| 摘 要： | 建立了一套基于遥感信息和DSM的变化检测信息管理系统,该系统主要包括DSM数据管理模块、DSM变化检测模块和变化结果表达模块。系统利用多时相的数字表面模型(DSM),通过变化检测模块检测出城市地区人工建筑物、植被等的变化情况,检测结果可以应用在基本农田保护、土地利用变化监测以及违法用地查处等方面,为地理国(市)情监测提供技术支持。检测过程自动化程度高、快速、准确。

| Abstract: | The paper establishes a change detection information management system based on remote sensing information and DSM.This system mainly consists of three important parts: DSM data management module,change detection module and visualization module.It detects the changes of artificial buildings and vegetation through the multi-temporal digital surface model.The change detection results can be used in the areas of basic farmland protection,land use change monitoring,illegal use of land,and etc.And it provides technical support for national or urban geographic condition monitoring further.The method is highly automatic,rapid and accurate. |
