Sample command: ``` **getSurfaceHeight //position//** Position: positionASL - the position where surface height is needed ``` If possible, maybe a companion command **getSurfaceNormal //position// **can also be helpful. (which returns the walkable surface normal at a 3D positionASL, not necessarily terrain normal like surfaceNormal)
