Terrain elevation prequel (Water Overlay): Difference between revisions

Revision as of 14:51, 3 June 2022

Name	Prequel	Underlying data	Unit	Range	No data	Description
Terrain elevation	TERRAIN_ELEVATION	Water Prequel		-10000 to 10000	Clamped to range	Used for initializing the terrain elevation on this datum.

This prequel serves as a replacement for the DTM, which is the elevation model without the Constructions. The Water Overlay will still add the heights of any Constructions present, in accordance with the set DESIGN_FLOOD_ELEVATION M.

The values in this prequel grid are clamped between -10000.0 and 10000.0. No data values are not allowed.
Any Grid Overlay used as input for this prequel should cover the 3D world completely, without any NO_DATA values. If the dataset used does contain NO_DATA values, it is prudent to use a Combo Overlay or an Average Overlay to fill up any NO_DATA values, and use that Grid Overlay as input for this prequel instead.
