This is where you enter details about the dimensions of the map image. The map size is entered as width and height in millimetres.
Normally, Condes will retrieve the dimensions directly from the map file, but occasionally this information is missing from the map file.
If there is no dimensions information in the map file, you will have to enter the values manually.
If the dimension 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.
