The Shatian and Four Level models use adapted OpenStreetMap road data. The Shatian standard-arc model is schematic; the half-turbine model references a road layout and turning relationships with newly constructed circular-arc geometry. These fitted, simplified models are not live maps or engineering surveys.
U.S. Geological Survey
The Four Level model uses elevation information from the U.S. Geological Survey 3D Elevation Program, project USGS_LPC_CA_LosAngeles_2016_LAS_2018. Coordinates and elevation profiles have been fitted, simplified and adjusted for visualization. This is not an original USGS point-cloud product or an endorsement by USGS.
