A couple more howtos to try out:

For this second one, I've hit an out-of-memory error running the pipeline script on my chromebook.

I'd downloaded:
* 1m DSM model, bounded to 42km x 50km around Queenstown.
* This is 1.2 Gig
* Dimensions: 42,427 rows x 50,430 columns.
* Total Cells: ~2.14 billion cells.

Asking AI to work out how much this would cost on Cloud compute for all of New Zealand, it suggested $1000 to $2000 (with lots of caveats).
Also suggested a number of optimization strategies.
