To address this problem, the JCS Conflation Suite (JCS) set of tools was designed to address many common geospatial data integration problems, but at the same time take a pragmatic approach. With the development of the Java Topology Suite (JTS) and the advances in spatial reasoning, it is possible to create new tools that will support data integration in a robust, efficient, and repeatable fashion. JCS is being built on JTS.
The JCS tool suite operates independently of commercial software offerings. It will not support the native formats, but through transformation software available through GIS vendors or third parties, it will be realistic to use the JCS tools with typical geospatial data. In particular, JCS will make use of a constrained form of GML for all input and output.
