PDF’s I found on the State of Michigan website but that obviously isn’t a cut file

… it might be closer than you think. Many PDFs contain vector information, the trick is getting at it. Do you have a link to the specific bathymetric topo map you’re talking about?

Here’s an old thread (December 2017!) about the process and how it can be frustrating:

Is PDF layer extraction without acrobat possible?

You would think that, but it’s definitely not in Inkscape’s wheelhouse. I’ve done it once with acrobat on a friend’s computer who had the full license, and it was trivial. @forhorsman – As for the source pdf, any quadrangle from nationalmap.gov is like this. Here’s just one, of my hometown growing up: (603 Glowforgers, represent!)

PS also, welcome to the forum! We love new faces around here.
