Parameters

Name	Type	Default	Meaning
`Location`	`const FVector&`	—	World position, cm; Z is ignored.
`OutZ`	`double&`	—	World Z of the ground, cm.
`OutPrecision`	`EOrreryTerrainPrecision&`	—	Exact, Approximate (mip pyramid) or NoData.
`Surface`	`EOrreryTerrainSurface`	`EOrreryTerrainSurface::Modified`	Which ground to read: Modified (the default) is the ground as edited.

Returns

false when OutPrecision is NoData (outside the terrain, or no terrain).
