AltitudeClamping
Altitude clamping.
Definition: qgis.h:2190
@ Relative
Elevation is relative to terrain height (final elevation = terrain elevation + feature elevation)
AltitudeBinding
Altitude binding.
Definition: qgis.h:2203
@ Vertex
Clamp every vertex of feature.
Line string geometry type, with support for z-dimension and m-values.
Definition: qgslinestring.h:45
