LiDAR from USGS

[rochre]

I need to create a model of Mount Rainier so I've down loaded some LiDAR data from the USGS. It was .laz and I converted to .Las. 

I import the data with the LiDAR import node. However I don't see a point cloud for me to manipulate my height field with. I feel like I need to start trouble shooting by at least verifying the .las is importing properly. I'm not great at Houdini yet so I apologise is this is basic.

There is a search tool at the top of the forum. I think there was a recent post about importing.las files.

Thanks. I found a post with example files but they didn't with my data. My files are OK so not sure what's up.

@rochre

check that post to import LiDAR, somewhere there you find scene files to import LiDAR.
How did you convert *.*laz to *.*las? With LASzip it worked for me.
Could you upload an example of the *.*las that doesnt work?

First - You're awesome. Thanks for the help.

I did use LASzip. I found an online LiDAR visualizer so I can see the data is there. In Houdini it is reading points.

I've upload one of the las files and look through the link you posted. Thanks.

I could load your file with the LiDAR importer.

It has a big hole where are no points, but its loading.

I highly recomment that tutorial - its all about making hightfields from LiDAR - and the guy is teaching lots of awesome tricks:
