Ciao Ian, another option is to use the zonal stats operation or even better the process.
The operation is part of the coverage module: https://github.com/geotools/geotools/blob/12.x/modules/library/coverage/src/main/java/org/geotools/coverage/processing/operation/ZonalStats.java https://github.com/geotools/geotools/blob/12.x/modules/library/coverage/src/test/java/org/geotools/coverage/processing/ZonalStasTest.java The process is in unsupported process-raster: https://github.com/geotools/geotools/blob/12.x/modules/unsupported/process-raster/src/main/java/org/geotools/process/raster/RasterZonalStatistics.java https://github.com/geotools/geotools/blob/12.x/modules/unsupported/process-raster/src/test/java/org/geotools/process/raster/ZonalStatsProcessTest.java I'll answer on stackwhatever as well.
