I have imported LiDAR data into ArcMap in the shape of a Las DataSet with twelve .las files (contains over 100 million data points).

I believe the file itself is working properly. However, no points are drawn in ArcMap (“Data percentage: 0”) unless I zoom to a very small area. I believe this is a result of the las files containing too much data with over five million points each.

I have tried:

  • Setting the point limit to five million.
  • Changing the point density to course.
  • Filtering out certain points.

But to no avail.

Is there some other way to make the LiDAR data display (at least to some extent) in full view?

Maybe by lowering the number of data points.

    That behavior is what I would expect. Have you seen ESRI's scalability help on the subject? desktop.arcgis.com/en/arcmap/10.3/manage-data/las-dataset/… – johns Mar 26 '18 at 12:33
  • Yes, I have read it. As I said, I don't see any points at all in ArcMap, maybe because of outrageous loading times. What I want to do is either lowering the resolution or reduce the actual number of points in the point cloud (the las files contains over 100 million data points). I want the lidar data to be visible in it's full geographical extent and not just small areas. – Linebeck Mar 26 '18 at 13:25
  • Have you looked at the LAS to Multipoint or LAS to Raster tools in ArcGIS? – johns Mar 26 '18 at 16:57
  • Yes. I have now converted the point cloud to a DEM which is a bit easier to worked with. – Linebeck Mar 27 '18 at 18:52
  • I highly recommend plas.io for simple visualization. – Aaron Apr 6 '18 at 15:57

Depending on the size of the LiDAR point data, I would use an alternative software specifically for that. I usually use ArcSCene to view in 3D, but for larger size LiDAR data, I use CloudCompare. It is an open source software and very powerful.

  • Maybe that's the only solution... or buying a more powerful computer. – Linebeck Mar 27 '18 at 18:51
