc-postgis`` to support the PostGIS database. .. toctree:: :maxdepth: 1 api/index metadata/index referencing/index http/index main/index jts/index data/index coverage/index jdbc/index cql/index render/index xml/index Reference: * :doc:`../welcome/architecture`
