Hi,
I've got a bunch of data in arrays that correspond to lats, lons, and
elevations at points on a map. I'd like to create an elevation map
with this data. The problem is that not every point on the map has
data associated with it (the array entries are linear tracks across
the map - data taken by satellite fly-overs). I've been successful in
plotting these position data points.
Something as simple as plotting points whose color correspond to an
elevation would work, but I would prefer a contour plot. I read the
portion of David's website regarding contour plots(
http://www.dfanning.com/color_tips/fill_colors.html ), but I'll admit
that a lot of that code was over my head. I'm very new to programming
in IDL, and have a rudimentary (at absolute best) understanding of
using colors.
Any thoughts are appreciated!
