Abstract :
As economy is booming in China, the number of town grows rapidly. The rapid urbanization has brought many problems, such as the abuse of land development, the chaos of construction market, etc. Informationization based on GIS, RS and GPS is dedicated to this aid, that is, to build up geographical information system of planning and construction of town. However the biggest obstacle of informationization is the cost of building the spatial database, to which most of towns cannot afford. For this problem, by linking high-resolution remote sensing data, SuperMap GIS, and GPS, this paper proposes a workable solution. Quick Bird Image-a kind of high-resolution serves as main data source of spatial database, based on it CAD data or maps of planning and design of town are translated into predefined layers stored in spatial database by SuperMap GIS software, if there exists blanks, just digitize image into vector before screen. At last, a case study proves the above technological plan is a cost saving and fast one.
