to LAStools - efficient tools for LiDAR processing
Hi everybody,
I am a newer to use LAStools, and trying to convert a .txt file to a .las file.
the commands I used like this:
I am a newer to use LAStools, and trying to convert a .txt file to a .las file.
the commands I used like this:
txt2las.exe ^
-i input.txt -o output.las ^
-set_version 1.3 ^
-parse xyz0123456789 ^
-add_attribute 6 "Intensity" "intensity description" ^
-add_attribute 5 "AxesX" "AxesX description" ^
-add_attribute 5 "AxesY" "AxesY description" ^
-add_attribute 5 "Increment" "Increment description" ^
...
-add_attribute 4 "Note" "reserved column"
I used the '-add_attribute' to store extra custom column-values, but it mostly tolerate 10 extra-customs..(-parse xyz0123456789)
And I haven't found the better solutions for this......
I would appreciate any help :-)
And I haven't found the better solutions for this......
Is it possible to store extra custom-columns more than 10?(actually I have 12 extra-columns..)
I would appreciate any help :-)
Kind regards,
Jung

Hello Jung,
thanks for your motivation with supporting more additional attributes via the "extra bytes" functionality. The next version of txt2las will support up to 32 additional attributes.
Note you'll need to either wait for the next version for this to work or use these tools here:
Here an example of how to use it with 12 additional attributes per point that works with the file "testData.txt" that is attached to this email.
