Map Projection Help


Recommended Posts

Hi everyone

I'm putting off my Masters degree work by finally creating my own KSP flag. I've done this before but never really put any effort into designs. 

Anyway, I've hit a bit of a stumbling block - I want a specific map projection type of Kerbin, known as "Azimuth Equidistant". This is the type of projection used in the UN flag as well as the Kerbalised version already in game. Does anyone know how I might go about obtaining the data required to produce this map projection type for my own use (and how to then make it)? Or have the projection already (I googled it and found nothing)?

If I've not been clear about anything, please let me know.

Thanks!

Have you thought about feeding a more conventional map of Kerbin to GDAL (gdaltransform function to be specific) ?

Spoiler

Assuming my google-fu is still strong:

PROJCS["World_Azimuthal_Equidistant",
    GEOGCS["GCS_WGS_1984",
        DATUM["WGS_1984",
            SPHEROID["WGS_1984",6378137,298.257223563]],
        PRIMEM["Greenwich",0],
        UNIT["Degree",0.017453292519943295]],
    PROJECTION["Azimuthal_Equidistant"],
    PARAMETER["False_Easting",0],
    PARAMETER["False_Northing",0],
    PARAMETER["Central_Meridian",0],
    PARAMETER["Latitude_Of_Origin",0],
    UNIT["Meter",1],
    AUTHORITY["EPSG","54032"]]

BAM

Click for huge

For those curious, all I needed to do was download a map of Kerbin, flip it horizontally so it was backwards from what it really is (for reasons that are mathy and I don't understand), then Filters->Polar Coordinates in Gimp. Then some quick resizing etc.

It would probably look better rotated 90 degrees so KSC was directly south but you can do that part :D

Okay I lied I wanted to see it and it's much better in my eyes like this.

Again, click for larger version.

@MR L A if you want to do this yourself or for other bodies, a good tool to use is Cartographer by Sigma88.

https://github.com/Sigma88/Sigma-Cartographer/releases/tag/v0.3.0

A guide on how to use it can be found here

https://github.com/Sigma88/Sigma-Cartographer/issues/16 look here for some explanation of it.

I used G.Projector from NASA's download pages to get the projected map. Anyway, I had a little fun:
