Maps on this site will be 2000 pixels wide.
1) From reading the GURPS Traveller pdf I bought, I will likely just go with the standard Traveller mapping methods. GURPS Space doesn’t have Sector and sub-sector maps. The info I found, and asking on the Steve Jackson Games forums, is there isn’t a sector map method. A Caretesian mapping method is used instead.
Since I am used to the CT Traveller methods elsewhere I will continue using that.
2) Navigation menus will be added at a later date.
3) There will be 9 sectors per area. More will be added later. Two Galaxy arms and a path connecting them.
