Pix4D survey showing Unknown Error while trying to import .las file

I am trying to import a “las” file but I got the following Error:
Analyzing 1 LAS file…
Unknown Error: Unknown Error

I am not sure why the error shows up and it comes without any further explanation. I have tried to import this LAS file into pix4D cloud and it works.

Hi @kaho,

Welcome to the Pix4D Community :handshake:.

I’m sorry to hear that you are having issues during the import of the .las file into PIX4Dsurvey.

Can you please tell me how you generated the .las file?


Nice to hear from you!!
So my .las file is generated from a vehicle mapping system including LiDAR, GNSS and cameras. I tried to put this las file onto Pix4D cloud and it works, but it is not the case in Pix4D survey.
I checked my las file version to be 1.4.

Hi @kaho,

I see you are also in contact with a colleague of mine (Yuka).

It seems that the problem lies in the fact that the point cloud is in a geocentric Coordinate Reference System (CRS). This is not yet supported in PIX4Dsurvey.

Please export your .las file using a projected CRS.

You can open a PIX4Dsurvey feature request thread requesting for support for geocentric CRS.
