# Purpose:	Illustrates interpolation methods using same data as Example 12.
# GMT progs:	gmtset, grdview, grdfilter, pscontour, psscale, pstext, surface, triangulate
# Unix progs:	$AWK, echo, rm
#
# First make a cpt file as in example 12:
#
#z0=`minmax table_5.11 -C -I25 | $AWK '{print $5}'`
#z1=`minmax table_5.11 -C -I25 | $AWK '{print $6}'`
#makecpt -Crainbow -T$z0/$z1/25 > ex16.cpt
#Hand edit to add patterns and skips
#
# Now illustrate various means of contouring, using triangulate and surface.
#
