ArcGIS.Desktop.Mapping Namespace / Map Class / GetZsFromSurface Method / GetZsFromSurface(Geometry,ElevationSurfaceLayer,SurfaceZsMissingHandler) Method
the input geometry
identifies the surface to be used - if specified null, then the default Ground Surface will be used
provides options to handle missing Zs in the surface
Version

GetZsFromSurface(Geometry,ElevationSurfaceLayer,SurfaceZsMissingHandler) Method
Obtains a geometry that is similar to the given input geometry, where some or all Z values are populated from the specified Elevation Surface Layer.
Syntax

Parameters

geometry
the input geometry
surfaceLayer
identifies the surface to be used - if specified null, then the default Ground Surface will be used
missingHandler
provides options to handle missing Zs in the surface

Return Value

A result that contains a status, plus an output geometry only if the status is favorable.
Exceptions
ExceptionDescription
The input geometry is null.
This Map does not have the specified surfaceLayer.
This Map does not have a default Ground Surface (when surfaceLayer is null)
This Map does not have a CIM definition.
This Map does not have any surfaces.
Remarks
The missingHandler will be used to determine what to do if the surface has no data at a particular input geometry point. The corresponding output geometry point or vertex Z will be set to the value specified in the provided missingHandler.OutputZ property. The missingHandler.OnlyProcessMissingZs parameter can be used to overwrite all Z values or only those that are designated as missing based on a comparison the InputZ value.
