CloudCompare forum

Good afternoon,

I am working with point clouds generated through LiDAR sensors and need to retain all the information that comes with the point cloud. The issue is that I usually work with multiple files simultaneously, and it takes me more than a day to finish the processing. For this reason, I often save the entire workspace in `.bin` format. However, the problem arises when I need to use the GPS time, as it gets lost along with the shift when saving and reloading in `.bin` format (if I save it in the original LAS/LAZ format, there is no issue). I am attaching images to demonstrate the problem.

My question is as follows: Is there any way I can recover the original GPS time? I have tried entering the value when loading the file, but the number has more digits than I can input, and the resulting histogram becomes distorted. Is there any tool within the software that I can use to reset it to the value I need?

Thank you very much,
Jose Manuel Plata

Which version are you using? That's the first time such an issue with the BIN format is reported. Can you maybe share with me a small sample file with the issue? (you can send it to admin@cloudcompare.org).

If the bug is confirmed, and if you have a lot of impacted files, I guess we could think of adding something to fix the issue.

Anyway, and that should solve your issue completely in the future, but the next version of CloudCompare won't rely on any explicit shift of the GPS (or other large) scalar values. You can test it here:

Don't hesitate to test it and see if it solves the issue.
