This document discusses GeoTools and GeoXTreme (GXT), open source geospatial toolkits. It provides information on: - GeoTools, an open source GIS toolkit for developing standards compliant solutions. It supports various data formats and can compose maps. - GXT, a commercial geoprocessing engine based on GeoTools that supports over 200 algorithms. GXT can be used for desktop or server applications. - Examples of GXT applications including the KOPSS GIS engine, KOPSS data mart tools, and education/personal uses of GXT and uDig.
