摘要
以秦皇岛市航测1∶2000数字正射影像图(DOM)、数字高程模型(DEM)、数字线划图(DLG)项目为例,阐述了利用机载激光雷达(LIDAR)技术获取大比例尺数字高程模型(DEM)的方法,分析了应用实践中的一些问题,展望了今后的应用前景。
With the example of the 1:2 000 aerial phogrammetry item of Qinhuangdao producing Digital Orthophotography Model(IX)M), Digital Elevation Model(DEM) and Digital, this text relates the mothod to obtain a great scale of Digital Elevation Model(DEM), what make use of Light Detection And Ranging(LIDAR), analyzed some problems on the application practice and prospected the applied foreground for the future.
