Abstract

The invention discloses an electronic map route drawing method and device. In allusion to an overlong route, route data corresponding to a starting route segment of the route is parsed by a first parsing thread to obtain first parsing data, route drawing is performed by using the first parsing data through a drawing thread, the drawn route can be displayed in first time, the first parsing thread can be ensured not to be timed out in response through reasonably selecting the length of the starting route segment, and the waiting time of a user is reduced. Furthermore, route data corresponding tothe left route is parsed by using a second parsing thread to obtain second parsing data, the second parsing data is drawn and displayed by the drawing thread, thereby ensuring that the left route canalso be displayed.

Description

technical field [0001] The present application relates to the technical field of map drawing, and more specifically, to a method and device for drawing an electronic map route. Background technique [0002] When the electronic map client receives the user's navigation request, it will calculate the navigation route and obtain the route data corresponding to the navigation route. The route data includes road condition data, electronic eye data, traffic light data, etc. After the client obtains the route data, it will analyze it, use the analyzed data to draw the route, and finally display it. [0003] In the prior art, when analyzing and drawing route data, the main thread of the electronic map application is usually invoked to analyze the overall route data, and after all the analysis is completed, the route is drawn using the analyzed data. When the navigation route is too long, the amount of route data corresponding to the navigation route is huge, and the time it takes f...
