Yu Zhijie, vice president of map technology in Goldtech, said, "We are taking a brand-new way to make maps. Hundreds of millions of high-tech users use maps and navigation services every day, so we can quickly know where the roads are blocked and where the shops are closed. These living data make the map development never stop, making the map different every second. "

It is understood that Gaode Map has been collecting map data independently since 2002. Since 2007, Gaode Map has been trying to make maps with "live data".

At that time, we used real-time traffic big data to provide real-time traffic services. Now, the ability of living data has penetrated into every link of the production and development of Gaode map.

On the map of Beijing urban area spread out on the big screen of Gaode Map Data Center, there are countless moving dots, all of which are GPS positioning returns when driving on the road.

These big data can first enable Gaode Map to capture traffic dynamics in real time, understand the smooth situation, driving speed, congestion reasons and traffic events such as accidents, control and construction in real time, and adjust or remind users of navigation routes according to traffic conditions.

According to reports, 78% of the accurate real-time traffic big data of Gaode Map comes from UGC crowdsourcing data, and 22% comes from floating cars in taxis, logistics vehicles and other industries. Among the real-time traffic dynamic event data of Gaode map, 85% comes from users' reports, and the rest comes from traffic control and the government.

In addition, Gaode Map also benefits from Alibaba's big data, such as rookie waybill data, logistics vehicle data, and word-of-mouth takeaway order data. Through data fusion, Gao De said that we can explore the addition and change of POI and strengthen the basic data of the map.
