Dyess AFB Survey Grade Mobile Lidar and SUE Survey

Dyess Air Force Base, located west of Abilene, Texas is expanding. Home to B1B Stealth Bombers and a C130Air Mobility Unit, Dyess Air Force Base is an important asset within the Air Force.

The base is expanding their runway and taxiway to support increased aviation activity. To support the expansion effort, Continental Mapping was retained to complete this technically advanced and comprehensive survey.

The project area consisted of a 10,000-foot taxiway, apron, and infield area within the base. Key objectives included the acquisition of a high-accuracy topographic survey, field locating all above ground assets as well as underground utilities, surveying all concrete joints and controlling all data collection to ensure a tight accuracy. Mobile lidar was utilized to efficiently and accurately gather an extremely dense point cloud of the terrain. The data was acquired in a single afternoon. Due to national security reasons, ground-based imagery that helps match up the point cloud to existing features was not usable. In order to overcome this obstacle, Continental Mapping drove the project area at a very slow pace. This worked well as Continental Mapping was able to extract high accuracy surface features, assets, and topography despite having no imagery to support the extraction.

Continental Mapping also utilized a vacuum truck to locate sub-surface utilities. Conventional survey techniques were used to set permanent monuments, confirm as-builts, provide control for the mobile lidar acquisition and shoot other above ground assets of interest.
