For the best coverage rate during flights at a certain altitude you must
allow for a time lapse between shots. The RGB sensor can take shots with
a minimum delay of 1 second between each photo. Multispectral sensors
can take shots with a minimum delay of 0.5 seconds between each photo.
To find out the minimum time to be respected depending on the flight
height refer to the following chart and diagram.
