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

Recently, the temperature in many parts of our country has soared all the way, ushering in 40 ℃ hot weather. Under the red high temperature warning, walking or cycling outdoors is really a kind of "roasting test". In the face of such hot weather, Amap announced the upgrade of "sunscreen navigation" and released the dynamic perception broadcast function on the shady section of the line. At the same time, sunscreen navigation will support the expansion of cities from 22 to 100, covering central and eastern South China (Liangguang) and southern China (Fujian, Jiangsu and Zhejiang). New areas of frequent high temperature early warning are added in the northern part of the northwest region (Urumqi and Turpan in Xinjiang) and the central and western part of Inner Mongolia (Hohhot).

It is understood that since its debut in the industry last year, Amap's "sunscreen navigation" has served more than 1.7 billion people.

Sunscreen navigation shade index (that is, the proportion of shaded roads) display

Compared with conventional cycling or walking navigation, the core feature of sunscreen navigation lies in the particularity of route planning variables: not only relatively static route planning should be taken into account. it is also necessary to combine more real-time dynamic "shadow" changes-which is crucial for more cyclists and walkers who are exposed to the summer sun.

Sunscreen navigation is on the basis of ensuring the rationality of the original planning, through remote sensing and dynamic light and shadow tracking and other technologies to intelligently recommend more routes covered by shadows around the road, in order to achieve the purpose of cool sunscreen.

When users use Amap for cycling or walking route planning, they can see shady routes in App, including "shade" and "Lou Yin" and other road sections; after this upgrade, when users are about to enter the shady section, Amap will automatically broadcast through voice to prompt users.

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 after this upgrade, Specific cities supported by sunscreen navigation include: the first batch of online cities Tianjin, Qingdao, Shijiazhuang, Zibo, Jining, Handan, Taian, Dalian, Foshan, Nanchang, Guiyang, Zhuhai, Wenzhou, Huizhou, Changzhou, Jiaxing, Zhongshan, Xuzhou, Shaoxing, Jinhua, Haikou, Nantong, Quanzhou, Yangzhou, Wuhu, Taizhou, Guilin, Sanya, Mianyang, Zhenjiang, Liuzhou, Hengyang, Ganzhou, Shantou, Huzhou, Jiangmen, Xiangyang, Xiangtan, Nanyang, Zhuzhou, Nanchong, Zhangzhou, Yibin, Deyang, Zhoukou, Turpan.

The second batch of cities will be launched in mid-July: Shenyang, Changchun, Taiyuan, Urumqi, Hohhot, Langfang, Luoyang, Baoding, Weifang, Xianyang, Linyi, Tangshan, Qinhuangdao, Cangzhou, Jinzhong, Taizhou, Rizhao, Zhaoqing, Yancheng, Datong, Huaian, Chuzhou, Bengbu, Heze, Zhanjiang, Anyang, Xingtai, Jiujiang, Zhangjiakou City, Qingyuan City, Yueyang City, Suqian City, Chenzhou City. More cities will gradually open up in the near future.

As a professional solution provider of digital map content, navigation and location services, Amap has always been committed to using scientific and technological innovation to turn various cutting-edge technologies into civilian services to provide users with a more high-quality and user-friendly travel experience. In the future, Amap will also continue to improve in the field of technology to better serve the travel of the majority of users.
