Method Detail

toLinEle

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

Description copied from class: AREAnav

toLinEle converts lat/long to satellite line/element

Specified by:

toLinEle in class AREAnav

Parameters:

latlon - lat and lon of points (N and E are positive)

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

Description copied from class: AREAnav

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.
