Convert Lat/Longs to X/Y Co-ordinates http://stackoverflow.com/questions/4953150/convert-lat-longs-to-x-y-co-ordinates to do this . Any code would be much appreciated. c maps coordinates coordinate systems share improve this question You need.. The easiest approach is to figure out exactly what lat lon coordinates correspond to the 0 0 pixel and the 1017 915 pixel. Then you.. minLat works out how far you are between the two reference coordinates and gives 0 to indicate that you are at the first one 1 to indicate..
