HIGH DEFINITION (HD) MAPS
FOR AUTONOMOUS VEHICLES

Home > What We Do > Mapping > HD Driving Maps for Autonomous Vehicles

Self-driving cars are no longer a futuristic idea. Major auto manufacturers have already released, or are soon to release, self-driving features that give the car some ability to drive itself. To operate safely, autonomous vehicles will require purpose-built HD Map datasets, which contain significantly more detailed information and true-ground-absolute accuracy than those found in current conventional resources.

Sanborn’s Advanced Technology group has developed proprietary HD Mapping technology that leverages Aerial Imagery, Aerial LiDAR data, and Mobile (driven) LiDAR data to create standardized, high-precision 3D base-maps focusing specifically on self-driving vehicle models and markets.

Sanborn HD Maps For Autonomous Driving Feature:

  • Accuracy in the 7-10cm absolute ranges.
  • Highly detailed inventories of all stationary physical assets related to roadways such as road lanes, road edges, shoulders, dividers, traffic signals, signage, paint markings, poles, and all other critical data needed for the safe navigation of roadways and intersections by autonomous vehicles.
  • Electronic Horizon Predictive Awareness – autonomous vehicles will know what lies ahead.
  • NDS format compatibility (NAVHD).
  • ADASIS v3 standardization.
    • Proprietary Geo-Database schematics that have been reviewed by top-level DOT industry consultants.
    • Integration compatibility with all forms of Municipal Data, Vehicle Supplied Data, and Crowd-Sourced datasets.
    • Conflation functionality designed to improve the absolute accuracy of 3rd party Road Data (probe or alternative source) to high-precision standards.
    • Online web-based analytics – designed for auto teams to review / discuss vector and point data super-imposed digitally on top of high-resolution imagery.
    • Lightweight data size – data is optimized and compressed for onboard CPU systems.

Sanborn HD Maps – Complex Urban Datasets

Sanborn collected aerial and street-level data for the Silicon Valley area (Santa Clara) in 2016, 2017, and 2018, and has constructed sizable target areas in Sunnyvale (Heritage District), Palo Alto, 101 corridors, and surrounding locations. Sanborn teams are refreshing and expanding the 2017 HD Maps with new 2018 data – showcasing Sanborn advanced change detection algorithms and road network feature update programs. Sanborn HD Maps for Autonomous Driving data is currently available for California, Arizona, and Michigan.

HD Map – Precision 3D Road Network Data Features:

HD Maps for Driving

      • All road network features are available as precision 3D global data files (GeoJSON, ShapeFiles, and CSV in WGS-84 Ellipsoidal projection).
      • All road network features are attributed and classified for the most sophisticated autonomous driving programs.
      • Datasets are available for all environments and levels of autonomous drive testing complexity – Freeway, Complex Urban, Complex Parking, etc.
      • Complex Urban HD Map datasets deliver high-precision road feature intelligence:
        A. Painted Lines – Painted lines assembled as precision 3D map features, polygons, and lines.
        B. Signs – Signs represented as locational precision XYZ features designed to guide the most advanced target recognition for high precision optical localization.
        C. 3D Building Models – Buildings constructed and attributed with height points for advanced 3D City Model visualization.
        D. Signals and Stop Lines – Traffic signals and stop lines collected in absolute 3D XYZ space delivering precise locations for intersection control protocols.
        E. Semantic Data – Lanes, Junctions, Road Segments, DRIVELINES, are assembled with the industry’s most robust attribution tables.
