摘　　要：地形图动态更新是一项基础性测绘工作,是当前地形图图库一体和数据标准化应用的趋势。通过整合相关零星项目地形图成果资料,利用CAD、EPS、FME和ArcMap成图软件,叠加最新遥感影像并结合现场巡查,实现变化图斑从发现到实时更新,以保证地形图现状性的目的。结合各类成图软件的优点,构建空间索引,完成数据转换,做好接边和入库相关工作,是地形图更新和应用的有效实践。Dynamic updating of topographic map is a basic surveying and mapping work,which is the trend of integrating topographic map database and data standardization application.By integrating the topographic map results of relevant sporadic projects,using CAD,EPS,FME and ArcMap mapping software,superimposed the latest remote sensing image and combined with field inspection,the transformation map spots from discovery to real-time update were realized,so as to ensure the status quo of topographic maps.Combining the advantages of various mapping software,it is an effective practice for updating and applying topographic maps to construct spatial index,complete data conversion,and do well the related work of connecting edges and storing.
