    • ScanLineV2

      public ScanLineV2(int line, int start, int count) throws IOException
      Creates a new dataset scan line using the specified index.
      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.
      Throws:
      IOException - if an error occurred reading the file data.

  • Method Details

    • getCloud

      public byte[] getCloud()
      Description copied from class: NOAA1bReader.ScanLine
      Gets the CLAVR cloud mask data.
      Specified by:
      getCloud in class NOAA1bReader.ScanLine
      Returns:
      an array of cloud mask data values.

    • getScanTime

      public long[] getScanTime()
      Gets the scan line time data. This implementation simply returns the same time for all data samples across the scan line. A more sophisticated method would compute separate times for each sample.
      Specified by:
      getScanTime in class NOAA1bReader.ScanLine
      Returns:
      an array of time data values in milliseconds.

    • getAttribute

      public Object getAttribute(int index)
      Description copied from class: NOAA1bReader.ScanLine
      Gets a scan line attribute.
      Specified by:
      getAttribute in class NOAA1bReader.ScanLine
      Parameters:
      index - the attribute index.
      Returns:
      the attribute as an object. Primitive types are wrapped in their corresponding objects.

    • isSensorDataUsable

      public boolean isSensorDataUsable()
      Description copied from class: NOAA1bReader.ScanLine
      Gets the sensor data usability flag.
      Specified by:
      isSensorDataUsable in class NOAA1bReader.ScanLine

    • isNavigationUsable

      public boolean isNavigationUsable()
      Description copied from class: NOAA1bReader.ScanLine
      Gets the navigation data usability flag.
      Specified by:
      isNavigationUsable in class NOAA1bReader.ScanLine

    • getCalibration

      protected float[] getCalibration(int channel)
      Description copied from class: NOAA1bReader.ScanLine
      Gets the set of line-specific calibration coefficients for the specified channel. The order of coefficients is not important, as the coefficients are simply used as a "calibration" signature for use in creating count versus calibrated value lookup tables.
      Specified by:
      getCalibration in class NOAA1bReader.ScanLine
      Parameters:
      channel - the channel for calibration coefficients, [1..5].
      Returns:
      an array of calibration coefficients.

    • calibrateChannel

      public float[] calibrateChannel(int[] countData, int channel)
      Description copied from class: NOAA1bReader.ScanLine
      Calibrates channel count data to scientific units. Visible channel data is calibrated to percent albedo and thermal data to degrees Kelvin.
      Specified by:
      calibrateChannel in class NOAA1bReader.ScanLine
      Parameters:
      countData - the count data as an integer array.
      channel - the channel to calibrate, [1..5].
      Returns:
      an array of calibrated sample values.

    • getRawNavigation

      public float[] getRawNavigation(int variable)
      Description copied from class: NOAA1bReader.ScanLine
      Gets the raw uninterpolated navigation data for the specified angle variable. All angles are measured in degrees.
      Specified by:
      getRawNavigation in class NOAA1bReader.ScanLine
      Parameters:
      variable - the navigation variable.
      Returns:
      an array of raw uninterpolated navigation angles.
