Method Detail

getGeoPos

public GeoPos getGeoPos(PixelPos pixelPos,
                        GeoPos geoPos)

Description copied from interface: ForwardCoding

Returns the latitude and longitude value for a given pixel co-ordinate.

Specified by:

getGeoPos in interface ForwardCoding

Parameters:

pixelPos - the pixel's coordinates 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 the underlying CRS

initialize

public void initialize(GeoRaster geoRaster,
                       boolean containsAntiMeridian,
                       PixelPos[] poleLocations)

Description copied from interface: ForwardCoding

Initializes the ForwardCoding. Passes in the geo_raster and allows initializing.

Specified by:

initialize in interface ForwardCoding

Parameters:

geoRaster - the geoRaster

containsAntiMeridian - whether the data crosses the anti-meridian or not

poleLocations - locations of the poles - o3 a leght zero array if no poles are contained in the data

getKey

public String getKey()

Description copied from interface: ForwardCoding

A ForwardCoding shall be instanced only by ComponentFactory using a String key. Such an instance must be able to return the key, in order to persist the ForwardCoding and recreate such an instance via ComponentFactory if the Product shall be opened again.

Specified by:

getKey in interface ForwardCoding

Returns:

the key String used while instantiating via ComponentFactory

dispose

public void dispose()

Description copied from interface: ForwardCoding

Free all resources allocated

Specified by:

dispose in interface ForwardCoding

clone

public ForwardCoding clone()

Description copied from interface: ForwardCoding

Create a shallow copy of the ForwardCoding, rasterdata is shared;

Specified by:

clone in interface ForwardCoding

Overrides:

clone in class Object

Returns:

the clone
