Develop A System Of GIS Based Query And Monitoring For The Land Utilization Profile Of Hangzhou

The rapid development of GIS technology has created applications in almost every industry. Methods for studying urban land utilization include numerous geographical analysis information processing. This has become one of the most important and unique applications in the field of GIS.With a major reform in the housing system in China, the market mechanism is turning into the basic means to allocate and control real estate. Some developers take full advantage of analysing the relation between market supply and demand to help investment and marketing decision, and using the demand information asymmetry, by engaging in unethical and even illegal activities such as delaying a delivery date to increase profits. Government sector should analyse the relationship between demand and supply, rationally determine the supply of the land, aviod the status like serious supply exceeds demand or Supply falls short of demand. While some local governments supply the land only in accordance with the demand of developers, it caused periodically shortage or over supply of the commercial residential building. In order to in the gripe of the market demand all-around, it is particularly important to develop a GIS-based urban land utilization system for Hangzhou city that supports advanced dynamic tracking and inquiries.This system will utilize a database for the city of Hangzhou that includes information such as land lease, examine and approve the planning permissions and builder's licences, and sales status. This system will then produce a completed file of demand analysis. This system is based on UML modeling, using MapX components, and established functions such as map indication and various enquiry paths in a VB context, it provides an efficiency tool for grasping the development of the land have been put in sales status and space distribution of Hangzhou thought correctly.
