Building elevation prequel (Heat Overlay)

Name	Prequel	Underlying data	Unit	Range	No data	Description
Building elevation	BUILDING_ELEVATION	Heat Prequel	m	-10000 to 10000	Clamped to range	Used for initializing the digital surface model used for this Heat Overlay.

Notes

• The values in this prequel grid are clamped between the mentioned min and max. No data values are not allowed, although negative NO_DATA values will result in a foliage height of 0. An Average Overlay can be used to fill in the NO_DATA values of an other grid overlay.
• The foliage height is a relative height value in meters. Not the datum height.
