Importing LAZ files doesn't work

Post by Florian »

Hi,

When importing .Laz files from the Flemish government (lidar scans they did in 2014/2015), Cloudcompare gives this error:

"PDAL exception: readers.las: reading point 2084566 of 2084547 total points"

When I press "OK" I get this message:

"An error occured while loading 'Name of the scan': the third-party library in charge of saving/loading the file has failed to perform the operation"

I am able to convert the .laz files to .las with laszip, but I was wondering if there is a solution in Cloudcompare? Or is there another solution to make these files work immediately in Cloudcompare?

I tried to put a file in attachment but the file is too large (10.2MB)

Many thanks in advance.

Can you maybe send me the file directly? (admin [at] cloudcompare.org)

Thanks, I'll investigate why PDAL fails to load this file.

Meanwhile, you can use (with the Windows version) the other LAS import filter ('LAS 1.3 or 1.4') that relies on LASlib.

Hi everyone,

I'm having the same issue/error to open large point cloud Laz files (~600 million points/ 8GB) generated using LASlib (LAZ Format 1.4).
Las files open as expected for 600 million points and smaller point cloud laz files generated by the same method open ok too (~15 million points)

ERROR:
PDAL exception: readers.las: reading point 0 of 584564737 total points
An error occurred while loading '200218_203502': the third-party library in charge of saving/loading the file has failed to perform the operation

Any solution so far?

Can you maybe open an 'issue' on github? Or maybe ask directly to the PDAL team?

Hi Mariana,
I am having the same problem that you report. Did you solve it?
