FastMapHistogramVisitor

object FastMapHistogramVisitor

Visitor that constructs a FastMapHistogram of visited values

Each visited value is given a weight of 1 in the histogram.

Implementations provided for Raster[(Tile, MultibandTile)]

This visitor skips row/col positions with NaN values.

NOTE: This visitor is provided as a convenience for small datasets and for testing. For larger applications you almost certainly want StreamingHistogramVisitor which can handle unbounded inputs.
