| 摘 要： | 遥感作为空间数据获取的一种手段,其在空间数据更新中的作用显得越来越重要,遥感数据已逐渐成为空间数据更新的主要数据来源。提出一种利用遥感图像自动更新GIS道路网络数据的方法,通过融合两种传感器图像数据,将整个道路网络准确完整地提取出来,然后通过线性特征的变化检测确定已修改的道路及新修建的道路。实验结果表明该方法可以准确地更新道路网络数据。

| Abstract: | Remote sensing,as a tool to obtain the spatial data,is becoming more and more important in the update of spatial data,and remote sensing data are becoming a main data source to update spatial data.A method is proposed in this paper to update road network in GIS automatically by use of the remote sensing imagery.The road network is extracted completely by fusing two kinds of sensor images,then the roads that are built newly or rebuilt are ascertained by change detection of linear features.The experimental result shows that the method can update the road network exactly. |
