The intelligent vehicle monitor system based on GIS was experimentally studied. This paper describes the development of a new GIS library that is aimed at providing a rich and powerful environment for the development of GIS research. The motivation for this proposal is the current lack of either public or commercial GIS libraries that cater for the diversity of GIS data and algorithms, especially when viewed upon the latest advances in geographical information science. GIS library is open source software, allowing a collaborative environment and its use for the development of multiple GIS tools.
