What if I don’t understand what I see? lol What if I don’t know what I’m doing and I’m all toes?
I drew 3 polys because the Ohio southern State boundary /northern WV and KY States’ borders follows the river. I tried to keep the river in the middle of the polys. My polys covered from Wheeling to Marietta Ohio; then Marietta to I think near Huntington WV, and Huntington to the western State border of Ohio which includes Cincinnati Ohio.
I highlighted all the map titles it showed for each poly (checked and unchecked). I sent those to my own email until I get direction from you about whether I did it right.
I don’t know how closely to draw a poly along a river but still show both river banks. I suspect you could cut away some on my polys.
As far as the river width: “The river’s valley is narrow, with an average width of less than 0.5 mile (0.8 km) between Pittsburgh and Wheeling (West Virginia), a little more than 1 mile (1.6 km) from Cincinnati (Ohio)…” If you do not have to cut out any of the river, we could tag boats / barges too, since The Ohio is // has always been one of the most used gateways to the west, for people and goods.
The biggest problem with polys is the zig-zagging river pathway. It’ll make for some strangely cut maps.
Please advise if I am on the right track and should fwd to you my map ID numbers? What address should I use?
Or if I need to start over; and if so, how to poly this long area correctly?
