Hi LinuxUser1234--

 

I don't know if your end image is a sphere or just a map projection like you show in your question.    As you know, the text is nothing but latitudes and Longitudes.   But your map/sphere is going to be displayed on a flat screen.  There are several good books on map projections and the math to convert positions onto these projections and then to a flat screen.  My favorite is  "An Album of Map Projections--U.S. Geological Survey Professional Paper 1453"   printed by the Government Printing Office in 1989.  

 

Unless you know the exact projection you are using for your bitmap's image, it is going to be hard to back out what set of equations to use.   Do you know who produced the bitmap?  Perhaps ask them what projection they used.   The National Weather Service uses fairly fixed projections.

 

Hope this helps and good luck.
