Re: making filled shapes with MAP/BND in areas outside the US

You may want to use GMT (free, as in free beer) from U of HI to create your background map, then plot your navigated image without maps, set the color black as transparent on the resulting gempak image, and then use imagemagick to overlay the gempak image on the GMT created basemap.

Subject: making filled areas outside the US


Thanks for your responses. A few more things for all you experts--I think
it's fairly simple, but I can't seem to find the right combo of commands...

1) I have a simple black-background map with white lines for political
borders...I want to fill (colorize) the interior [land] of all of the
political border shapes just leaving the water black.  I was able to use
commands like the following to fill in, for example, the
great lakes and California, but it doesn't work for countries other than
the US?

$mapfil = hipowo.cia
BND = great_lakes/4 + state_bnds|<STATE>CA/13

However, I'd like to be able to do things like make a map of:
- the world with every country filled in solid white, water bodies in
black. - the Caribbean with just Cuba filled in solid white, but other
countries only outlined in white.

Any idea how to do that?

2) One other pitfall is that MAP and BND write on TOP the data, but I'd
like it to be below the data. I saw a reference in the tutorial about doing
filled overlays, but no matter what I changed, nothing seemed to work.
Here's the excerpt from:

  "When using filled areas as overlays, a COLOR of 0 will prevent the
filled area from blocking out graphics beneath for the value associated
with that COLOR. In many cases you will want to use filled areas as the
base image with other values plotted on top."

Exactly which variable's "color" setting is that referring to? LINE? MAP?
BND? Or am I missing something?

Thanks in advance,
