Need a cleaner Result from Lake Map

[briandobo (Brian)]

I took the file “2nd Crow Wing.png” and converted it to an SVG using Inkscape. Then imported to Carbide Create.
I created a vcarve toolpath with the 3000+ vectors. It looks very sloppy to me. It looks like the vectors a duplicated.
I have attached the c2d file as well as the original file.

How can I get this to be cleaner? Is this something that needs to be done in Inkscape or CC? How do I accomplish a nicer, cleaner result?
Here is a snippet of the SVG in CC.

In Inkscape when you trace a bit map there are controls to increase/decrease the sensitivity. I have the current version and sometimes the preview does not work very well. So try increasing and/or decreasing the sensitivity of the trace.

The picture is not the best but I changed the threshold from low, med and high and you can see the differences.

So try changing the threshold and in the end you may still need to go in with the zoom in design with CC and just clean up what you dont want.

Is it not possible to get the vector source?

If you’re going to engrave this using V-Carve, get rid of all the garbage (small circles, ovals, stuff in the middle of the depth lines). This gets it down to about 56 vectors. And it carves a lot nicer.

What I think I would do is replace each of the double line vectors with a single vector, each on a different layer, and pocket each layer down to the next depth line.
