Example
Access LAS Points by ID
{
// access by ID
IReadOnlyList<ArcGIS.Core.Data.Analyst3D.LasPoint> pts = lasDataset.GetPointByID(123456);
pts = lasDataset.GetPointByID(123456, envelope);
ArcGIS.Core.Data.Analyst3D.LasPoint pt = pts.FirstOrDefault();
var coordsLasPoint = pt.Coordinate3D;
var mapPointLas = pt.ToMapPoint();
}
Search LAS Points
{
// 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())
{

{
}
}
}
}
Search for LAS Points
{
// Note: Needs QueuedTask to run
{
// 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;

}

{
while (ptCursor.MoveNext())
{
using ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current;
//Use the point
}
}
// search within an extent and limited to specific classification codes
pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
