I have received an unusual mapping request and am wondering is anyone here might have experience with a similar project.
The job is to map aggregate stockpiles for inventory estimates at an asphalt plant. The site is dead flat (other than stockpiles) but is located within controlled airspace with a max LAANC altitude of 50 ft. Yikes! I have not reconnoitered the site yet but am told that the stockpiles may approach that height. If so, then obviously, game over. However, if they are lower, say 30 feet, I wonder if any have had success attempting to map at this altitude/clearance and, if so, if they can provide any suggestions. GPC’s will be established prior to flight. Site is only about 4 acres so high overlap and slow speed is feasible.
If I have sufficient clearance for the flight I was thinking maybe a cross grid with overlap of 75%. If this makes sense at all, would gimbal be best at nadir or maybe an angle, say 65 degrees?
Any input appreciated.
