As economy booms 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 ihe cost of building the spatial database, 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 of towns, digitized surveyed maps and planned maps, and CAD data are available for this purpose. Firstly, CAD data is extracted and reclassified into layers according to Land Use Planning Database Standard for County; if CAD data is not available, maps can be changed into vector and then classified into different layers. Next, Quick Bird Image is used to complement and amend the layers, that is, to complement somewhere if it is still blank and to update somewhere if it already changed. Finally we render the layers with new color, symbols, linestyles or hatches. This solution is practical since data noted above can be acquired not only easily but in low cost; for example, up-to-date Quick Bird Image can be bought at the price of RMB 200-300 yuan/km~2 , Supermap GIS software is easy to use. We test our method for the Houshayu Town in Beijing. The results confirm the effectiveness of RS-based approach. It spares not only money but time since two workers can build such a database successfully in three weeks. |
