The Brandywine Airport contacted Howell Kline Surveying to get an up-to-date impervious coverage plan. In order to provide them with this plan, FAA Part 107 Pilots Paul Yost and Joe Keehn had to do some preliminary planning to get the job done.
Typically flight planning is simple. Most areas are not restricted for commercial drone flights, but this flight was over an airport, so a special FAA waiver was requested and approved before scheduling the flight with the airport.

The Day of the Drone Flight.
Pre-flight setup includes setting ground control points which improve the overall accuracy of the final orthographic image.
Drone Pilot Joe Keehn is shown placing the ground control at different locations around the airport.
Drone Pilot Paul Yost is shown setting up the GPS station on the ground control points so that the points can be synchronized with the orthomosaic image during processing.
Once ground control points are set and GPS is set up, it’s time for the flight to begin.
Since the flight covered such a large area, a visual observer was also required. Paul Yost of Howell Kline Surveying took that position at the other end of the runway. Paul (visual observer) and Joe (the Pilot in Command) remained in constant communication throughout the entire flight.
Paul Yost of Howell Kline Surveying kept a sharp eye out for the drone during the flight.
Once the flight was complete, the images were processed back at the office to produce a high-quality orthographic image that can be used for impervious coverage calculations.
Paul manages drone flights for Howell Kline using the Yellowscan LiDAR and the DJI Matrice 300 RTK Commercial Drone System. Howell Kline Surveying produces high-quality, accurate surfaces for surveying and engineering. Joe manages D.L. Howell and Associates drone flights using the DJI Zenmuse P1 Camera and the DJI Matrice 300 RTK Commercial Drone System.
