Las v1.4 classes reclassified to 0

Cesium ion

Does Cesium Ion support las version 1.4. I’m having issues with point clouds that have higher classifications that 20 being reclassified to 0 during it’s import.

Yes, we support the LAS 1.4 spec.

Could you give me the asset ID of your point cloud data, and I can take a closer look at what is happening with your classification values?

Thanks

Thanks, I’ll take a look.

I’ve identified an issue with LAZ file handling.

You can use laszip from https://lastools.github.io/ to decompress your file to LAS and upload that. The expected classification values should be there.

That should get you going until we can address this and put out a new release.

Thanks

We have a fix that should be released early May.

Until then you can use the LAS workaround.

Thank you for bringing this to our attention.
