Hi Antoine,
I would start with a black and white colorbar to display a scale. For a north arrow in IDL I would use something like this:
p = convert_coord(-74.5, [40.2, 40.5], /TO_NORM)
Draw North arrow:
ARROW, p(0,0), p(1,0), p(0,1), p(1,1), /NORMAL
XYOUTS, -74.5, 40.1, 'North', ALIGNMENT=0.5
Hope this helps.

Cheers,
Puneeth
