A result that contains a status, plus an output geometry only if the status is favorable.

Exceptions

Exception	Description
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run.

Remarks

The missingHandler will be used to determine what to do if the layer has no data at the particular input coordinate. 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 with the InputZ value.

Use CanGetZs to determine if the layer can be used as an elevation source before calling this function.
