This project was flown between March 7th,2020 and May 20th,2020 using Vexcel cameras. The project was planned at a photo scale of 1:15,880 for the Vexcel UCX cameras resulting in a mean pixel size of 11.4cm and photo scale of 1:18,900 for the UCX_Prime camera resulting in a mean pixel size of 11.3cm. All flights support a 45.0cm pixel size at 90% confidence interval. All photo acquisition flights were flown with a minimum sun angle of 30 degrees. All images were flown at a minimal 60% forward gain and 20% sidelap. Airborne GPS and IMU measurements were recorded at each exposed photo center. Post-flight airborne GPS was processed to survey grade accuracies for use in the project’s aerial triangulation process. All images were captured by Airborne Sensing Corp. (ASC) of Toronto Ontario and PHB Geomatics of Boisbriand of Quebec, using three Vexcel UltraCamX and one UCX_Prime digital cameras with airborne GPS and inertial measuring unit. The digital photo data was processed into 8 and 16 bit, four band (RGBIr), pan sharpened, digital colour images. |
