Designation And Implementation Of GIS Services Based On Sctipt

Interpreting system of GDL and GIS service creation environment designed for GIS services in general service platform is introduced in order to enhance the GIS ablility in the general service platform. The service provider can develop the GIS services through the platform.First, the thesis introduces the correlated technology and analyses the research status of the system. Then it introduces the OpenLS Core Services which is a criterion for describing Location Based Service. The GDL script language based on the above criterion has been designed. The designation of interpreting system and GIS service creation environment are based on GDL. This thesis also implements the graphic creation environment of GIS service-script. The testing of the system is covered.Finally, research and development results are summarized. Current problems for the system and future work are also mentioned.
