All Implemented Interfaces:

Serializable

public class GVARnav

extends AREAnav

The GVARnav class creates the ability to navigate GVAR image data. It is a math copy of the McIDAS nvxgvar.dlm code. When used with AreaFile class, set up like this:

  AreaFile af;
  try {
    af = new AreaFile("/home/user/mcidas/data/AREA0001");
  } catch (AreaFileException e) {
    System.out.println(e);
    return;
  }
  int[] dir;
  try { dir=af.getDir();
  } catch (AreaFileException e){
    System.out.println(e);
    return;
  }
  int[] nav;
  try { nav=af.getNav();
  } catch (AreaFileException e){
    System.out.println(e);
    return;
  }
  try { 
    GVARnav ng = new GVARnav(nav);  // XXXXnav is the specific implementation
  } catch (IllegalArgumentException excp) {
    System.out.println(excp);
    return;
  }
  ng.setImageStart(dir[5], dir[6]);
  ng.setRes(dir[11], dir[12]);
  ng.setStart(1,1);

Constructor Detail

GVARnav

public GVARnav(int[] iparms)
        throws IllegalArgumentException

Set up for the real math work. Must pass in the int array of the GVAR nav 'codicil'.

Parameters:

iparms - the nav block from the image file

Throws:

IllegalArgumentException - if the nav block is not a GVAR type.

GVARnav

public GVARnav(int ifunc,
               int[] iparms)
        throws IllegalArgumentException

Deprecated. Since ifunc must be 1, replaced with #GVARnav(int[] iparms). If ifunc != 1, ifunc is set to 1.

Set up for the real math work. Must pass in the int array of the GVAR nav 'codicil'.

Parameters:

ifunc - the function to do (always 1 for now)

iparms - the nav block from the image file

Throws:

IllegalArgumentException - if the nav block is not a GVAR type.

Method Detail

toLatLon

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

converts from satellite coordinates to latitude/longitude

Specified by:

toLatLon in class AREAnav

Returns:

latlon[][] array of lat/lon pairs. Output array is latlon[indexLat][] of latitudes and latlon[indexLon][] of longitudes.

toLatLon

public float[][] toLatLon(float[][] linele)

converts from satellite coordinates to latitude/longitude

Overrides:

toLatLon in class AREAnav

Returns:

latlon[][] array of lat/lon pairs. Output array is latlon[indexLat][] of latitudes and latlon[indexLon][] of longitudes.

toLinEle

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

toLinEle converts lat/long to satellite line/element

Specified by:

toLinEle in class AREAnav

Returns:

linele[][] array of line/element pairs. Where linele[indexLine][] is a line and linele[indexEle][] is an element. These are in 'file' coordinates (not "image" coordinates);

toLinEle

public float[][] toLinEle(float[][] latlon)

toLinEle converts lat/long to satellite line/element

Overrides:

toLinEle in class AREAnav

Returns:

linele[][] array of line/element pairs. Where linele[indexLine][] is a line and linele[indexEle][] is an element. These are in 'file' coordinates (not "image" coordinates);
