We had major flooding in PA yesterday, as has much of the East Coast.
In this picture:

I want to mark some points on photos like the one above, draw some
outlines of flood limits, and then reproject the graphics onto maps. I
know the math exists, I just don't know how hard it is.

County officials are trying hard to understand the limits of
yesterday's event, to improve flood mitigation plans. I'm just looking
for ideas.

Geoffrey
