Method Details

createPixelGeoCoding

public static ComponentGeoCoding createPixelGeoCoding(Band latBand,
 Band lonBand,
 double rasterResolutionInKm)
                                               throws IOException

Creates a ComponentGeoCoding using a PixelForward and a PixelQuadTreeInverse coding using the Bands passed in and the given ground resolution. The ComponeneGeoDoding is returned is initialized and ready to use.

Parameters:

latBand - the Band containing the latitude data

lonBand - the Band containing the longitude data

rasterResolutionInKm - the ground resolution in km

Returns:

a ready to use GeoCoding

Throws:

IOException - on disk IO errors

createPixelGeoCoding

public static ComponentGeoCoding createPixelGeoCoding(Band latBand,
 Band lonBand)
                                               throws IOException

Creates a ComponentGeoCoding using a PixelForward and a PixelQuadTreeInverse coding using the Bands passed in. The ground resolution is estimatesd from the geolocation data. The ComponeneGeoDoding is returned is initialized and ready to use.

Parameters:
