Model attributes (Shadow Overlay)

The Shadow Overlay's model calculations depend on a number of calculation-wide parameters. These parameters are available as attributes of the Shadow Overlay and can be modified as such.

Icon	Attribute	Unit	Range	Description	Default value
	DATES	time in milliseconds		Dates define the amount of timeframes and are used to define the day and time for calculating sun angles.	1375444800000
	FOLIAGE_AREAS	boolean		Whether to use foliage data from Areas instead of the calculated foliage decks from functions with a foliage crown factor.	0
	MAX_SHADOW_DISTANCE	m	100 to 1000	The maximum length of a shadow.	500
	SUN_ALTITUDE	angle (0-90°)	0 to 90	The sun angle up from the horizon.	49.71
	SUN_AZIMUTH	geo angle (0-360°)	-1.7976931348623157E308 to 1.7976931348623157E308	The angle of the sun along the horizon.	140.03

Notes

• When the DATES attribute is configured for multiple timeframes, the Hourly, Sun, and Wind attributes should have an equal amount of entries. When using the Heat Overlay configuration wizard, the necessary entries are created automatically.
