摘要
最优路径分析是地理信息系统空间分析的重要技术之一,在理论和应用上有着广泛而深入的研究。结合土地利用外业调查的特点和要求,综合分析了复杂的地形情况,建立了代价函数的数学模型,并基于栅格数据,采用有序搜索算法实现最优路径搜索。
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.
