Zusammenfassung: | The embodiment of the invention provides a geographic entity coding method and device, computer equipment and a medium, and relates to the technical field of data processing.The method comprises the steps that in a map of a preset area, all geographic entities are abstracted into vector diagrams; in the map, calculating a first position of the region map of the key sensitive point, and calculating a second position of the vector diagram of each geographic entity; calculating the distance between each geographic entity and the key sensitive point according to each second position and the first position; encoding the region graph of the key sensitive points to obtain key sensitive point codes; encoding each distance to obtain a distance code corresponding to each geographic entity; and coding each geographic entity according to the key sensitive point codes and the distance codes corresponding to each geographic entity. According to the scheme, the codes of each geographic entity comprise the key sensitive poin |
