指出数字正射影像是利用像控点和数字高程模型，对影像同时进行倾斜改正和投影差改正，之后经影像镶嵌和匀光匀色后裁切而成。以大同市0．5m分辨率真彩色数字正射影像图制作项目为例，介绍了大同市勘察测绘院数字正射影像图的生产制作经验，以供类似项目参考借鉴。%This paper pointed out that digital orthophoto was the use of image control point and digital elevation model, at the same time made tilt correction and projection error correction to image, following cut by image mosaic and uniform light uniform color. Taking digital orthophoto map making project with 0.5 m resolution true color in Datong as an example, introduced the production experience of digital orthophoto map in Da- tong Surveying and Mapping Institute, in order to offer reference for similar project.
