Help for NS001
NS001 is the logging procedure for data acquired from the NS001
multispectral scanner. The NS001 scanner is an 8 channel instrument with 7
bands in visible and near-IR and a single thermal-IR band. Its bandpasses are
similar to the LANDSAT-TM system, with an added band at 1.0 to 1.3 microns. The
NS001 scanner was designed to be operated from an aircraft platform, and scenes
are typically acquired from a C-130 operated by NASA AMES.
This TAE procedure separates the input data file into separate files for
each band logged, adds the standard annotation for NS001 data, (optionally)
performs GRADREM for brightness gradient correction, (optionally) prints the
histograms, and makes aspect and panorama corrections by means of the C130RECT
program. The user may choose to log all bands, or only a subset of the bands.
The user is required to specify the following information when running
NS001:
the input dataset name
the output dataset(s)
the flight number, line/run number, and date of the data acquisition
