extends NOAA1bV2Reader

A NOAA 1b version 3 reader is a NOAA 1b reader that reads NOAA 1b packed format KLMNN' GAC/LAC/HRPT data files available from the NOAA/NESDIS Satellite Active Archive. These files are very similar to version 2 with some minor modifications and extensions for NOAA-N and NOAA-N' data.

Since:

3.1.9

NOAA1bV3Reader

public NOAA1bV3Reader(String file)
               throws IOException

Constructs a NOAA 1b version 3 reader from the specified file.

Parameters:

file - the file name to read.

Throws:

IOException - if an error occurred reading the file data.

Method Details

getDataFormat

public String getDataFormat()

Gets the data format description.

Overrides:

getDataFormat in class NOAA1bV2Reader

getDataFormatVersion

protected int getDataFormatVersion()

Gets the data format version.

Overrides:

getDataFormatVersion in class NOAA1bV2Reader

getDataHeader

public NOAA1bReader.DataHeader getDataHeader()
                                      throws IOException

Description copied from class: NOAA1bReader

Gets the data header.

Overrides:

getDataHeader in class NOAA1bV2Reader

Returns:

the data header.

Throws:

IOException - if an error occurred reading the file data.

getScanLine

public NOAA1bReader.ScanLine getScanLine(int line,
 int start,
 int count)
                                  throws IOException

Description copied from class: NOAA1bReader

Gets the scan line at the specified index.

Overrides:

getScanLine in class NOAA1bV2Reader

Parameters:

line - the scan line index in the range [0..lines-1].

start - the starting sensor data sample.

count - the total number of sensor data samples. If the count is 0, no sensor data is read.

Returns:
