I am trying to convert a PDF map into SVG to then send it out to the laser cutter. I have been using the Image Trace tool with the "technical drawing" presets (and a bit of tweaking), which give more or less the result I want. None the less, there is a lot of cleaning required after this step: there are lines overlapping each other, breaks in the lines, etc. (see pictures below) So I was wondering if there is another tool, or set of procedures than can cleanly convert a PDF or JPEG or other pixel based map into SVG.
The goal is to then automate these steps so that virtually any map can be processed.
Here are pictures of 1) the original file, 2) how it looks after Image Trace, 3) how it looks after manually cleaning it, and how it should be more or less for laser cutting:
EDIT: I think the key in this project is really to have good files to start with. The US Census site has a bunch of maps (including Congressional District) in various formats. Mike Bostock provides a very useful tutorial for converting shapefiles (.shp) to SVG, and even more. Just Google "Command-Line Cartography".
