A few days ago, NavInfo presided over the preparation of GB/T35645-2017 Framework Data Exchange Format for Navigation Electronic Map and GB/T35640-2017 Data Model and Exchange Format for Public Transportation Navigation and participated in the preparation of another eight national digital map standards, which were officially implemented on July 1.
The ten national standards, officially released on December 29, 2017, were jointly prepared by NavInfo, National Geomatics Center of China, Wuhan University and other enterprises, government agencies and universities.
"This series of standards plays a normative and guiding role in the exchange format and production of navigation geographic data, thus laying a good foundation for the smooth development of intelligent traffic, connected car, location-based services and other industries" Said Jin Shuixiang, SVP of NavInfo.
With the increasingly wide use of automobile navigation and the rapid development of the navigation application industry, the demands of the industry for navigation electronic map data standardization have also become increasingly more urgent.
In the implemented digital map-related national standards, NavInfo abstracts, sums up, classifies and stores geographic information related to navigation in the real world to relational database with experience in map navigation data coding, maintenance and processing. It also stipulates the principles of geometric storage, attribute coding and relationship maintenance of navigation elements, formulates the navigation electronic map framework data exchange format standard suitable for China's national conditions, and provides applicable solutions for data exchange specifications for the industry.
In the field of public traffic, the public traffic navigation data model, element and exchange format are stipulated. It provides support for the standardization of public traffic navigation services, reasonable arrangement of travel time and the reduction of travel costs to improve people's willingness to travel with modes of public transport.
In addition, another eight map standards prepared by NavInfo cover digital map updates, geographic information point of interest, mobile map data specifications, indoor location information, etc.
Relying on the development of digital maps and focusing on the top-level strategy of "Intelligent Automobile Brain", transformation of NavInfo to future intelligent driving has achieved initial success. The formulation of national standards related to digital maps is of great significance for the standardization and commercialization of intelligent location products, for example, autonomous driving maps.
Professor Li Bijun participating in the release of the standards from State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing of Wuhan University said that release of the standards was conducive to promote the sharing of electronic maps and improve the quality of services, and solve the problems, such as a large number of repeated investments arising from government departments and map manufacturers due to the respective closure of resources, which will generate remarkable social and economic benefits. At the same time, it's also of great guiding significance for the current and future production and commercial use of driverless and connected automobile electronic map products.
As the one presiding over and participating in the implementation of the national standards, NavInfo expects that the establishment of the standards can create greater value for the industry and cooperative partners and even provide help for the arrival of the era of autonomous driving.
