Support for .LAZ

As a Lidar novice, it seems like it would be ideal if .LAZ files could be supported directly in Pro instead of needing to convert each .LAZ file to .LAS.

Support for referencing LAZ files from the LAS dataset is planned for Pro 3.6.

Hi @ClaytonCrawford , our Federal customers would also like to see direct support for LAZ files in Pro. So thank you for following this one. Question: your response seems to include a nuance I don't know if I'm interpreting correctly. It suggests that an LAS file will need to be available separate from the LAZ (compressed version of the LAS). Whereas, by "direc support" I believe the Original Poster and our customers would like Pro to read and work with LAZ files directly (handle the decompression under the hood for the portions being utilized is what I would think would happen). Is that what is/will be available in Pro 3.6? Thanks for your attention to this matter.

@JTessier a LAS file will not need to be available separate from the LAZ. You can reference and consume one or more LAZ files/tiles directly from a LAS dataset (*.lasd).

Supported in Pro 3.6. Added ability to reference and read LAZ format LAS files when referenced by LAS dataset (*.lasd).
