Model attributes (Average Overlay)

The Average Overlay's model calculations depend on a number of keys, properties and attributes.

Keys

Icon	Key	Unit	Range	Description	Default value
	KEY	m	-3.4028235E38 to 3.4028235E38	Key used to retrieve a value from one or more Layers for a specific grid cell. Grid cell value will be averaged over the selected distance.	0

Properties

Icon	Property	Description	Default value
	Rasterization	The rasterization method of a Average Overlay	FIRST
	Maplink	The attribute maplink (layer) used to select an Key when rasterizing a Average Overlay	None (null)

Prequels

Name	Prequel	Underlying data	Unit	Range	No data	Description
INPUT	INPUT	Average Prequel		- infinity to infinity		The Grid Overlay that provides the Average Overlay with its initial values.

Attributes

Icon	Attribute	Unit	Range	Description	Default value
	DISTANCE_M	m	0 to 2000.0	The radius within which an average value must be computed.	100
	DEFAULT_VALUE			The default value used for a cell when no spatial data overlaps that cell.	0
	ATTRIBUTE_TIMEFRAMES	integer	1 to 1000	The amount of timeframes to display when basing input on Attribute arrays.	1
