This paper has introduced a popular method of combining map component with OOP language to develop Geographic Information System. This method has fully exerted the advantage of showing and processing geographic information with map component and the flexibility of the OOP. On the basis of the commerce and service census in Shanghai, we have developed Shanghai Commercial Geographical Information System (PC Version) adopting the ComGIS technology. This system is developed in the Visual Basic 6.0 environment embedded with the component MapObjects 2.1 of ESRI. Besides those basic GIS query and analysis function, this system has also been developed with the functions of the commercial circle mapping, the automatic positioning of commercial spot and the concentration analysis of commercial spots distribution, according to the character of the commercial management and analysis. This paper has elaborated on the function design, interface design and development technology of the system and summarizes its character.
