摘要：This paper deals with inherent error analysis of slope variable due to the IDW interpolation method and it’s various power values. In the first section it shows slope analysis method and algorithm. In the second section it creates a DEM model from various measured and erroneous elevated points which becomes input to calculate slope of interpolated DEMs separately then error is calculated by calculating difference of the slope for measured and erroneous slope. It explores error analysis of slope with its practical implementation in ArcGIS. In the last section it explains the comparison of errors for various power of IDW method. This paper demonstrates that slope error increases with the increment in the inverse power of distance in IDW method.
