An effective cost distance calculation based on raster data model improved algorithm

Abstract: Abstract-In many applications of geographic information science, we often need to calculate the shortest path from the source point to the target points. Network data model can be computed using the graph theory algorithm, when faced with raster data model, the grid cells of raster will be treated as network model nodes in general, and the eight neighborhood unit of each grid cell will be treated as the direct neighbor nodes in network model. Some scholars have pointed out that this algorithm which network mod… Show more
