DEM分辨率对地形因子提取影响的研究
Study on the Effect of DEM Resolutions Extracting on the Landform Factors
摘要
Abstract
The 1:50000 contours data of Mohe area Daxingan Mountains was used as the objective to generate different resolution Digital Elevation Model (DEM) and analyze the changes of slope,aspect and profile curvature under condition of the different resolution DEM.The change trend of DEM height-entropy with different resolution was also analyzed.The results showed that the changes of each topography factor became stable when the DEM resolution came to around 25 meters and the change became apparently intensive when the resolution came to over 50 meters.Height-entropy changed slowly when the resolution enlarged to 25 meters.It was concluded from above results that the most appropriate resolution should be 25 meters in the Mohe area when 1:50,000 contours was used to generate DEM.关键词
