importing .LAS datasets (LIDAR)

[DavidO_Connor]

Hello,

I have a number of .LAS files, but ArcMap is not seeing them when I go to add them.  The file type (in the normal windows view)
shows it to be the .las extension but type  'DWG TrueView Layer State'.  This is my work laptop and I also have TrueView, and I think somehow TrueView added the association.  I downloaded the files from opentopography.org

How can I change the file type or add it into ArcMap?

Thank you!

ArcMap doesn't support .las directly for display.  You have to create a LAS Dataset, then load the .las files into it (using references), then add the LAS Dataset (.lasd file) to ArcMap.  Optionally, you can load the .las files into a Mosaic Dataset and add it to ArcMap.
