Calculates the least-cost source for each cell based on the least accumulative cost over a cost surface, while accounting for surface distance along with horizontal and vertical cost factors. Legacy: This function is deprecated and will be removed in a future release. The Distance Allocation...
Each cell location value is multiplied by the cell resolution, and also compensates for diagonal movement to obtain the total cost of passing through the cell. The values of the Cost Raster can be integer or floating point, but they cannot be negative or zero. Path Type A keyword defining...
(x1,y1) are the absolute coordinates of the current point on the path, obtained from the last two parameters of the previous path command. rxandryare the radii of the ellipse (also known as its semi-major and semi-minor axes).
