Need some help capturing line drawing from graph paper

[Ascension]

Sure there all sorts of fancy things to do...knobs to push, dials to turn, but why? If you had the cyan grid it could have taken about 10 seconds...select by color, new layer, fill with white. I did try to blur the whole thing by .5 then max out the contrast and brightness and that was fairly decent but required going back and hand-painting white over a large amounts of dots...would have taken 5 minutes. So, I just traced it by hand in Ps, 5 minutes.

If I had CorelDraw, I could do this. Unfortunately, I only have GIMP to work with for now. There has to be a trace function using GIMP, separating the traced layer from the original. I haven't been able to figure it out, and the GIMP user manual isn't much use. Grrrr ..... I was hoping to avoid investing in software .....

What you need is to create a new layer, trace by hand over the original on the new layer, maybe in red or something like that to distinguish the two, and then delete the old layer. The exact details about which menus and buttons to push for creating or selecting which layer your on I will leave to the Gimpers. I think Devin probably has the easiest solution given the type of map your trying to extract - unless this is a pretty simple part of a very extensive or complex set of them.
