As the prime contractor, DJ&A was responsible for the delivery of an aerial LiDAR acquisition project for four sites near Fairbanks, Alaksa, covering an area of approximately 13 square miles. DJ&A provided all project survey control and worked with a subconsultant to gather all LiDAR data. DJ&A was responsible for coordination with the client and subconsultant for the early acquisition period, as the timing was a key element to the client in meeting their project needs.

Over 200 ground check points were surveyed and collected to be used in the LiDAR calibration process. An additional 120 random ground verification shots were obtained under various vegetation types to truth and ensure LiDAR data accuracies.

Deliverables included a classified LiDAR point cloud (LAS v1.4 format), 0.25 meter hydro-flattened DEM, normalized intensity imagery, water’s edge breaklines, and other supplementary data.

Key Services

  • Provided static and real-time kinematic global positioning system (RTK GPS dual frequency) aerial imaging control surveys
  • Ensured quality control
  • Delivered a classified LiDAR point cloud

Value Added

With up to eight survey crews ready to mobilize at any time, this project demonstrates DJ&A’s ability to mobilize survey personnel in a timely manner, even to remote sites as far as Alaska.
