AltitudeClamping
Altitude clamping.
Definition qgis.h:3671
@ Relative
Elevation is relative to terrain height (final elevation = terrain elevation + feature elevation)
AltitudeBinding
Altitude binding.
Definition qgis.h:3684
@ Vertex
Clamp every vertex of feature.
Line string geometry type, with support for z-dimension and m-values.
