摘要
数字高程模型是数字地球技术和各种数字化模型的重要基础 ,目前已有多种DEM生成技术 ,以全数字摄影测量方法最具前途。本文介绍了利用OEAD(OrthoEngineAirphotoDEM)软件进行DEM提取的方法和技术流程 ,以某水库库区金龙山地区为例进行了DEM提取 。
DEM (Digital Elevation Model) is the most important basis of the Digital Earth model and other digital models. There are many methods to obtain it. This paper discusses the technique and procedure of DEM extraction by using airphotoes under OEAD platform? An example of DEM extraction for Jinlong Mountain is given, and some problems existent in DEM extraction are discussed.
