Design And Implementation Of Real Estate Registration And Transaction Based On The GIS

In recent years, realty is becoming more and more the heart of people’s expenditure and investment. People have no longer been satisfied with the traditional artificial management model. Therefore, it is necessary to establish a quick and convenient intelligent management model, which may supply the users with the realty information for browse, query and evaluation. This paper combines the strong GIS software (ArcGIS) with specific realty practice, uses the method of VB+AO to carry out second exploitation, and uses ORACLE database to manage large realty data. It aims to enlarge the basic construction of the house property right management, enlarge the depth of the house right management, and realize the comprehensive efficient management and use of the house property figure data and attributive data by establishing the GIS house drawing and text information system. The system aims to achieve the non-paper, computerized and scientific management of house right and right trade, and on the basis of that to establish the realty trade management information system and the realty price index system in the future, to serve statistical analysis and decision making, and to improve the quality level and efficiency of the market management of house right.This paper mainly studies the following contents:1. building an ArcGIS runtime environment that consists of the hardware environment and the software support environment;2. using city’s construction planning map (CAD drawings) to build a complete administrative region in ArcMap, and developing again based on the ArcGIS for generating property table associated with the application of MapSurvey positioning system;3. deriving house table from the new project outcomes (Floor and House Map) obtained by the mapping system, and associating it with a general assembly drawing by locating using MapSurvey (old project outcomes should be divided into registration units according to the standards of Surveying and Mapping Division, and then the Floor and House Map can be extracted).4. developing and improving the housing registration and transaction management system according to the requirements of housing registration measures made by housing construction department.Eventually the realty trade management information system was built by adopting GIS (Geographic Information System) and Data Warehouse (data warehouse) as the core technology, integrating the various types of real estate business and data, and fully absorbing and making use of the original system’s experience and data, to achieve the comprehensive management of service information and figures. Through the establishment of real estate data warehouse to complete all kinds of data processing, comprehensive analysis and multi channel release, important information and basis is provided for decision-making, management, and property investment of polloi.
