Howdy all, I have a set of data to store in a PostGIS database and to
use to create images. I've looked at a bathymetry example which I
grabbed from www.arsc.eu/~kate/grids/grid_cdf.ncl as well as the
native_5.ncl example on the NCL web site. I have attached a sample
topography.gif and its associated topography.nc (separate from the
ias_2010060112.nc file which is 37Mb).
Now, I'm rusty with my ncl and could use some help and/or pointers. I'm
sure someone has already worked with data like this. I'm stuck on the
lines in the example native_5.ncl script which are:
file1 = addfile(FILENAME1,"r")
field1 = file1->$FIELDNAME1$(TIME1,::-1,:)
A summary of this data looks like this:
filename: ias_2010060112.nc
