The present application discloses a method for displaying an electronic map, an electronic device and a readable storage medium, and relates to the technical field of electronic maps, intelligent transportation, automatic driving, artificial intelligence technologies, etc. The specific implementation scheme is: after receiving a downsizing instruction from an electronic device, a server generates second map data under a second scale according to first map data under a first scale, and obtains third map data by repairing the second map data according to a neighboring relation of map elements, and the third map data is configured to eliminate a crack between adjacent map elements in the plurality of map elements contained in the second map data. After receiving the third map data, the electronic device renders and displays the electronic map in the second scale.
