I started on creating photoscenery in Sbuilder. I am running in to troubles with the calibration. I got the Lat/Lon of each corner of the bitmap, so I can accurately place it in Sbuilder. When I try to calibrate the map by entering the Lat/Lon of 2 corners (I manually clicked where both of those corners were, as Pixel X/Y) I get this error: What is wrong with it? All of the Lat/Lon information looked exactly the same as the default coordinates so I thought it was compatible. Also, does anyone have some tips for getting the coordinates of the corners? It is VERY tedious to do that, took me a half hour lol.
