#165737 — Linux CLI gnuplot-ish program to do maps?

Is there a Linux CLI gnuplot-ish program to do maps?

For example, one puts in a file that one wants a black
and white PNG not bigger than some size, showing the
Pacific Ocean including Hawaii and Easter Island?

I think gmt (Generic Mapping Tools) will do that kind of thing. I
suspect it has a tough learning curve (but then I've never put in the
effort to learn gnuplot, either).

gtm seems to be exactly what I seek and a *wonderful*
program!

Only two problems:

    1. I've yet to find a simple 'hello world'
       (!) example.

    2. The many complicated examples (earthquakes and
       so on) I've found I cannot execute, as I don't
       have the *data*.

As you say on K2 Summit day when you are first in line
with 20 people behind you: "Hey ­ where is the gear?
Where is the equipment?"

Uh-oh!

I have now found gmane.comp.gis.gmt.user, God willing
they will be the right persons to help me.

I have now learned that:

    The old gmt-help list is no longer active.
    Please use the User forum on gmt.soest.hawaii.edu

Bad move, but what the heck.

Take a look at the BRL-CAD DSP tutorial here:

  http://brlcad.org/wiki/DSP

Is that anywhere near what you want?

Best regards,

Not what I can see :)

No, I'm talking simple maps of the physical, human
world. Like the ones you would find in a Jules
Verne novel.

I did it! :)

Here is the command to get Fatu Hiva!

    gmt pscoast -R-138.75/-138.55/-10.6/-10.4 -JM6i -Pc \
    -Ba0.33/a0.33/WeSn -S0/100/200 -Ggray -Dh           \
    -W0.1 > fatu-hiva.ps

The result (the PNG after convert(1)):

    http://user.it.uu.se/~embe8573/pics/fatu-hiva.png
    http://user.it.uu.se/~embe8573/pics/fatu-hiva.ps

Still, not much of a map tho... I'll have to figure
out how to add the villages... and mountains... and
moais... and aku-akus!

But it is possible, just like I knew that it would be! :)
