Surface, sub-surface mapping and geohazard identification and associated risk mitigation for power transmission

Capture and analysis of remote sensing data of surface and sub-surface conditions can provide significant logistical information for improved efficiencies and cost savings in transmission construction, upgrade, and maintenance programs. Cutting-edge LiDAR topographical mapping as well as sub-surface electro-magnetic and magnetic sensing datasets are practical tools for evaluation of surface and subsurface geologic-related hazards (`geohazards'), landslide and fault avoidance, alternate routing options, salinity/corrosion detection, determining construction feasibility and constraints including bedrock and overburden detection, encroachment discovery, and lightning strike mitigation. Resulting datasets can be placed into a GIS database as well as a three-dimensional visualization environment for complete design planning, asset management and future health modeling.
