This is where you enter details about the resolution of the map bitmap image. The bitmap resolution is entered as horizontal and vertical dpi (dots per inch).
Normally, Condes will retrieve the dpi information directly from the map file, but in some cases this information is missing from the map file.
If there is no dpi information in the map file, Condes will assume 100 dpi for both dpi values. If the assumption fails, you will have to enter the values manually.
If the dpi values are not correct, the map will be shown at a wrong scale; co-ordinates will not be correct; and calculated course lengths will be incorrect.
