I love these long-form build logs.

I just started reading, and I am making the faux-pas of commenting before finishing.

But, I'm wondering what the challenges are of automating the ROV to map a body of water's floor in a pattern. like a grid pattern, or whatever is most efficient.

At first I was thinking currents would cause displacement. but can't we sense the current moving us in undesirable ways and correct with thrusters?

And then I thought.. do lakes have currents? Do they have tides? can a ROV sense the boundary of a lake?

just further down the rabbit hole, realizing how little I've learned about the natural environment!
