COMGIS does not depend on which program language is used,in which the function of GIS is completed by the GIS's OCX and the special function can be accomplished by developing on or embedding special OCX in General Visual Development Environment(such as VC,VB and Delphi). Now, COMGIS becomes a chief development model of GIS. COMGIS integrates GIS with the special model so closely that it can accomplish not only the function of GIS but also the function of the special application. This paper illuminates the basic concept and technology of COMGIS and introduces the ESRI's OCX named MapObjects in detail. Furthermore, it discusses the design and development process of the Underwater Resource Spatial Analyze System based on COM technology.
