Abstract
Utility Corridor Mapping Using LIDAR and Imagery for a GIS
Track: Pipeline Transmission
Author(s): Mike Renslow, Jim Gibson
Increasing delivery capacity of existing natural gas pipelines is key to solving the energy shortage in the western United States. This project required detailed digital elevation models and two-foot resolution, color digital orthophotos for a 612-mile corridor to be delivered in 10 weeks to support a complex ArcGIS-based application. This paper describes an innovative approach using LIDAR (Light Detection and Ranging) and aerial photography collected with airborne GPS and inertial data. By greatly minimizing ground survey requirements and traditional mapping procedures, all of the required data was delivered on schedule. The mapping will be validated with samples from GIS.
