Shulou(Shulou.com)11/24 Report--

On February 10, Amap announced the launch of a "confession route" function based on the grid route planning algorithm, which can recommend nearby routes for users, so that users can mark the shape of "CTOnews.com" or "love" on the map by walking or cycling.

Amap said that in conventional route planning, the algorithm considers factors such as time, distance, and whether it is easy to walk, while graphic route planning tests the accuracy of the algorithm and the system's ability to understand graphics. In addition, the algorithm also needs to identify and find paths similar to the given graphic height in the map, in order to avoid "connecting strokes" or "lack of strokes" as far as possible, we should also consider many factors, such as turning, U-turn, whether the route must be repeated or not.

The core of Amap's graphic route planning function is the grid-based route planning algorithm (Grid based route planning, GBRP). The system analyzes the road network by grid, and then uses these grids to calculate the text or graphics with flat edges.

CTOnews.com learned that the "confession route" function launched this time is based on the research and development of Amap's sports route function, and users can also search the keyword "sports route" on Amap's home page to see the urban sports route suitable for running or cycling.

At present, Amap's "sports route" has covered Beijing, Chengdu, Hangzhou, Qingdao, Shanghai, Suzhou, Xi'an, Zhengzhou, Tianjin and other cities, including more than 3800 urban greenways. In addition, there are other theme cycling routes recommended by users in some cities, such as "Beijing Hutong cycling route", "Beijing ancient biking route" and so on.
