High accuracy DEMs is an important data in study of soil erosion and terrain feature space analysis.Taking Nanxiaohegou watershed in Gansu Province
which is in the gully region of Loess Plateau as an example
and 1∶10000 relief map as an data source
the method of high accuracy DEMs and extract soil erosion index of watershed are discussed.The result shows that the terrain feature information is better and truly based on high accuracy DEMs
it is contented in the build of digital watershed at present.
