Hi Stephanie, If you would like to calculate from a set of 5 points the least cost path between each pair of points, you shoud create cost distance rasters for each point. So we're talking about 1 calculation for each point (5 in total). Then for point 1 you take the cost distance raster and the 4 other points to calculate the 4 paths. For point number 2 you take points 3, 4 and 5 and calculate the paths. For point number 3 take points 4 and 5 en for point 4 take point 5. I do not see a faster way since to determine the path to a source you will need the cost distance raster specifically for that source. Kind regards, Xander Hi again, thanks for the response. - Stephanie
