NOAA1bFileReader

public NOAA1bFileReader(String fileName)
                 throws IOException

Creates a new reader assuming big endian byte order.

Parameters:

fileName - the NOAA 1b filename.

Throws:

IOException - if an error occurred reading the file.

NOAA1bFileReader

public NOAA1bFileReader(String fileName,
 boolean isByteSwapped)
                 throws IOException

Creates a new reader.

Parameters:

fileName - the NOAA 1b filename.

isByteSwapped - the byte swapped flag, true if the data is in little endian byte order.

Throws:

IOException - if an error occurred reading the file.

Method Details

getDataFormat

public String getDataFormat()

Description copied from class: EarthDataReader

Gets the data format description.

Specified by:
