As traditional infrastructure design methods migrate from 2D to 3D modeling, LiDAR data acquisition continues to present an opportunity to improve the base modeling process. This presentation will show how TopoDOT can be used to extract DGN vector data from point clouds to improve the quality of digital as-built base models which enable better transportation 3D design processes like Bentley’s ORD.

The United States’ National Geodetic Survey (NGS) plans to modernize their National Spatial Reference System (NSRS) in 2025, including adopting a new dynamic geometric reference (the North American Terrestrial Reference Frame of 2022 (NATRF2022)) and a new geoid-based height system (the North American-Pacific Geopotential Datum of 2022 (NAPGD2022)). To ensure continued geospatial referencing compatibility, the Canadian Geodetic Survey (CGS) plans to modernize the Canadian Spatial Reference Sy...
