topographty
1.The result shows that the method makes VCI and TCI more reasonable, considering the affection of cloud, topographty and the difference of temperature.
2.Topographty parameters and hydrological parameters extracted from DEMs are analyzed when DEM resolution is varied. The information content of different resolution DEM is quantified using entropy and analysis the sensitivity of hydrological parameters extracted from DEM to DEM entropy. Based on these analyses the effect of different DEM resolution on the runoff simulation and hydrologic parameter is analysis.
