Surface elevation result type (Water Overlay)

Icon	Result type	Unit	Mode	Description
	SURFACE_ELEVATION	m + datum	Start	The rasterized version of the terrain height for use in the water overlay's calculations.

Notes

• By design, the values displayed by the elevation result type may differ from the heightmap as shown by the Heightmap Overlay. Where the heightmap forms the base height information for the project in general, the elevation result type shows the way the terrain height is interpreted specifically for the Water Overlay. This means smoothing out extremely sharp inclines, emphasizing waterways when grid accuracy is lower, and taking into account the height changes due to breaches.
