城镇基准地价评估成果管理信息系统

Evaluated Result Management Information System of Standard Land-Value in Cities and Towns

目前,各城镇一般选择AutoCAD和Excel对基准地价评估成果图和成果表分别管理,这种管理主要问题表现为:数据更新效率低;图与表数据不一致性;数据分析和图表双向查询困难;结果输出形式单一等。系统改用MapInfo系统软件基础平台,建立评估成果空间数据库,利用组件开发方式,建立基准地价评估成果管理信息系统。该系统通过文档管理、成果图表管理和GIS专题子系统集评估成果图、表、文于一体,实现了对成果信息的图形操作、属性管理、信息查询、空间分析和专题制图等,保证了地价评估成果图、表数据显示和更新的一致性,图件编制、数据维护和信息分析更加直观、简单,改善了原有基准地价评估成果管理现状,提高了基准地价评估成果管理水平。

The evaluated results of standard land-value in cities and towns are managed presently with AutoCAD and Excel individually, maps with AutoCAD and tables with Excel. This kind of management lowers data renewal efficiency, brings inconsistency between maps and tables, and makes data analysis and bidirectional inquiry between maps and tables difficult. On the basis of management present situation and open questions, the study introduces the GIS technology by selecting Maplnfo Geographic Information System software platform, and establishes standard land-value evaluated results management information system by the way of component development which integrates the evaluated results maps, tables and documents. The system, based on map and attribute database, includes four sub-systems such as document management, map management, table management and GIS topic analysis. The output results are given by five modules such as map operation, attribute management, spatial analysis, information inquiry and output mapping in its function. The system applications demonstrate that it is convenient for map locating, attribute analyzing, historical data reproducing and thematic mapping by using GIS to man-age standard land-value evaluated result. At the same time, it can guarantee the displaying and renewal consistency between maps and tables, and make data maintenance and analysis easier. So the system can improve the management of standard land-value evaluated results.
