Class RADRnav

java.lang.Object
  edu.wisc.ssec.mcidas.AREAnav
      edu.wisc.ssec.mcidas.RADRnav

All Implemented Interfaces:

Serializable

public final class RADRnav

extends AREAnav

Navigation class for Radar (RADR) type nav. This code was modified from the original FORTRAN code (nvxradr.dlm) on the McIDAS system. It only supports latitude/longitude to line/element transformations (LL) and vice/versa. Transform to 'XYZ' not implemented.

Constructor Detail

RADRnav

public RADRnav(int[] iparms)
        throws IllegalArgumentException

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

Parameters:

iparms - the nav block from the image file

Throws:

IllegalArgumentException - if the nav block is not a RADR 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/long 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);

toLatLon

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

converts from satellite coordinates to latitude/longitude

Overrides:

toLatLon in class AREAnav

Returns:

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

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);

equals

public boolean equals(Object o)

Description copied from class: AREAnav

Determines whether or not the Object in question is the same as this AREAnav. Right now, this returns false until we can figure out when two navigations are equal. Subclasses could override if desired.

Overrides:

equals in class AREAnav

Parameters:

o - the AREAnav in question
