DK11 for ActiveX | TatukGIS_XDK11.TGIS_ViewshedObserverElevation | Enums
Specifies what is used as elevation of the observers in the viewshed or Fresnel zone clearance analysis. Elevation can be modified with an offset attribute field/value.
// C# public enum TGIS_ViewshedObserverElevation { Z = 0, M = 1, ZM = 2, OnDem = 3, OnDemPlusM = 4, Zero = 5 }

// Oxygene type TGIS_ViewshedObserverElevation = public ( Z = 0, M = 1, ZM = 2, OnDem = 3, OnDemPlusM = 4, Zero = 5 );
Name | Value | Description | |
---|---|---|---|
Z | 0 | Elevation is the Z coordinate. | |
M | 1 | Elevation is the M coordinate. | |
ZM | 2 | Elevation is the sum of the Z and the M coordinate. | |
OnDem | 3 | Elevation is read from the underlying Digital Elevation Model (DEM). | |
OnDemPlusM | 4 | Elevation is read from the underlying Digital Elevation Model (DEM) plus the M coordinate. | |
Zero | 5 | Elevation is zero; useful if elevation should be offset-based. | |
