一种基于分界线的局部剖分网格与编码方法

A Method of Part Subdivision Grid and Coding Based on Boundary

针对当前地理空间剖分网格单元的地理距离无法精确,且网格编码类型单一问题,该文提出了一种基于经线以相等地理距离网格单元剖分地理空间,同时基于分界线动态计算网格编码的方法。实验表明,该方法能够满足对感兴趣的地理区域进行多尺度网格剖分,同时能够依据分界线位置生成不同类型编码。

In order to solve the problem that the geographic distance of the current geospatial grid cell cannot be accurate and lack of various coding type,this paper proposes a method of dividing geographic space by grid cell of the same geographic distance based on longitude,meanwhile,dynamically calculating grid codes based on boundary.The experimental results show that this method can not only satisfy multi scale dividing grid for the geographic region of interest,but also produce different type of codes based on boundary location.
