I've put together some star maps in text format at present. you can find them at
www.soltakss.com/starmap.zip.
There are 10 Text files - starmap01.txt to starmap10.txt.
Each file has a number of grids, each of which is a Z-Co-ordinate Plane. Empty space is marked by a dot (.) to help with navigation and stars are marked as letters. Navigation is by moving along adjacent dots.
What I have done is taken some files from
Halo Stellar Cartography and converted them into a grid format. I turned each co-ordinate into an Integer then divided them by a factor and saved the stars off in grids.
I'm not sure how useful they are because they are either very sparse or very clumped together. Maybe I need more stars to work with.
I haven't included the maps between each plane as they are all blank with no stars at all. They are handy for navigation, though.
If anyone else has any index of stars then I can do much the same with them to add more stars. All I need is an Excel or CSV file containing the Star Name and Relative X,Y and Z co-ordinates.
If anyone has any comments or ideas of how to improve the maps then let me know.
