土地利用变更分析与管理系统设计与实现——以SuperMap Objects软件应用为例

Design and reliazation of land use change analysis and manage system based on SuperMap Objects

GPS/PDA技术应用于土地利用变更调查可实现全数字化外业采集,为达到外业采集数据与土地利用现状数据库的无缝衔接,需设计内业GIS系统完成数据处理与报表输出。本文研究了变更分析、图斑自动标注等关键技术,设计了基于SuperMap Objects(超图)的土地利用变更调查分析与管理系统,实现了图斑的变更分析与处理,图件自动更新,自动输出变更记录表等功能。系统应用表明能够满足土地利用变更调查的业务需求。

GPS/PDA technology could realize all-digital outside information gathering in land use change survey,in order to link up the data gathering outside and the land use actuality database,a GIS system to complete the data processing and the excel reporting should be designed.This article has studied some key technologies,such as the change analysis,chart spot automatic labeling and so on.A land use change analysis and manage system based on SuperMap Objects has been designed.It realizes the change analysis and process of the chart spot,the automatic graphic document update,the automatic change report output and so on.The system application indicated that this system can meet the demand of land use change survey.
