Hi Nicolas,
For data that does not represent a regular grid, you would use
one of the SCAT2GRID functions. You will define the grid that you
would like to see the result on, and the function uses an
interpolation or binning operation to put the data into that grid.

I wonder if there is an easy way to grid a data from ASCII
files? I'm trying to grid station data from a list and
coordinates separated in 3 text files.
I have 3 text files: one with the stations data, one with the
latitude, one with the longitude (the lon and lat are not
regular).
So basically I'd like to create a grid from the second and third
file, and associate at each grid point the corresponding value
of the station variable.
I tried something like:
FILE/VAR=StLAT/columns=1 Stations-Lat.txt
FILE/VAR=StLON/columns=1 Stations-Lon.txt
DEFINE GRID/Y=STLAT[d=3]/Y=STLON[d=4] gdata
But the "gdata" is empty.
Any idea about how to process?
