I have been given an .las file and I am trying to open and view the file and eventually convert it to a TIN. I have created an LAS dataset and imported the .las file; however, when I open the las dataset all I see is a red box. I tried converting it to a TIN but that also just gave me a box. When viewing the properties of the las dataset it says there is 3,000,000 points and displays a reasonable elevation range, so I believe the data is there. Is anyone familiar with working with las datasets in arcmap? I feel like I am missing a step in processing the data. Any help would be much appreciated.
