Research on Error of Derived Slope and Aspect Related to DEM Data Properties

LIU Xue-jun1,4,GONG Jian-ya2,ZHOU Qi-ming3,TANG Guo-an1(1.College of Geographical Sciences,Nanjing Normal University,Nanjing 210097;2.National Key Laboratory for Information Engineering in Surveying,Mapping and Remote Sensing,Wuhan University,Wuhan 430079; 3.Department of Geography,Hong Kong Baptist University,Hong Kong;4.College of Road Engineering,Changsha Technology and Science University,Changsha 410076,China)  
Today digital elevation data have been commonly provided in grid data structure,so that the term DEM has been widely regarded as digital elevation grid.The DEM data properties such as resolution,orientation and data precision have effect on slope and aspect derived from DEM.This paper studies the relationship between DEM data properties and slope and aspect by theories and data-independent DEM error analysis.The findings of this study can be summarized as:1)High resolution DEM does not assure high accuracy of slope and aspect.2)Appropriate DEM resolution(g)may be expressed by RMSE of DEM(m),RMSE of slope(mS)and DEM mean slope(S),g=bm/ms×180/π×cos2 S,in which b is coefficient of data error of slope algorithms.3) Grid orientation does cause directional bias on derived slope and aspect,and the third-order finite difference algorithm series,which encompass 3rd order finite difference,3rd order finite difference weighted by reciprocal of squared distance and 3rd order finite difference weighted by reciprocal of distance,have shown the most significant errors due to the change of grid orientation.
