Yang Kun · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2006
Based on a practical project and urban police professional work requirements, this paper has offered a solution for constructing the police spatial information decision support systems based on COM GIS technologies. According to the principles of software engineering, the systems development work contains the general system structure design, data requirements design, system function design, software interface design as well as the systems function realization methods. The main software technologies used in the systems development contain the spatial database, COM GIS, Web GIS, Oracle Objects for OLE (OO4O), and Police Decision Analysis Modeling technologies. In order to illustrate the basic principles and methods for the systems development, the realization process and relevant sample codes for crime case precaution function component has been described in the paper as an example for integrating GIS functions with police professional work models by using VC and VB developing tools. The realized systems function interfaces have also been offered in the paper for displaying the real effects of the systems. The development practice has proved that the COM GIS technology is very suitable for integrating police professional work models with GIS functions.
