[Re: NetCDF Question]



I wish I had a nickel for every time I asked for help only to answer my own question right after I send the email... ;-)

I serendipitously found (from a ClassCastException) that I can cast the domain set of my FlatField as a LinearLatLonSet and then use the getX() and getY() methods to obtain the values from my netCDF file.

LinearLatLonSet dSet = (LinearLatLonSet)terrainData_ff.getDomainSet();
float[][] lonSamples = dSet.getX().getSamples();
float[][] latSamples = dSet.getY().getSamples();



Tom, I just received your email and I think we're pretty much on the same page.

Thanks and sorry for the wasted bandwidth!!

Greetings,

I've been searching the email archives for a couple of days now and
cannot seem to find (or perhaps understand) a solution to the following:

I have a netCDF file that I can open up in a visad Plain and it gives me
the FlatField ((Longitude, Latitude) -> Altitude).  I would like to get
the X and Y dimension *values* from my netCDF file.

(Performing a getDoubles() or getSamples() on the domain set results in
an index-order array of lat/lon points, i.e. XxY points, and I'm
interested in creating a rectangle of points that outlines my lat/lon
domain.  I've noticed, the ucar.unidata.geoloc.LatLonRect class, but was
hoping to use the "raw" data from my files.)

Can someone get me pointed in the right direction on this?

Thanks!!

-kevin.
