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 retrieves the resolution information directly from the map file, but in some cases this information is missing from the map file. 

If there is no resolution information in the map file, Condes will assume 100 DPI for both resolution values.  To override this, you can enter the values manually.

If the resolution values are not correct, the map size is incorrect and co-ordinates are not correct - the map is then printed at a wrong scale, and calculated course lengths are incorrect.
