Our country in the real estate industry to invest a lot of manpower, material and financial resources, real estate valuation industry plays an important role in the development of real estate industry.
The necessity and feasibility of introducing GIS in real estate appraisal The Geographic Information System (GIS) is the product of computer and geographical information science combined, widely used in various fields, such as resource management, city planning, environmental management, facility management, etc..
The establishment of the real estate in the actual appraisal information system's goal is to let the real estate information and related social and economic factors as the research object, the integrated use of methods and means of information science, system science and computer science, And a real estate evaluation as the main goal of integrated regional information system.
