基于3S技术的土地利用巡查系统研究

Research on land use visitation system based on GPS/RS/GIS

针对传统土地资源调查周期长、精度低、现势性差的问题,本文提出一种基于3S技术的土地利用巡查方法,并利用组件式GIS开发技术、空间数据拓扑分析技术、多源数据集成技术、软件系统集成技术等先进技术开发完成了土地利用巡查系统,并在东南大学和天津市北辰区进行了试验,基本满足实际应用需求,为土地利用巡查提供了一种新的方法,解决了传统土地资源巡查过程中的问题。

According to the problem of long period, low accuracy and slow updating for land resource survey, a new method of land use inspection has been brought forward based on GPS/RS/GIS. And the land use visitation system has been developed and tested to meet basic needs of practical applications in Southeast University and Tianjin BeiChen District on the basis of ComGIS development technology, spatial clara topological analysis technology, multi-source data integration technology, software integration technology and other advanced technology. This system provides a new method to solve the traditional land resource problems in the inspection process.
