Oh, right! I forgot about all of the LIDAR-equipped planes in maritime communities! Those are way more economical to fly than any sUAS. /s in case that wasn't obvious.

In case you, or anyone else, were vaguely interested in learning:

-kelp extent mapping needs to be done in repeatable fashion, specifically at low tide; we can put up an sUAS any time

-the communities most in need of monitoring absolutely cannot afford to send planes up monthly

-many of the kelp beds in the PacNW are in restricted airspace; it is much easier to get an FAA clearance to perform low-altitude surveys using sUAS

-that restricted airspace I mentioned? Some of these kelp beds are on approach paths for the airspace. Even if a plane were the preferred choice for surveying, the planes are unable to fly in the pattern we need

-(drifting a touch off your point of LIDAR-equipped planes) satellite imagery with the required resolution is prohibitively expensive

-most construction projects wouldn't use a plane for tasks such as volumetric or area analysis

Consumer drones are quickly becoming the preferred, economical means for kelp health analysis, especially for communities that can't afford planes or purchasing satellite imagery.
