EstimatePointSpacing Method

In This Topic

Gets the minimum, maximum, and mean point spacing estimates based on the LAS files whose extents intersect the envelope. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public ValueTuple<double,double,double> EstimatePointSpacing( 
   Envelope envelope
)

Public Function EstimatePointSpacing( _
   ByVal envelope As Envelope _
) As ValueTuple(Of Double,Double,Double)

Parameters

envelope: The envelope. It will be projected into the spatial reference of the LAS dataset.

Return Value

The minimum, maximum and mean point spacing.

Exceptions

Exception	Description
System.ArgumentNullException	envelope cannot be null.
ArcGIS.Core.Data.Exceptions.GeodatabaseException	A geodatabase-related exception has occurred.
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run

Remarks

If only one file is within the extent then the minimum, maximum, and mean values will be the same. If multiple files are intersected the minimum is set to the file with the smallest spacing, maximum to the one with the largest, and mean is based on estimating the total points within the envelope. Point spacing estimates at this level (i.e., the dataset) are based on estimates made per LAS file. They'll be more reliable if statistics for the LAS dataset have been calculated.

Requirements

Target Platforms: Windows 11, Windows 10

ArcGIS Pro version: 3.2 or higher.
