Park Grass (Sod/Turf) Fields
This survey was of a suburban park composed of large grass (sod/turf) areas of varying health. The DJI Mavic 3E Enterprise drone carried the Survey3N RGN and Survey3N OCN cameras using our DJI Mavic 3 MAPIR Survey3 - Dual 2 Camera Mount, along with the DAQ-A-SD light sensor (spectrometer) and covered the 35 acre park in one battery. Photos of our Diffuse Reflectance Standard Calibration Target Package (T3-R125) were captured just before the flight. The light sensor was started along with the cameras and logged any light changes. The RAW+JPG Survey3 images and DAQ log were converted and calibrated in our MAPIR Camera Control (MCC, desktop software), and the orthomosaic was produced in Pix4Dmapper.
