| Abstract: | DOM is an important part of the 4D products, but there are many factors affecting the accuracy of the DOM in the production process. In the paper, the affected factors of the DOM plane accuracy are analyzed from the system errors of image point coordinates, the accuracy and projection errors of Aerial Triangulation products and the DEM data errors. The corrected methods about these errors are introduced briefly. |
