Fellow GU/GP's:
Is anyone else out there using Generic Mapping Tools (GMT) to create
high quality output from GRASS. It runs from the command line and a number of
variables can be adjusted for mapping as required. It can be ftp'd from
kiawe.soest.hawaii.edu, get the tar file GMT.tar.Z form the pub/gmt directory.
It appears to have a number of different projection capabilities that
would prove useful to our organization. Only problem is that it uses
netCDF formatted gridded data. One can get a data set out of GRASS well
enough via r.out.ascii, but in GMT it will only import tri-collumn (xyz) data,
and not flat ascii grids.
Has anyone already written a conversion utility to go from flat
ascii grid to a netCDF format?
I was thinking of using this since other people in our group indicated
that the MAPGEN documentation at charon.er.usgs.gov was outdated and a
nightmare to sort through.
Any comments on either of the above packages would be appreciated.

is this what you're looking for?
r.stats -1x

I agree that this is not put together well, esp when it comes
to multiple platforms.

let us know how GMT does - if possible, perhaps you could
leave an output file lying around showing us the capabilities...
or is there something like this on the site in hawaii?
[g.gnuplot plug follows]
personally, I've been using g.gnuplot so that I can output rasters,
vectors, sites, etc, in TeX or FrameMaker files (maybe using Xfig to
annotate)... g.gnuplot is on moon - the big problem that I have with
it is getting a 1:1 aspect ratio (possible, but sometimes a pain).
It's not really meant for high volume map production, but it's great,
e.g., for putting 3-D views of raster maps (surface suspended above
contours) in papers.
