Current Challenges and Forecast trends in respect of Mapping for Autonomous Vehicles
Automakers around the world are planning to launch semi-autonomous vehicles by 2020 and have fully autonomous vehicles on the road by 2030. It is estimated that by 2035, in China alone, there will be approximately 8.6 million autonomous vehicles on road, which will be broken down into 3.4 million fully autonomous vehicles and 5.2 million semi-autonomous vehicles.
A crucial piece of technology in driverless cars is high-definition maps or HD maps. The digital maps used in navigation devices and mobile phones today are relatively simple as they are primarily created for humans who are able to understand and follow simple instructions (left, right, straight ahead) as they navigate. However, autonomous vehicles, machines and robots require a much different type of map purposely built for robotic systems before they can take control of the steering wheel (well actually there will not be a steering wheel).
The robotic system needs much more and much more precise data.
However, creating HD maps is not only a technological challenge. A far greater challenge (especially for international companies wishing to access China’s auto market) will be government regulation.
Accordingly a myriad of legal challenges face market players including international companies when developing HD maps for autonomous vehicles in China.
What is a High Definition Map?
HD maps usually refer to maps particularly created for self-driving purposes. In order to allow semi-autonomous and fully autonomous vehicles (levels 3, 4 and 5) to safely operate on the road the vehicles must have built in technological capabilities to guide, brake, change lanes, use built-in cameras and sensors to avoid collisions and rely on artificial intelligence to analyze and adapt to new circumstances as they are shown in real-time HD maps.
The HD maps are not a static map of the past but are essential for fully autonomous vehicles which rely upon them to make real-time decisions. For this reason HD maps require far greater precision to centimeter-level accuracy unlike traditional GPS maps which are only accurate within five to ten meters. Such HD maps can even track weather through sensors on windscreen wipers and elsewhere. In addition to being an accurate snapshot of the geographic location the HD maps will also need to interact with billions of 3D points collected by LIDAR technology (i.e. laser based radar). This data allows the system to replicate the road surface and also capture details such as slope and curvature of the road. This will allow autonomous vehicles to understand and respond to real-time events such as traffic, construction work, accidents, lane closures, weather and other events that can impact the journey.
Naturally the amount of data required to create HD maps is massive. Automakers and mapmakers are using multiple cars to drive on the same road and aggregating the obtained data. For this reason data mass will be crucial. The more cars on the road, the more data is collected and the higher the quality of the HD maps.
General Legal Challenges in Creating HD Maps
Similar to other maps, regardless of form or nature, HD maps are strictly regulated by the laws of the relevant jurisdiction being mapped. This is particularly so in China where mapping activities are strictly regulated due to issues of national security, concerns over demarcation of borders, state secrets and privacy.
China has for this reason traditionally regulated the collection, preservation, ownership, usage and export of geospatial data very tightly.
Compounding the legal complexity in respect of HD maps is the gap between technological development and lagging regulation and policies.
China has also been taking steps to improve privacy protection for its citizens. In this regard China may follow in part the example of the European Union which has taken a very restrictive position on data collection and analysis. The European Union’s rules limit the ability of companies such as Google from collecting data in respect of road conditions and mapping street views. This is due to concerns that personal information in unencrypted wi-fi networks will be swept up as part of an overall data collection. The European Union has fined Google on several occasions, demanded copies of its data and placed limits on the material collected. China has a complex relationship with Google. In 2010 after Google refused to comply with Chinese censorship policies the China National Administration of Surveying, Mapping, and Geo-Information (NASG) denied Google’s application to provide online mapping services. Accordingly Google will need to find a solution for its relationship with China or be potentially excluded from the world’s largest automotive market.
It will be difficult to balance protection of privacy and national security on the one hand and the desire to stimulate autonomous technology on the other hand. Different stakeholders will have very different interests and it may take time before the dust settles.
Overview of the Regulatory Framework in China
The activities for creating HD maps by using high-resolution LIDAR to detect the location of the surroundings and cameras to constantly scan streets, buildings and other objects that can be “seen” or “perceived” by the sensors or to record GPS coordinates clearly fall within the ambit of China’s regulations on surveying and mapping.
There are a number of legal hurdles to overcome in order to develop HD maps under the current China legal regime:
License is a Must
The current PRC Surveying and Mapping Law requires surveying and mapping in China be carried out exclusively by entities holding a license issued by the relevant governmental authority. In respect of electronic navigation maps, a license is required to be issued by NASG (“ENM License”).
In 2016, NASG issued an official notice (“2016 NASG Notice”) which specifies that the autonomous map is a new type of electronic navigation map and data collection, editing, processing and production of autonomous driving maps can only be handled by an entity holding an ENM License. The 2016 NASG Notice further specifies that when an ENM License holder cooperates with automakers in developing and testing maps for autonomous driving, the ENM License holder must separately conduct the surveying and mapping.
In the market the ENM License has the reputation as being a “gold key” for mapmakers in China due to the difficulty in obtaining one. At present, 22 Chinese entities have been granted the ENM Licenses. NavInfo, in which Tencent is the second largest shareholder, is the first to have obtained the ENM License back in 2001 and Jingdong, China’s second largest online retail platform, is the 22nd entity to obtain an ENM License which was issued in early 2020.
This license regime means currently in China only these 22 entities are permitted to produce autonomous driving maps (i.e. HD maps). The Chinese government is relaxing the requirements in respect of the issuance of such licenses as in recent two years, the authority issued around 9 ENM licenses while in the previous 16 years, the authority only issued 13 ENM Licenses.
Security and Secrecy requirements
China has very strict secrecy requirements in respect of sensitive geographic information. Key requirements under China’s current regulatory regime are as follows:
1) Public maps cannot be accurate beyond 50 meters. This requirement makes it difficult to develop the accuracy required for HD maps which require extreme precision (i.e. at the centimeter-level). Autonomous vehicles will not be able to operate safely with such lack of precision. In the market, there are suppliers already able to graph roads down to within several centimeters in accuracy.
2) Public maps cannot present the attributes of the height, width or weight limits or slope of key bridges or the attributes of height and width of key tunnels. In addition, the maximum longitudinal gradient and minimum curvature of express ways, elevated roads, ramp ways, streets and internal roads are not permitted to be made public. These restrictions will make it impossible to compile sufficient information required for HD maps.
3) Navigation products including electronic navigation maps, navigational software and devices shall not have, by text or database, any function-option that displays, records or stores any basic geographic data involving state secrets (e.g. coordinates or elevation). Again this data is key for HD maps and therefore these prohibitions present a major challenge to creating HD maps in China.
4) Technical spatial processing must be carried out for electronic navigational maps prior to publication, sales, distribution and usage. Data of an electronic navigation map that has not been gone through the said technical process will be treated as state secrets at the “confidential” level. Under PRC state secrets law, there are three levels of State secrets – top secret, confidential and secret – a failure to observe the confidentiality requirements in respect of a state secret can lead to severe administrative penalties and even criminal liability.
5) State secret cases are serious matters. The Yunan provincial geographic bureau investigated Coca-Cola for having illegally surveyed part of the province by using handheld GPS equipment on its trucks. Coca-Cola maintained that the tracking was only done for logistics purposes. In 2010 the Beijing No. 1 Intermediate People's Court sentenced Dr. Xue Feng, a naturalized American citizen to eight years prison for purchasing commercial information on oil wells in China which was considered to be a state secret. 
6) Map approval process. Under China’s current regulatory system electronic navigation maps must be examined and approved by NASG or the local authority at provincial level before publication or display. This also extends to any update on the content presented within such maps or any change as to the data range or any conversion of data type. In all these cases re-approval must be obtained from the authority.
This examination and approval process will be unworkable for HD maps as they will be updated in real time as large amounts of data collected by the sensors of the autonomous vehicles will be constantly uploaded.
Legal restrictions on foreign investment
Given the political sensitivities and the practical restrictions it is not surprising that surveying and mapping is a restricted area for foreign investment.
Currently, foreign investment in creating electronic navigation maps is prohibited. In addition, map data generated from autonomous driving technology testing or road testing (including adding more data, elements or accuracy to traditional electronic navigation maps) must be kept in accordance with secrecy requirements in relation to surveying and mapping and shall not be provided or shared with foreign entities, individuals or foreign invested entities (including wholly foreign owned entities or joint ventures).
Further the PRC Surveying and Mapping Law which was also revised in 2017 states that foreign entities or individuals involved in surveying or mapping must cooperate with China departments or entities to ensure no involvement of state secrets or issues in respect of Chinese national security.
For foreign investment in internet mapping services, while it is not prohibited under the 2019 Special Administrative Measures (Negative List) for Market Entry Foreign Investment (“2019 Negative List”) or a Sino-foreign joint venture is required under the same negative list, given a value added telecom license may be required for providing the internet mapping services in China, it is anticipated that the foreign investor shareholding in such joint venture cannot exceed 50% Currently hundreds of Chinese entities have obtained the Internet mapping services with class A or B license issued by NASG or the local authority at the provincial level.
The holder of class A license for Internet mapping services is entitled to provide a full scope of services including (i) map search, location services, (ii) geographic information mark services, (iii) map downloading and reproduction services, and (iv) map sending and reference services. A holder of class B license is not entitled to provide services outlined in (iii) and (iv) above.
Only few Sino-foreign joint ventures have obtained Internet mapping licenses including Microsoft (which it inherited from Nokia) and General Motors (Shanghai OnStar).
Market Practice in China
As surveying and mapping is highly regulated under the current China legal regime international companies will need to carefully review their plans to ensure compliance with local regulations.
A number of international automakers and mapping firms are in practice adopting an “OEM model” or forming partnerships with Chinese mapping firms in order to tap into the China market.
Option 1: OEM Model
Traditionally, navigation systems installed in new vehicles are ordered from map provider by OEMs. In such case the base map data is normally procured by the OEMs directly from the map data supplier (“First OEM model”) or the map provider processes the base map data and supplies custom-made vehicle specific “mapping data and navigation application” which can be installed on new vehicles (“Second OEM model”).
Under the First OEM model, the map supplier normally provides the OEMs with its base map data information (such as road surface information, and POI data etc.), for the OEMs to process and develop their own unique in-vehicle navigation system on top of the base map data information. Therefore, the ultimate user interface of the navigation system presented to the end user (driver) will be dedicated for the specific OEM, although both OEMs do procure their original base map data information from the same mapping firm.
For vehicle manufacturers which are concerned about brand image the First OEM model offers greater flexibility in designing a user interface and experience.
Under the Second OEM model, the map supplier provides the OEMs with a complete package of the custom-made navigation system rather than only being a supplier of the base map data. Under the Second OEM model mapping firms are involved in the design and creation of the in-vehicle navigation systems and contribute to the development of a user friendly interface.
Option 2: Partnership with Chinese Mapping Firms
In July 2017, TomTom and Baidu made a public announcement to form an alliance in the development of HD maps.  Pursuant to this Baidu will leverage TomTom’s HD map-making platform combined with its artificial intelligence capabilities to improve HD map-related technologies as they are utilized in China. The alliance brings TomTom a global mapping company together with Baidu a major mapping service provider in China.
Similarly, NavInfo and HERE have established a 50:50 Sino-foreign Joint Venture in May 2017. The main purpose of the joint venture is to provide HERE’s clients with a global location service platform with content and service based solutions that includes China mapping data and real-time information.
China does face a dilemma – on the one hand it has a strong interest in tightly regulating surveying and mapping activities but on the other hand it has a strong ambition to become a world leader in autonomous cars.
We expect that autonomous cars is so important that China will indeed make necessary change as to how it regulates surveying and mapping laws or at least their practical implementation in regards to HD maps.
One example of China’s efforts in this regard is the 2017 revision to the Surveying and Mapping Law which required a unified national system of continuously operating reference stations (CORS). The CORS system is able to provide accurate positioning to the centimeter or even millimeter level. In May 2017, the national CORS system was put into operation – this is a fundamental step in providing the accurate positioning data needed for HD Maps in China.
In addition, the 2016 NASG Notice also notes that the authority is speeding up the study and formation of policies on autonomous driving maps. In a news conference held by NASG in 2017 it was announced that the authority will strongly support the development of autonomous driving in China and has been actively conducting research on relevant policies and map processing technology.
In addition, the Ministry of Natural Resources (MNR), China’s current surveying and mapping authority, is revising the current Surveying and Mapping Qualification Regulations and the amended version may be issued in 2020, which may include updated requirements (may lower the threshold) on ENM License.
However, we are less optimistic about the restrictions on foreign investment being relaxed anytime soon. We would anticipate that these will remain in place so that foreign companies interested in the China market or needing to serve the China market as part of a global strategy will need to find an accommodation within the current framework – either a joint venture or cooperation.
