   Plotting Latitude and Longitude
  I would would like to plot a point on a map which I render to the screen.  I'm given a Lat/Lon value.  My plan is to store the current center of my map as a Lat/Lon value.  Then, I would like to find the distance and bearing between the center of the map and the plot point.  I can plot simply by using the center point as my 0,0 and scaling the range to the bounding box of my map.  I can't seem to find the formula for calculating the bearing of two points given the Lat/Lon.  I'm fine on the distance.  Perhaps, my approach is a little too heavy handed.  Is there a better way to do this?  Thanks.   
  You have to decide what projection you want to use to draw your map. If you have no idea where to start, I would suggest you look at the Wikipedia page on map projection.If you know which projection you want to use, tell us, so we can help out with the formulas.   ;  Cylindrical would be fine.   ;  "Cylindrical" is a class of projections, not a specific projection.
