All Implemented Interfaces:
GeoCoding

public class CombinedFXYGeoCoding extends AbstractGeoCoding
A geo-coding based on a combination of GeoCodings. All the geocodings added must be wrapped in a CodingWrapper which describes the area in scene coordinates to which the geocoding is concerned.

    • getCodingWrappers

      public CombinedFXYGeoCoding.CodingWrapper[] getCodingWrappers()
      Returns the CodingWrappers this GeoCoding consists of.
      Returns:
      array of CodingWrappers.
    • transferGeoCoding

      public boolean transferGeoCoding(Scene srcScene, Scene destScene, ProductSubsetDef subsetDef)
      Transfers the geo-coding of the srcScene to the destScene with respect to the given subsetDef.
      Specified by:
      transferGeoCoding in class AbstractGeoCoding
      Parameters:
      srcScene - the source scene
      destScene - the destination scene
      subsetDef - the definition of the subset, may be null
      Returns:
      true, if the geo-coding could be transferred.
    • canClone

      public boolean canClone()
      Description copied from class: AbstractGeoCoding
      Check if geocoding can be cloned.
      Specified by:
      canClone in interface GeoCoding
      Overrides:
      canClone in class AbstractGeoCoding
      Returns:
      if so or not
    • clone

      public GeoCoding clone()
      Description copied from class: AbstractGeoCoding
      Creates a shallow clone of this geocoding. Geolocation raster data is shared.
      Specified by:
      clone in interface GeoCoding
      Overrides:
      clone in class AbstractGeoCoding
      Returns:
      the cloned geocoding
    • isCrossingMeridianAt180

      public boolean isCrossingMeridianAt180()
      Description copied from interface: GeoCoding
      Checks whether or not the longitudes of this geo-coding cross the +/- 180 degree meridian.
      Returns:
      true, if so
    • canGetPixelPos

      public boolean canGetPixelPos()
      Description copied from interface: GeoCoding
      Checks whether or not this geo-coding can determine the pixel position from a geodetic position.
      Returns:
      true, if so
    • canGetGeoPos

      public boolean canGetGeoPos()
      Description copied from interface: GeoCoding
      Checks whether or not this geo-coding can determine the geodetic position from a pixel position.
      Returns:
      true, if so
    • getPixelPos

      public PixelPos getPixelPos(GeoPos geoPos, PixelPos pixelPos)
      Description copied from interface: GeoCoding
      Returns the pixel co-ordinates as x/y for a given geographical position given as lat/lon.
      Parameters:
      geoPos - the geographical position as lat/lon in the coordinate system determined by GeoCoding.getGeoCRS()
      pixelPos - an instance of Point to be used as return value. If this parameter is null, the method creates a new instance which it then returns.
      Returns:
      the pixel co-ordinates as x/y
    • getGeoPos

      public GeoPos getGeoPos(PixelPos pixelPos, GeoPos geoPos)
      Description copied from interface: GeoCoding
      Returns the latitude and longitude value for a given pixel co-ordinate.
      Parameters:
      pixelPos - the pixel's co-ordinates given as x,y
      geoPos - an instance of GeoPos to be used as return value. If this parameter is null, the method creates a new instance which it then returns.
      Returns:
      the geographical position as lat/lon in the coordinate system determined by GeoCoding.getGeoCRS()
    • getDatum

      public Datum getDatum()
      Description copied from interface: GeoCoding
      Gets the datum, the reference point or surface against which GeoPos measurements are made.
      Returns:
      the datum
    • dispose

      public void dispose()
      Description copied from interface: GeoCoding
      Releases all of the resources used by this object instance and all of its owned children. Its primary use is to allow the garbage collector to perform a vanilla job.

      This method should be called only if it is for sure that this object instance will never be used again. The results of referencing an instance of this class after a call to dispose() are undefined.
