What are the differences in the various residual distribution methods?
Summary on the Use of Distribution of Residuals in Coordinate Transformations: 1.0 Main Purpose on the Use of Residual Distribution in Coordinate Transformations: The spatial distribution of residuals can be applied to estimate additional shifts to the transformed coordinates. Known coordinates can be matched exactly whereas other coordinates are slightly shifted from the spatial distribution of residuals within the transformation area. These shifts can be determined from different Distance Weighting or Multi-Quadratic Interpolation methods of residuals. 2.0 Two Methods of Residual Interpolation: 2.1 Distance Weighting Residual Interpolation Method: The Distance Weighting Residual Interpolation Method uses 3 distance weighting schemes namely: – 1/Distance – 1/Distance**1.5 – 1/Distance **2.0 The main purpose of the distance weighting interpolation method is to de-correlate slowly (1/Distance), moderately (1/Distance**1.5) or rapidly (1/Distance**2.0) the influence of residuals at the p
