MoveNext Method (LasPointCursor)

In This Topic

Advances to the next LasPoint in this LasPointCursor. This method must be called on the MCT. Use QueuedTask.Run.

Syntax

C#
Visual Basic (Declaration)

public bool MoveNext()

Public Function MoveNext() As Boolean

Return Value

true if the cursor has successfully advanced to the next point; false if the cursor has passed the end of the collection.

Exceptions

Exception	Description
System.InvalidOperationException	This instance has already called MoveNextArray. Call Reset before using this method.
ArcGIS.Core.Data.Exceptions.GeodatabaseException	A geodatabase-related exception has occurred.

Remarks

If MoveNext() returns true, a LasPoint object is created. Even if this point (Current) is not otherwise needed, it should be properly disposed through a call to System.IDisposable.Dispose or with the use of a using statement.

Example

Search LAS Points

// search all points
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDataset.SearchPoints(null))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}

// search within an extent
ArcGIS.Core.Data.Analyst3D.LasPointFilter pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
pointFilter.FilterGeometry = envelope;
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDataset.SearchPoints(pointFilter))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}

// search within an extent and limited to specific classification codes
pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
pointFilter.FilterGeometry = envelope;
pointFilter.ClassCodes = new List<int> { 4, 5 };
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDataset.SearchPoints(pointFilter))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}

Search for LAS Points

// searching on the LasDatasetLayer will honor any LasPointDisplayFilter

// search all points
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDatasetLayer.SearchPoints(null))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}

// search within an extent
ArcGIS.Core.Data.Analyst3D.LasPointFilter pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
pointFilter.FilterGeometry = envelope;
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDatasetLayer.SearchPoints(pointFilter))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}

// search within an extent and limited to specific classification codes
pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
pointFilter.FilterGeometry = envelope;
pointFilter.ClassCodes = new List<int> { 4, 5 };
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDatasetLayer.SearchPoints(pointFilter))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}
