CTOnews.com August 25 news, the recent continuous hot weather for users to travel, especially more cycling, walking users, is undoubtedly a major problem. Amap recently launched "sunscreen navigation" for cyclists and pedestrians, using dynamic light and shadow tracking technology to calculate the shadow area of roads covered in a specific period of time in real time to provide users with a cooler travel experience.

According to official introduction, this Gaode online sunscreen navigation is to intelligently recommend more routes covered by shadows around the road for users through remote sensing and dynamic light and shadow tracking technology on the basis of ensuring the rationality of the original planning. in order to achieve the purpose of cool sunscreen.

CTOnews.com learned that when users use Amap for cycling or walking route planning, they will be able to see shady routes in App, including "shade" and "Lou Yin".

Among them, the tree-lined road section is Gao de through the principle of remote sensing technology, intelligently identify the distribution density of trees around the road, synthesize the specific geographical location and other factors, calculate the dynamic light and shadow status of the road section, so as to achieve the purpose of recommendation for users.

On the other hand, the judgment of Louyin road section is more complex, which involves many factors, such as building position, height, shape, road width, and even the specific orientation of the sun in different time periods, exposure angle and so on. for this reason, Gaode designed a set of dynamic light and shadow tracking algorithm, which can integrate various factors to calculate the shadow coverage area of a certain road section and whether it meets the conditions, so that it can be marked as the Louyin road section for users.

It is understood that the first phase of Gaode sunscreen navigation has been launched in 22 cities such as Beijing, Shanghai, Guangzhou, Shenzhen, Hangzhou, Chengdu, Chongqing, Xi'an, Wuhan, Changsha, Zhengzhou, Suzhou, Nanjing, Hefei, Kunming, Jinan, Dongguan, Ningbo, Nanning, Fuzhou, Wuxi and Xiamen. From now on, users in the above cities only need to upgrade Amap's App to the latest version to experience sunscreen navigation.
