Jacky:

If you have the data (lat, long, values) in a text file, you can also use the
new VisAD TextAdapter to read this file directly;  it will create the
IrregularSet that Bill talked about, and can be used to plot and/or contour the
data values.  Here's what such a file might look like:

#sample file for plotting/contouring data
(Longitude,Latitude)->(temperature)
Latitude, Longitude, temperature[unit=degC]
43, -90, 15
40, -89, 12
39.3, -88, 10


An example (using Jython, although you could use the SpreadSheet, too) that
plots the data:

data=load("your_file.txt")
plot(data)

(you'll need to set the mapping for the temperature to "text" or
"isocontour"...or both...).

You can then also add a basemap using:

map=load("data/mcidas/OUTLUSAM")
plot(map)
