The Further Study on the Accuracy of DEM Terrain Representation

WANG Guang-xia~1, ZHU Chang-qing~(1,2), SHI Wen-zhong~3, ZHANG Guo-qin~2(1. Zhengzhou Institute of Surveying and Mapping, Zhengzhou 450052, China; 2.Institute of Geodesy and Geophysics, Chinese Academy of Science, Wuhan 430077, China; 3. Advanced Research Centre for Spatial Information Technology, Department of Land Surveying and Geo-Informatics, The Hongkong Polytechnic University, Hong Kong,China)  
The relation between DEM terrain representation error (E_t) and the variation of DEM resolution (R) and mean profile curvature (V) is studied. And a new formula on the relation for RMS E_t, R and V is described as: RMSE_t=(0.006 1V+0.002 7)R+0.001 0V~2-0.064 9V+0.569 5On the other hand, a formula on the relation for RMS E_t, R and slope W is described as: RMSE_t=(0.000 1W~2+0.003 1W+0.030 1)R+0.000 8W~2-0.050 8W+0.355 9The analysis of the formulae shows that there is high accuracy by the developed formulae.
