    On tiling more than a single MultibandTile may get into a group that correspond to the same key.

    On tiling more than a single MultibandTile may get into a group that correspond to the same key. By default the tiledLayerRDD function flattens all bands and converts every group into a single MultibandTile. To override this behavior it is possible to set the partitionTransform function, i.e.:

    partitionTransform = {
  case iter if iter.nonEmpty => iter.map(_.tile).reduce(_ merge _)
  case _                     => MultibandTile(Nil)
}
