数字城市正射影像底图生产方法探讨

Discussion on the method for production of digital city orthophoto base map

以数字黄山1:1000正射影像图(DOM)生产实践为例,介绍了从空三加密、高精度DEM生成、影像纠正、镶嵌到分幅图出图的生产方法。

With the Huangshan 1：1000 digital orthophto map production as example,this paper introduced the process starting from aerial triangulation encryption,high precision DEM generation,image rectification,inlaying to output of mapsheet.
