I am attempting to view lidar point cloud data in arcgis pro. I have downloaded LAZ files from the USGS national map. Then I used the convert las tool in arcgis pro to convert the LAZ. I am using NAD 83 UTM zone 10 N as a coordinate system. When I load the converted LAS into arcgis pro the extent is in the middle of the pacific and not in northern California as it should be. Any ideas where my error is? Thanks in advance

You need to check the metadata from the Data Source. I downloaded one sample LAZ. On checking its metadata, the projection was "NAD_1983_StatePlane_California_III_FIPS_0403_Feet".

I defined the projection "NAD 1983 StatePlane California III FIPS 0403 (US Feet)" while running Convert LAS tool.

Thanks Jayanta, you were correct. The projection information was a bit buried in the metadata, thanks for helping me find it.
