Re: [Geotools-gt2-users] Fwd: Creating an empty GridCoverage2D

[Simone G. <sim...@gm...>]

I guess the easiest thing to do is first create an empty image and
then feed it to a gridcoverage factory.

Easiest way to create an empty raster with some initial values for
each band is the Constant JAI operator.
See  http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/javax/media/jai/operator/ConstantDescriptor.html.

Regards.
