Class ABINnav

java.lang.Object

edu.wisc.ssec.mcidas.AREAnav

edu.wisc.ssec.mcidas.ABINnav

All Implemented Interfaces:

java.io.Serializable

public class ABINnav
extends AREAnav

ABINnav is used to provide "navigation" for ABIN image data. This code is essentially a direct port of nvxabin.dlm from McIDAS-X. Note: the variable naming convention has been retained from the original McIDAS-X source code.

Constructor Detail

ABINnav

public ABINnav(int[] navblock)

Initializes the ABIN navigation code with the given set of navigation parameters.

Parameters:

navblock - Navigation parameters from image file.

Throws:

java.lang.IllegalArgumentException - if navblock is not ABIN.

Method Detail

toLatLon

public double[][] toLatLon(double[][] linele)

Convert satellite lines/elements to latitude/longitude coordinates.

Specified by:

toLatLon in class AREAnav

Parameters:

linele - Array of line/element pairs. Where linele[indexLine] are "lines" and linele[indexEle] are "elements". These coordinates must be "file" rather than "image" coordinates.

Returns:

Array of latitude/longitude pairs. latlon[indexLat] are latitudes and latlon[indexLon] are longitudes.

toLinEle

public double[][] toLinEle(double[][] latlon)

Convert latitudes/longitudes to satellite lines/elements.

Specified by:

toLinEle in class AREAnav

Parameters:

latlon - Array of latitude/longitude pairs. Where latlon[indexLat] are latitudes and latlon[indexLon] are longitudes.

Returns:

Array of line/element pairs. linele[indexLine] are lines and linele[indexEle] are elements. These coordinates are "file" rather than "image" coordinates.
