John/Yuan-

I tried reading in a GINI image through the IDV.  It comes
in through the GeoGrid interface, but I see the following
issues:

- the range of data ends up being -128 to 128 instead of
0 to 255.  The variable says it's unsigned and in the
GeoGridAdapter for the IDV, we just call:

   Array arr = geoGrid.readVolumeData(timeIndex);
   Object dst       = arr.get1DJavaArray(float.class);

hmmm, i need these lower level libraries to realize the data is unsigned.
it will have to be after the stable release

Should this be returning unsigned values?

- I don't get a time associated with a particular file.
The time axis is null.  Can one be created through the
IOSP layer?

Its handled in the aggregation, for example, open this as a grid:

 dods://motherlode.ucar.edu:8080/thredds/dodsC/satellite/3.9/WEST-CONUS_4km

this is probably the way you want to see these files anyway
