| Abstract: | This paper introduced the principle of GPS-supported aerotiangulation.Using SWDC digital photographic,we analyzed different schemes of GPS-supported aerotriangulation.It proved to be true that dividing aerotriangulation area in specifications for GPS-supported aerial photography that was reference to the similar projects.What's more,we proposed some logical suggestions which could be valuable for the surveying works. |
