Prequels (Heat Overlay)

Prequel overlays can be linked to the Heat Overlay to initiate particular parts of the model with more accuracy and detail.

Name	Prequel	Underlying data	Unit	Range	No data	Description
Building elevation	BUILDING_ELEVATION	Heat Prequel	m (datum)	-10000 to 10000	Clamped to range	Used for initializing the digital surface model used for this Heat Overlay.
Foliage height	FOLIAGE_HEIGHT	Heat Prequel	m	0 to 100	Clamped to range	Used for initializing the relative foliage heights.
Terrain elevation	TERRAIN_ELEVATION	Heat Prequel	m (datum)	-10000 to 10000	Clamped to range	Used for initializing the digital terrain model used for this Heat Overlay.
