Hi Jody, Jon, > For reference here is the sample code I ended up with: > GridCoverage2D gradient = (GridCoverage2D) > Operations.DEFAULT.gradientMagnitude( dem ); > RenderedImage rawImage = gradient.getRenderedImage(); > > ImageWorker worker = new ImageWorker( rawImage ); > worker.binarize(maxSlope); > > RenderedImage processed = worker.getRenderedImage(); > GridCoverageFactory fac = CoverageFactoryFinder.getGridCoverageFactory(null); > > GridCoverage2D slope = fac.create( "slope", processed, dem.getEnvelope() );
Yep. That's pretty much how I do it. Jon's method of resorting directly to JAI will accomplish the same thing that ImageWorker does. It looks like you can also use org.geotools.coverage.processing.BilevelOperation giving "binarize" as the operation name to the constructor. I haven't tried this approach - just found it by grepping the source. It's fairly well camouflaged from users :-( Michael ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
