I have 2234 las datasets covering around 2000 km². I want to reduce the amount of tiles by 1/8 thus increasing the area per tiles by 64.

Which workflow could I use to merge neighbouring tiles without overlaps?

PointCloudCombiner is your friend here - if you can work out a nice way to assign new groups (perhaps based on the file names?) then you can use the PointCloudCombiner with the Group By set to your new Tile_name.

 

 

A good way with tiles is to try and map the filenames to a bounding box which can be helpful.

 

 

Another approach might be to read everything into a Tiler transformer, however, I would try and avoid that as I expect it could take a while to clip everything.

 

 

2DGridCreator, BoundingBoxAccumulator are both tools which you might find helpful

It does not have to be 8 -if it is easier mathematically 9 or 12 would also work.
