does the extract_profile tool ignore the GpsTime attribute?

[fcespedes-pathway]

When I use the extract_profile tool, it appears that the points extracted to the .las file do not have the GpsTime data that is in the original pointcloud.
Is it a bug or do I need to pass a parameter?

I run the tool as follows:
./extract_profile.exe "E:\PointClouds\Track_A" -o "E:\tmp\retz.laz" --coordinates "{564615.531, 4405035.518, 189.464},{564663.891, 4405027.402, 189.343}" --width 50 --min-level 0 --max-level 12

and the metadata.json file: metadata.json

Seem to have similar issue...
For me it is only export Intensity attribute only, nothing else.

Haven't had the time to test it yet but looks good.

thanks for pointing me this direction, i was not able build it right now, based on the readme. Is there any specific version os msvcc, or something like that? I'll take a little bit deeper afternoon.

I'm using Visual Studio 2022. If the build tool version is the issue, maybe you could specify it explicitly

cmake ../ -G "Visual Studio 17 2022" -A x64

well it has build errors, which is suppose comes from an old version of visual studio and compiler.
ends_with (since C++20) as i've told you i'm using very old compiler. Afternoon i'll update probably gonna solve everything.

When you update, also check that platform toolset and C++ language standard are set to the latest. Sometimes C++ language standard still points to something before C++20.

after upgradeing it built fine. and looks like it works for attributes what i need (Point source id, classification,intensity) :) Thanks Markus, and thanks for Potree :)
