Today I am adding Pappy's Pub by @Shessar:

Great work. Added it to the tutorial list.

This time it is @arsenico13's entry going into the atlas:

Lines can unfortunately just have a single path, they can't branch, so an additional section like that cannot be part of the line. What I would probably to in this case is to draw the outer line as a single line, and then have that "inner" vertical line as a separate line, and make sure to arrange the lines so it is below, not above the outer lines. This will give you much better corners.

Otherwise, it would have to be made as a polygon, which is doable, but a bit more work.

The sector import is mainly designed to work with official Traveller data, it was kind of assumed that people making custom stuff would draw the map themselves when this was made.

However, it is possible to point it at your own webserver instead of travellermap.com, and thus import the that way. Just make sure the webserver returns data exactly as the travellermap would do.

You'll find the configuration files in @System\Traveller\. Just make a copy of the example.cfg file there and edit it in a text editor, the data sources are at the top of the file. (Or use the more updated config file Ralf posted here.)

Note that I have never done this myself, so I don't have much additional data. I am not a Traveller player myself. But I know others have done this in the past.
