I've never coded in perl, but this seems to work :
B.t.w. is there some way to do very large areas ? hunderds of
thousands of km^2 ?
print GNUPLOT "set terminal table
unset surface
set contour
-set cntrparam level incremental 0, $l, 1000
+set cntrparam level incremental 0, $l, 5000
#set table 'tmp.cnt'
set output 'tmp.cnt'
#set terminal table 'tmp.cnt'
