How do people in industry handle updating a 3D pointcloud map?

Hi everyone, I was trying to find a 3D mapping pkg to map a warehouse environment, have been using glim for mapping and hdl_slam for localization.
Wanted to know if there was some technique/pkg that would like allow the pcd map to update without stopping the operations of a bot and running the mapper again.
Found this pkg called LT_mapper(this) and also found that this has been implimented in nav2, but limited to 2D maps.

Please share you insights on this, if you have any idea about this problem of updating the pointcloud map.

Thanks in advance
(PS first time posting, sorry in advance if the category)

I am not in industry, but this repo may be of interest to you:

I don’t know anything about 3D mapping, but I’ve been running an experiment with an index to ROS nodes. This list of nodes in Rolling that reference PointCloud2 might be of interest to you. If you do find this useful, I’d appreciate knowing about it.

Thanks @Gglaspell , will try this out on the warehouse bag I have.

Not sure if this would be helpful to me, but this AI-based documentation generation is great and would definitely help out a lot of people starting out in ROS, and AI-agents in general.
