Problems solved by technology

In the current map, the coordinate transformation methods of different areas may be different. For example, the coordinates of some areas may need to be encrypted. Encryption will cause the coordinates to shift and deviate from the real coordinates. The coordinates of some areas may not require data. encryption
Due to the different coordinate transformation methods in different areas, it will easily cause coordinate mutation or coordinate overlap at the junction of different areas in the map

Abstract

The invention discloses a map coordinate processing method, a map coordinate processing device, electronic equipment and a storage medium, and relates to the technical field of maps. The map coordinate processing method comprises the following steps: acquiring geographic coordinates of a target position; determining map coordinates of the target position according to a relative position relationship between the geographic coordinates of the target position and a pre-generated buffer area boundary line, wherein the buffer area boundary line surrounds a first area, the first area is an area in which geographic coordinate and map coordinate transformation is carried out by adopting first coordinate transformation, and an area outside the buffer area boundary line is an area in which geographic coordinate and map coordinate transformation is carried out by adopting second coordinate transformation. According to the invention, the problem of coordinate mutation or coordinate overlapping atthe junctions of different regions in the map due to different coordinate transformation modes of different regions can be solved.

Description

technical field [0001] The present application relates to the field of map technology, and in particular to a method for processing map coordinates, a device for processing map coordinates, electronic equipment, and a storage medium. Background technique [0002] A coordinate system is a datum reference for representation of map data. In the current map, the coordinate transformation methods of different areas may be different. For example, the coordinates of some areas may need to be encrypted. Encryption will cause the coordinates to shift and deviate from the real coordinates. The coordinates of some areas may not require data. encryption. Due to the different coordinate transformation methods in different regions, it will easily cause the problem of coordinate mutation or coordinate overlap at the junction of different regions in the map. Contents of the invention [0003] The present application provides a map coordinate processing method, a map coordinate processin...
