Beschreibung
Zusammenfassung:	The invention provides a self-adaptive gridding distance calculation method and device, and the method comprises the following steps: 1, carrying out the gridding of a map according to the longitude and latitude, and determining the lengths and widths of all grids according to the business demands; step 2, carrying out data standardization on the longitude and the latitude, and then carrying out conversion on the length and the width; 3, determining longitudes and latitudes of four corners to which the grid belongs; 4, converting the actual longitude and latitude as the actual longitude and latitude of the central point of the affiliated grid; step 5, when the service system needs to obtain the navigation distance between two position nodes, converting the longitudes and latitudes of the two position nodes into the actual longitudes and latitudes of the central points of the grids to which the two position nodes belong according to the steps 1-4; and step 6, obtaining the navigation distance between the two p
