Abstract

The invention discloses an electronic map annotation display method, an annotation display device, electronic equipment and a computer readable storage medium. The method includes the steps: recordinga map annotation set displayed by an electronic map under proportional scales at all levels; increasing the weighted value of a certain map annotation in the map annotation set displayed under the proportional scale at a designated level if the map annotation in the map annotation set displayed under the proportional scale at the designated level is in a map annotation set displayed under a proportional scale at a previous level; displaying annotations selected from the corresponding map annotation set according to the weighted value of each map annotation in the map annotation set corresponding to the proportional scale under the current proportional scale of the electronic map. The map annotations are displayed by inheriting properties of the same map annotation under the proportional scales at different levels, and electronic map annotation display continuity is improved.

Description

technical field [0001] The present invention relates to the technical field of electronic maps, in particular to an electronic map annotation display method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Annotation refers to the labels and various text descriptions on the electronic map, and is an important part of the electronic map. In the outline of the electronic map, the ratio of the area occupied by all feature annotations to the total area is called annotation density. There is a limit to the annotation density, which can make the map difficult to read. [0003] In order to ensure that the annotation density in the electronic map is kept within a reasonable range in the map display of each scale, a part of the annotation is usually hidden in the map display of a larger scale. [0004] However, in the annotation display of electronic maps, important annotations need to be displayed from the small scale to the large s...
