Abstract

The embodiment of the invention discloses a road coding board configuration method and device of an electronic map, electronic equipment and a medium. The embodiment of the method comprises the stepsof integrating road lines in the electronic map to obtain a target road line; sampling the position of each road coding board in the target road line to obtain a sampling point; taking the obtained sampling points as sampling points corresponding to the highest display hierarchy of the electronic map, and sequentially selecting the sampling points corresponding to the next display hierarchy from the sampling points corresponding to each display hierarchy according to the descending order of the display hierarchies to obtain the sampling points corresponding to different display hierarchies; and based on the sampling points corresponding to the different display levels, configuring the road coding boards in the different display hierarchies of the electronic map. According to the embodiment, the stability of the display position of the road coding board and the map rendering efficiency in the electronic map zooming process are improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a method, device, electronic equipment and media for configuring road code plates on electronic maps. Background technique [0002] The content in the road code plate of the electronic map usually consists of letters and numbers. Letters are used to indicate the type of road (such as G for national roads, S for provincial roads, X for county roads, Y for township roads, and Z for exclusive roads), and numbers are used to indicate road numbers. In an electronic map, especially at a higher display level (that is, a smaller scale) of the electronic map, the road code plate can effectively indicate the position and direction, and provide convenience for users to travel. [0003] In the prior art, usually during the map rendering process, the position of the road code plate to be placed in the road line under the current display level is sampled in r...
