Real-World Use Case of Large Area Coverage, High Resolution LiDAR for Network-Wide Utility Asset Management
Mapping of utility distribution infrastructure such as poles, pole assets, wires, transformers, and other fine features require extremely high-resolution data covering large geographic expanses. Until recently, these types of projects were cost prohibitive for distribution infrastructure where it was impossible to fly cost effectively the distribution right of way at the low altitude necessary to achieve point densities. Today?s new LiDAR technologies offer dramatic improvement in collection efficiency and cost for high resolution wide area coverage. Utilities can now take advantage of the economy of scale provided to update their entire GIS systems One of the largest utilities in the U.S. has performed a network-wide Geiger Mode LiDAR collection at 30 points/meter covering 54,600 square miles for subsequent mapping of over 13.6 million features (poles, streetlights, conductors, etc.). This project is one of the largest LiDAR utility projects to date at this scale and resolution. Presentation will discuss collection planning and execution, scalable distributed processing methods necessary to meet aggressive schedules for large data volumes, derivative products, automated conflation, and GIS integration.
