AltitudeType

Gets and sets an enum determining how the altitude is interpreted. The following are the possible values:

§   ATC_TERRAIN_RELATIVE      = 0
Places the position’s pivot point at a specified altitude above the ground.

§   ATC_PIVOT_RELATIVE           = 1
Places each point of the object at a specified altitude above the pivot point altitude, defined by its Point Altitude. The pivot is located at the center of the object.

§   ATC_ON_TERRAIN                  = 2
The altitude is ignored and the coordinate is on the terrain itself.

§   ATC_TERRAIN_ABSOLUTE    = 3
Places the position’s pivot point at a specified altitude above the terrain database vertical datum base ellipsoid.

§   ATC_3DML_RELATIVE            = 4
Places the object’s pivot point at a specified altitude above the 3DML layer.

Note:    ATC_PIVOT_RELATIVE and ATC_ON_TERRAIN values apply only for 2D shapes and polygons. ATC_3DML_RELATIVE only applies to image and text labels.
