Thanks david, I'll have a look at that, although my problem is not the
poor resulution but matching it to the window ie

window,1,xsize=14*50,ysize=20*50
MAP_SET, /cylindrical, 0, 0, 0, noborder=1,/ISOTROPIC, $
/HORIZON, /GRID, COLOR=black ,limit=[44,-10,64,4]
MAP_CONTINENTS

gives the map and the long and lat lines, but they don't go to the
edge of the window. i want to bytscl an array which is fltarr
(14*50,20*50) and plot the border over the top?
