Hi there,
I have received some FWF data in WGS84 zone 60S with an offset
Is this offset “fixable”? Do we think that the offset is created when the data is exported from Trimble LPMaster? Or may be the offset is from the raw files, something to do with the sensor?
I have uploaded a sample file here
And this is the script that I was using
set FWF=R:\Fullwaveform
set OUTPUT=R:\Fullwaveform
lasview -i %FWF%\*.las
lasinfo.exe -i %FWF%\*.las -odir %OUTPUT% -otxt
:: I didn’t repair the boundary box -repair_bb
laszip.exe -i %FWF%\*.las -waveform -o %OUTPUT%\cld_170704_01_223748_001_zipped.laz
las2las.exe -i %FWF%\*_zipped.laz -rescale 0.01 0.01 0.01 -remove_vlrs_from_to 4 10 -o %FWF%\cld_170704_01_223748_001.laz
lasinfo.exe -i %FWF%\cld_170704_01_223748_001.laz -odix _compress -odir %OUTPUT% -otxt
Thanks

Hi Martin,
Thank you for your answer.
All WDP file that now are corrupted after the compression, can be revers?
Thanks
Susana

The waveform packet data are stored in the LAS file in an Extended Variable Length Record or in an auxiliary *.wdp file. The Byte Offset represents the location of the start of this Point Record's waveform packet within the waveform data variable length record (or external file) relative to the beginning of the Waveform Data Packets header.
The packet of Raw Waveform Amplitude values for all records immediately follow this VLR header. [...]

Hi Martin (and Evon),
Thanks for all your help.
Yes, I still have the originals (7 disks of 6TB each)
It’s all good, thanks again.
