Logistic decay function
WitrynaLogisticDecay — Rescale input data using a logistic decay function.Used when small input values are most preferred. As the values increase, the preferences rapidly decrease, until the preferences taper off at the larger input values. Minimum —The default is the minimum of the input raster.
