Class RADRnav
java.lang.Object
edu.wisc.ssec.mcidas.AREAnav
edu.wisc.ssec.mcidas.RADRnav
- All Implemented Interfaces:
- java.io.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.

RADRnav
public RADRnav(int[] iparms)
throws java.lang.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:
java.lang.IllegalArgumentException
- if the nav block is not a RADR type.
toLatLon
public double[][] toLatLon(double[][] linele)
- converts from satellite coordinates to latitude/longitude
- Specified by:
toLatLon
in class AREAnav
- Parameters:
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.)
- 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
- Parameters:
latlon[][]
- array of lat/long pairs. Where latlon[indexLat][]
are latitudes and latlon[indexLon][] are longitudes.
- 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(java.lang.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
