On May 31, Gaode Map announced that it has reached a strategic cooperation with the China Meteorological Administration Public Weather Service Center. The two sides will conduct in-depth cooperation in weather warning and big data sharing. After accessing the authoritative and refined meteorological data of the China Meteorological Administration, Gaode Map can provide users with intelligent weather services based on location and travel cycle.
The reporter also learned that before the arrival of the national main flood season, the two sides also cooperated to launch the AI ​​version of the Sekisui map. With the help of big data, artificial intelligence and other scientific means, real-time prediction of urban road water accumulation points in the event of bad weather, and The affected people will promptly remind and travel to help people to travel safely during the flood season and reduce unnecessary injuries and losses. The AI ​​version of Sekisui Map will first be launched in 17 cities including Shenzhen, Guangzhou, Wuhan, Nanjing, Zhengzhou and Changsha, and will cover more cities across the country.
Strong cooperation to provide more accurate weather services
Meteorology and travel are both rigid needs in people's lives, and they are highly correlated. The Public Weather Service Center is affiliated to the China Meteorological Administration and has the most authoritative weather information in China. The Gaode Map is the largest mobile travel platform in China.
Li Haisheng, deputy director of the Public Meteorological Service Center of the China Meteorological Administration, said: "By establishing strategic cooperation and promoting the sharing of resources between meteorological big data and traffic big data, the two sides can combine meteorological information with users' location and travel routes to provide more timely access to the public. More accurate and more stereoscopic weather forecasting and warning services to enhance the effectiveness of disaster prevention and mitigation."
Traditional meteorological information services are mostly passive acquisition methods, and the phenomenon of information lag is more serious. Moreover, the basic information obtained by people is urban-wide meteorological information, which is not fine enough in terms of granularity. The high-tech map has a natural LBS (Location Based Service) attribute. After accessing the authoritative data of the China Meteorological Administration, it can provide users with their current location, designated POI location and more accurate weather information services based on travel routes. In addition, the high-tech map can provide weather services including travel decisions, travel planning, travel navigation, destinations and other travel cycles.
Map the real world to the map
At the same time, the China Meteorological Administration's Public Meteorological Service Center and Gaode Map also issued a AI version of the Sekisui Map for the flood season.
During the flood season every year, due to the lack of timely warning information, urban floods and roads will cause a lot of personal injury or property damage to the people. However, since road water accumulation is affected by many factors such as meteorology, roads, drainage, and transportation, real-time warning has been a problem in the past, and there are often many shortcomings in terms of accuracy, timeliness and coverage.
The AI ​​version of the Sekisui Map attempts to use the big data and artificial intelligence technology to solve this problem. According to reports, Gao De established a model of machine learning, inputting the authoritative and refined real-time and historical meteorological data provided by the China Meteorological Administration, and combining the road big data, traffic big data and historical easy points inherent in Gaode. Data, user UGC (user-originated content) report data, etc., according to the algorithm model for data analysis and mining.
When bad weather occurs, the model can intelligently and timely predict the serious road water accumulation points in the city and generate water accumulation events on the Gaode map. Finally, each water accumulation event will have a large number of high-definition users to verify the credibility, and then improve the accuracy of the water accumulation information.
When the user sees the water accumulation incident, he can avoid this road section in advance to avoid road congestion or vehicle wading. If the user does not notice the water accumulation information, the Gaode map can also promptly remind the travel users who may be affected in various ways, and help them avoid the relevant wading sections in time for travel planning and navigation.
It is understood that Gaode traffic and road big data have covered more than 360 cities and all highways nationwide, accumulating 8.2 million kilometers of navigation road data, and only 400 road attribute information. In addition, Gaode also has easy-to-point data for most cities in the country, and users report hundreds of thousands of water events every year.
In the follow-up, Gold will continue to introduce more authoritative data from management departments such as traffic management and flood control, and continue to optimize this AI model.
“Traditionally, the map is for positioning, querying location and travel route, but we think this is not enough. Because in the real world, traffic jams, rain, business hours and other dynamic information are all for people’s travel. Great impact. Only with more connections and cooperation, LBS information can be more comprehensive, more stereoscopic, more dynamic, and better map the real world to the high German map, we can help users achieve better. Travel," said Chen Yonghai, vice president of Gao De Maps.
