Euclidean Distance with Weighted Values
Geographic Information SystemsWhat is the meaning of weighted Euclidean distance? The weighted Euclidean distance measure between row (or column) profiles of a table, where each squared difference between profile elements is divided by the corresponding element of the average profile. What is the formula for weighted distance? The distance-weighted mean is: DWM=w1x1+w2x2+w3x3+w4x4w1+w2+w3+w4≈7.3. How do you calculate Euclidean
