Transportation Infrastructure Digital Design Model (DDM) Utilizing Arc
Track: Highways and Roads
Authors: Kourosh Langari

UCalifornia Department of Transportation is exploring utilization of ArcGIS Pro environment to establish 3D Topological model and 3D spatial relationships by representing features as an underlying graph of topological primitives comprising nodes, faces, and edges (sometimes called Reality Capture). These primitives, together with their relationships will define design grade Digital Terrain Model (DTM). The DTM models are part of the larger cadastral fabric to represent California earth.
