    • Provided is a mesh data creation method allowing appropriate expression of population densities while making a balance between accuracy and granularity. In the mesh data creation method, when the number of samples in a region of reference mesh data with a predetermined size is not less than a threshold, divided mesh data is created by dividing the region of the reference mesh data. Namely, each portion with a high population density can be expressed by a fine region of mesh data and each portion with a low population density by a coarse region of mesh data. The above makes it feasible to prevent meshes from becoming too fine to ensure accuracy or, conversely, from becoming too coarse to maintain granularity, thereby resulting in failing to achieve a detailed grasp of population densities, and thus to achieve appropriate expression of population densities while making a balance between accuracy and granularity.
    • 提供了一种网格数据创建方法,允许适当表达人口密度,同时在精度和粒度之间取得平衡。 在网格数据创建方法中,当具有预定大小的参考网格数据区域中的采样数不小于阈值时,通过划分参考网格数据的区域来创建划分的网格数据。 也就是说,具有高人口密度的每个部分可以由网格数据的精细区域和具有低的人口密度的每个部分用网格数据的粗糙区域表示。 以上使得网格变得太细而不能确保准确性或相反地变得太粗糙以保持粒度,从而导致不能更好地掌握人口密度,从而实现人口密度的适当表达,同时 在精度和粒度之间取得平衡。
