The high-precision dynamic map basic platform of the company's shareholding company, Guoqi Zhitu, has achieved daily updates of static data of high-precision maps in the Beijing demonstration area, and minute-by-minute release of lane-level traffic dynamic event information data. Can this map freshness meet the minimum freshness requirements of the upcoming L3 autonomous driving? In addition, when is it expected that the high-precision maps of the 120 cities that have passed the company's review will reach this freshness?

NavInfo: Hello, the company has been continuously investing in the research and development of crowd-source update technology and integrating it into the map production line. Currently, the map data update technology based on visual image sources has been applied to nationwide map updates. The proportion of self-collection has been greatly reduced, and it can achieve daily/hourly data element updates and releases to ensure the freshness and timeliness of the map. At the same time, crowd-source update technology based on semantic sources is being launched one after another, which can support high-frequency updates of high-precision and multi-dimensional road/lane/facility geometric attributes. Thank you.
