For those of you you not photographing the sea, you can now set the ground elevation height. It's still just a flat approximation but it should give better results than pretending everything is at sea level. Will look into using DCS height maps in due course...
Also added cursor coordinates that can be copied with CTRL-C. Coordinates are really just to get ballpark locations. I wouldn't use them for pre-planned precision strikes.
Coord display also valid in the image preview if you want to look around your un-warped photo and pick a point on it, it should show the coordinate as if it has been mapped out onto the ground. Check the "Grid" preview to see visualise the warp that is being factored into the coordinate transformation.
