Hi Thomas, By zones I assume you mean regions in your geotiff defined by uniform cell values.
If you create a GridCoverage2D object from your geotiff you could then turn the value zones into vector polygons using the PolygonExtractionProcess class which is part of the gt-process-raster module: https://github.com/geotools/geotools/blob/master/modules/unsupported/process-raster/src/main/java/org/geotools/process/raster/PolygonExtractionProcess.java Although this class is set up to be used as a process called by an application, you can also use it "manually" by creating an instance and calling its execute method. Once you have the polygons (returned from the process as a feature collection) you could intersect these with your shapefile polygons and save the result polygons in whatever form you want (e.g. create another feature collection and write to a new shapefile). Hope that it is enough to get you started.
