How to create least-cost path between two polygons with GRASS?
Geographic Information SystemsHow do you find the least-cost path? Least-cost path analysis. If the shortest path between any two points is a straight line, then the least-cost path is the path of least resistance. Least-cost path analyses use the cost weighted distance and direction surfaces for an area to determine a cost-effective route between a source and
