What is the coordinate system that DCS maps use to convert from (x,y) to (lat,lon) ?

[_Defi]

I want to know what coordinate system that DCS uses to convert from X,Y locations on the map to Lat,Lon on the geographical maps.

Does it use a specific model for the ellipsoid of the earths surface, a flat earth, or some other kind of approximation?

I have found out that it uses the method of TRANSVERSE MERCATOR to map (x,y) -> (Lat, Lon). 
Here is the input for the Persian Gulf

 

    PersianGulf: {

        central_meridian: 57,

        false_easting: 75755.99999999645,

        false_northing: -2894933.0000000377,

        scale_factor: 0.9996,

    },

Hey Defi,

Where did you source the following information?  I am trying to find it for other maps for a project I'm working on.  Thanks.
