MultibandTileCombineVisitor

abstract class MultibandTileCombineVisitor[R] extends GridVisitor[Raster[MultibandTile], Array[R]]

A helper for constructing visitors for Raster[MultibandTile] as long as R conforms to Cats.Monoid

In other words, as long as you can define a empty state and a combine operation on your type R, this visitor can automatically generate a Visitor for polygonal summaries on your type R.

Note that this visitor will combine values band-wise. If you'd prefer to accumulate values in some other way, you'll need to implement your own visitor.

    Called when a result is desired by the parent implementation.

    No guarantees are made that this will only be called after all visitation is complete. As a result, this should return an iterative result as cells are visited for full compatibility.
