Extremely low level mapping

Here's a challenge :  I need to make a very low level "map" at about 3 or 4 Meters altitude (yep three !)   which can be studied in detail back at the university; with enough detail  to laboriously  identify, count and locate molluscs (muscles, clams and sea snails etc).  The reason this cannot be done in person is that it is a large area that is only rarely and briefly revealed on extremely low tides.  Am I on an impossible task here? ......  or can it be done ?

This has been done and it does work. The GSD comes out to be 1 mm or so. Start with small ares and go from there.

Map Pilot only supports flight down to 10 meters though.

The only aircraft we recommend for cost effective mapping at this point are the P4 Advanced/Pro and the Mavic 2 Pro.
