| Abstract: | The most optimal path analysis is an important technology in the spatial analysis .It has been widely and deeply studied both in theories and practices. In this paper, the author accorded to the features and requires of field investigation in land use survey, and analyzed the intricate terrain in field investigation, established a mathematical model of the cost_function, then based on the raster map, with the ordered search algorithm realized the search of the most optimal path of orienteering. |
