reality simulation tools for testing autonomous vehicles. Using the FBX (Filmbox) format made the process seamless. Testing the testing grounds The HD mapping technology allowed Sanborn to create data sets for multiple environments and lev- els of complexity in the autonomous driving tests, including freeway, complex urban, and complex parking. For some sections of the city, Sanborn’s geospatial developers loaded the 3D mesh into a web interface, so the automotive partners could see the quality of the 3D reality view. Sanborn also developed web-based analytics that the partners could use to review and discuss vector and point data superimposed on the 3D reality mesh. Within the 3D viewing interface, it was possible to pre- cisely measure distances, volumes, surface areas, and other parameters. These capabilities create an accurate virtual reality, showcasing the driverless car in various road conditions. Showcasing the complex HD Maps in a 3D ur- ban setting provided context for high-precision features such as road lanes and traffic signs and signals, as well as surrounding buildings. The project highlighted the level of road intelligence that could be achieved in a 3D reality model. As they explore the virtual landscape for autonomous driving tests, several automotive partners are using Sanborn’s 3D demonstrations internally, as well as in meetings with department of transportation regulatory personnel. By making a modest investment of time and resources, Sanborn showcased HD Maps for au- tonomous driving and received positive responses from the participating automakers. With a premier collection of oblique imagery, Sanborn is poised to expand its HD Maps offering for autonomous vehicles, which have a promising future. Among the much-touted benefits, self-driving cars promise less stress for drivers, more mobil- ity for non-drivers, and less congestion and fewer accidents on roadways. Given the opportunities, Sanborn’s proprietary technology could fuel a lucrative market.
