      Description

      Hello,

      when using wps to download raster data, ability to select individual bands from the original raster can be useful. This would be an improvement of the wps-download module for raster in order to reduce download size.

      The download process should be extended to have a new optional parameter to select the output bands:

      @DescribeParameter(name = "selectedBands", description = "Band indices", min = 0) int[] bandIndices,

      If set, the process will perform a band select before generating the output file. In case non existing bands are requested, a clear error message should be reported back to the user. In GeoServer a process that can perform a Band Select on a raster already exists and can be integrated into the current download process execution for raster datasets.
