No that was an auto correct that I didn't catch. It should indeed be Terran instead of Terrain. As for actually using the map it might be better if I explain a little more thoroughly.
There is a bit of a pulpish feel to the story in my head. Think "high" low technology. The map.isn't just for navigation. It can be used to pull up resource data, political affiliations and so on. Maybe better to say interactive hologram.

As for the dimness of the various lines and elipsi, that is purposeful right now. That will get brighter once I have everything else populated. My eyes are as old.as I am and work about as well sometimes. Haha.
