Abstract

The invention discloses an industry address serial number generation method and device based on spatial grids. The method comprises the steps of carrying out the coding of map data, obtaining the spatial grids corresponding to the map data, and the spatial grids having spatial grid codes in one-to-one correspondence; calculating spatial grids corresponding to a plurality of longitude and latitudeinformation of the industry address data; obtaining a reference grid code through calculation, and a spatial grid corresponding to the reference grid code being located in the Kth layer of space hierarchy; judging whether the spatial grid code corresponding to the Nth longitude and latitude information is the same as the reference grid code or not, and if so, taking the spatial grid code as an industry address serial number of the industry address data; and if not, updating the grid code corresponding to the K-1th spatial hierarchy into the reference spatial code until industry address serialnumbers corresponding to all longitudes and latitudes in all industry address data are obtained. According to the embodiment of the invention, a large amount of floating point operation is not needed,and the generation efficiency of the industry address sequence number can be effectively improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and device for generating industry address serial numbers based on a spatial grid. Background technique [0002] The spatial grid refers to the regular division of the physical world according to the location distribution, altitude, and a certain interval size, and forms a grid covering the space in the virtual world mapped by the physical space. According to the grid spacing and division rules, the combination of spatial grids of different sizes also represents the physical world of different dimensions. The multi-dimensional spatial grid divides the virtual world into a series of multi-scale spatial grids, and codes each grid; The concept is to convert industry addresses into spatial grid codes and inherit industry data into grid space. In the existing industry address serial number generation method, the industry address is usually composed of the longitude and...
