GOOD DAY ALL
Please, can you help..
received this trajectory file data with our lidar dataset, but when we filter the time stamp (as being column1-208706.00806 etc as per the information received it gives us this error)
what am I going wrong or is the error in the trajectory information received
Hi All
I am having the same issues. I have received a las file and the corresponding trajectory files but get a mismatch error.
Been looking on the net to see how i can convert the SOW time to GPS time but not seen anything that works or really makes sense.
These are the time stamps i have on my .txt file and the Las file is saying it should be 1.35446e+09
Any idea what conversion method you should use or work flow. We have spoken to Bentley and DJI both say its the others problem.

Hi @ Peter Jackson. You can use LAStools: https://rapidlasso.com/lastools/
If you are struggling I can help in Terrasolid.

Thanks Jason
So Lastools should be able to solve the conversion / mismatch issue. ?
Yes, LAStools can convert your point between SOW and GPS and update the global encoding. If you need to change your trajectory I would do that in excel.
Hi, i got LiDAR dataset from Zenmuse L1, can you give me step by step how to solve the mismatch issue using lastool or excel?
Hi Eko, you need to make sure your trajectory and point cloud have the same time. You can use Las info to find out what the global encoding stamp is inside your .las file. Once this is known (in some examples I have it is 1) you need to ensure your trajectory is in the same format. See some useful links here: https://support.geocue.com/las-global-encoding-bytes-explained/ https://www.labsat.co.uk/index.php/en/gps-time-calculator
Hi, thx for the guidance, so from DJI Terra i already get the .las and sbet.txt with time in SOW as picture below
and i check with lasinfo, the global encoding is 1
so what do i do from here?? what do i need to convert? im sorry for the trouble, kinda new into this, and thx for sparing your time helping me
