Grid creation method and device, and distribution method and device

Abstract

Embodiments of the present disclosure provide a grid creation method and apparatus, and a distribution method and apparatus. The mesh building method comprises the following steps of: determining attribute information of a mesh geometric unit according to characteristics of a geographic region, and filling the geometric region with the mesh geometric units adjacent to each other; at least two meshes being obtained by dividing the geographic region composed of the mesh geometric elements adjacent to each other according to a preset mesh division rule; generating a mesh geometry cell identification of the mesh geometry cell and a mesh identification of the mesh; based on the mesh geometric unit identification of the mesh geometric unit and the mesh identification of the mesh, the corresponding relationship between the mesh geometric unit and the mesh being established, thereby saving the tedious operation of manually selecting points to construct a mesh, improving the efficiency of constructing a mesh, and saving a lot of labor costs. The mesh geometric unit identification of the mesh geometric unit and the mesh identification of the mesh are used to establish the corresponding relationship between the mesh geometric unit and the mesh. Moreover, each mesh geometric element is adjacent to each other, thus solving the problem that the mesh has gaps and providing a solution for 100%coverage of the business.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of geographic information, and in particular, to a method and device for establishing a grid and a method and device for distribution. Background technique [0002] In related technologies, dividing grids according to geographic regions is very useful in many fields, but the drawing of grids is mostly manually drawn on a map. Manually drawing the grid is not only inefficient, but also cannot guarantee that the area covered by the business can be 100% covered by the grid, which means that there will always be gaps between multiple grids drawn manually. Therefore, when delivery is performed using such a grid, the delivery area is also affected by the gap between the grids. [0003] In the solution in the related art, when dividing the grid according to the geographical area, the map is usually made into a webpage, and then manually select points on the webpage to form a grid using the selecte...
