Very small plot trials may require increased overlap, increased buffer, and/or decreased altitude to ensure a minimum of 6 flight passes over the trial.

Environmental Conditions

Lighting
Imagery should be captured between the time of 2 hours after sunrise and 2 hours before sunset. Consistent lighting conditions required for best results, including avoidance of hard shadows cast over the field which cause bright spots and dark spots in the dataset.
Wind
Wind conditions should be within the specified limits of the aircraft or system being used to carry the imaging sensor.
Precipitation
There should be no active precipitation during imagery capture.
