RES: [Mapserver-users] GMT and netCDF

[Murilo Lacerda Yoshida]

  I was planning to use the grid tools of GMT to interpolate a map, GMT
has some tools to do it.
  The problem is that I don't know how to translate my shape files into
a valid GMT input. You said you spent a lot of time into it... Can you
help me?
  I need to translate shape files to netCDF files, use these files as
input for GMT, get the result and translate it back to shape files.
  Thanks,
    Murilo

If you think of a NetCDF file as a Fortran-formatted data file, it will 
start making sense. GMT is a good tool for grid data, and works well for

  producing some maps, but it's not designed to do what Mapserver does.

They're not the same thing, they are tools for different purposes.

For what it's worth, I spend a LOT of time with netCDF files, read them,

put the data in postgres db's and then make shapefiles from them.
