You need to choose a common GridGeometry. You can just invoke
GridCoverage2D.getGridGeometry() on one of your coverages, or create your own
instance. Then invoke Operations.resample(coverage, theGridGeometries) where
"Operations" is a class defined in org.geotools.coverage.processing if my
memory
serve me right.
