Syntax
IDL> DataViewer, files
Arguments
files: The definition of "files" is fairly broad. This can be the name of one or more
of the image files DataViewer can read (see below), an actual image variable,
or it can be the name of a directory containing image files that DataViewer can
read, in which case DataViewer reads all the image files in the directory. This
is an optional argument.
Data Files
Currently the DataViewer program reads the following NSIDC image data files.
nsidc-0001: DMSP-SSM Daily Polar Gridded Brightness Temperatures

Additionally, the program reads BMP, GIF, JPEG, PNG, PPM, SRF, TIFF, DICOM, or
JPEG2000 image files .
Modification History
Written by: David W. Fanning and version 1.0 released to the public 11 November 2008.
Extensively modified to read more passive microware data products from NSIDS. Changes
include better ways of handling map projection information. 17 June 2010. DWF.
Fixed problem caused by loading a configuration file before images were selected,
and fixed a problem with Coyote Library routine cgLoadCT and the way it looks
for the Brewer color table file. 28 June 2010. DWF.
