[pdal] tindex creating empty geometry column. Index creation makes an index, but PDAL: readers.tindex: Unexpected argument 'merge'.

[Adam Steer]

Interesting. This conflicts with an earlier suggestion from Howard [1], which worked - and most importantly fit into the PDAL pipeline workflow.

I’ve got a PDAL 1.3 instance lurking around, I’ll do some testing with that,  since that’s where the pipeline approach last worked.

My testing in the last few days has been in the dockerised PDAL 1.4 on MacOS, and PDAL built from source on CentOS, pulled about two weeks ago.

Thanks again
