HeightAboveGround tool produces invalid geotiff

[mpickering]

I am running the HeightAboveGround command with standard las file (which works for other tools) but the produced geotiff is invalid.

When opened in GIMP it reports "Not a TIFF or MDI file, bad magic number 16716.

My exact command is:

"whitebox_tools" -v --run=HeightAboveGround --input="/home/matt/win-hill-lidar/P_10684/SK1585_P_10684_20210316_20210317.las" --output="/home/matt/win-hill-lidar/height.tif"

I can provide the .laz file if you can't reproduce without it.

Sure, if you can send me the LiDAR point cloud file, that would be helpful for diagnosing the issue.

Can you try this link?

I am not sure if it will expire or is unique to me.

I've downloaded the file and can confirm that the TIFF file that is created by the HeightAboveGround tool cannot be opened in QGIS. I'll need to dig a little further into it to see what is happening.

This tool ouputs a lidar file rather than a raster hence the invalid TIFF.

That being said, there is a separate issue, at least with this file, because the resulting LAS file doesn't seem to be correctly structured. lasinfo from LAStools is reporting all sort of weird values with a probable mismatch between what the header contains and what the rest of the file contains.
