You are not sizing your image. Try this:
;****************************************************
thisDevice = !D.Name
set_plot,'ps'
device, /color, bits=8
map_set,0,0,/iso,/ortho
tv, map_image(bindgen(16,16),/compress,/bil,xx,yy,xs,ys),$
xx,yy, XSIZE=xs, YSIZE=ys
map_horizon
device, /close
set_plot, thisDevice
;****************************************************
Cheers,
David
