Abstract

The invention provides a geographic grid division method, a business district determination method and equipment. The geographic grid division method comprises the following steps: determining a geographic transformation operator according to the size of the geographic grids to be divided and a predetermined relationship between the size of the geographic grids and the geographic transformation operator; respectively carrying out predetermined mathematical operation on the longitude and latitude of the point in the predetermined area and the geographical transformation operator, wherein the predetermined relationship and the predetermined mathematical operation enable the longitude codes and the latitude codes corresponding to the points in the predetermined region to be continuously changed along with the continuous change of the size of the geographic grid; and dividing the points with the same longitude codes and latitude codes in the predetermined area into the same geographic grid. According to the embodiment of the invention, the geographic grid division method can achieve the continuous adjustment of the geographical range precision of the business district.

Description

technical field [0001] The embodiment of the present application relates to the field of computer and communication technology, and specifically relates to a method for dividing a geographical grid, a method for determining a business district, a device, and a computer-readable storage medium. Background technique [0002] The geographical scope of business circles has very important commercial value and is the basic geographic data required for offline business operations. The determination of the geographic scope of business districts is mainly divided into two types: manual mapping and automatic algorithm mining. Manual drawing requires manual drawing of the geographical range of business districts on the map based on one’s own understanding, which needs to be drawn one by one, which is inefficient and consumes a lot of manpower and material resources. Algorithm-based mining is based on the collected geographic data, and an algorithm program is designed to automatically ...
