CanClassifyLasPoints Method

In This Topic

Determines whether the specified classification edit can be performed on this LAS dataset layer. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

Visual Basic (Declaration)
C#

Public Function CanClassifyLasPoints( _
   ByVal editDescription As LasPointClassificationDescription _
) As Boolean

public bool CanClassifyLasPoints( 
   LasPointClassificationDescription editDescription
)

Parameters

editDescription: The set of classification edits to apply.

Return Value

A boolean indicating that edits can be applied.

Exceptions

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

Remarks

It is important to call this method prior to ClassifyLasPoints to ensure the parameters are valid.

> This method checks that a selection exists, and that the ClassCode is a valid value for the layer (that is; it is not a value greater than the maximum allowable classification code for the layer).

Example

Classify LAS Points

// build the LasPointClassificationDescription
// assign a new classification code to be assigned to the selected LAS points
// don't alter any of the classification flags
var edits = new LasPointClassificationDescription();
edits.ClassCode = 6;

if (lasDatasetLayer.CanClassifyLasPoints(edits))
  lasDatasetLayer.ClassifyLasPoints(edits, true);


// alternatively set up the LasPointClassificationDescription to modify classification flags
var edits2 = new LasPointClassificationDescription();
edits2.KeyPoints = LasClassFlagEditType.Set;
edits2.SyntheticPoints = LasClassFlagEditType.Clear;
// don't change the OverlapPoints, WithheldPoints flags

// apply the edit
if (lasDatasetLayer.CanClassifyLasPoints(edits2))
  lasDatasetLayer.ClassifyLasPoints(edits2, true);



// or perform both a classification code and classification flag edit
var edits3 = new LasPointClassificationDescription();
edits3.ClassCode = 5;
edits3.KeyPoints = LasClassFlagEditType.Set;
edits3.SyntheticPoints = LasClassFlagEditType.Clear;
// be explicit about not changing the other flags
edits3.WithheldPoints = LasClassFlagEditType.NoChange;
edits3.OverlapPoints = LasClassFlagEditType.NoChange;

// apply the edit
if (lasDatasetLayer.CanClassifyLasPoints(edits3))
  lasDatasetLayer.ClassifyLasPoints(edits3, true);
