There is an amazing Traveller Map API available out there. Specifically, there’s a service that will produce a PDF based on your UWP list. But you know how it is. I bet half the Traveller referees are trying to code up subsector generators and mappers. Me too!
Here’s my SVG Mapper for Traveller. It comes with example data so you can figure out what format it expects by looking at it. Just click the Submit button! Remember, you need a browser that knows how to deal with SVG files – Firefox will do.
