If you are not able to fly that type of drones (DJI) due to DOD concerns - what other options do you have (outside of using drones from the local military). The map appeared to show that my area in Pensacola would be very restricted in the event a drone monitoring program was initiated.

Dr. Jarvis - when you ground truth, are you using BB scores for abundance?
- Juliet Christian
We do use BB scores

Dr. Jarvis: I believe you cited a flight altitude of 150 m. At that altitude, what is the approximate width of the field of view of the camera? Do you ever have trouble with image stitching closer to the deep edge of beds in areas of very shallow bathymetric slope (i.e. farthest from GCPs)?

At 115m FOV is ~40-50m. There are issues stitching large areas of deep water at the meadow edge (e.g. ICW). To get around this we have to fly a larger area (much larger than the SAV site we are interested in) to try to get some type of structure in the image (e.g. marsh, reef, sandbar). Another possible work around is using a more aggressive interpolation method in the stitching process. The GCPs aren’t used in stitching, they are only used for georeferencing the image.
