Uncertainty and effects of resolution of digital elevation model and its derived Features: case study of Sumberjaya, Sumatra, Indonesia uri icon

abstract

  • Hydrological and erosion studies rely heavily on the information of slopes and other topographic features commonly derived from DEM. How reliable is the information while assessing using true values of geospatial information is quite problematic? Attempts to assess the uncertainty, as an estimate of error, using statistical approach and to find optimum spatial resolutions for the DEM in different types of terrains are presented in this work
