my 14 year old question on SO was deleted finally, 33K views

I think I asked a handful of questions ever, and this one was never answered very helpfully I just learned it eventually through practice

Helluva list ... so happy to find it

Found my old reading list, it extremely interesting and helpful to me. Wish I'd maintained it ... but restoring this into a partial list is going to help, a bit

Was actively keeping it 1997-2000, and there's helpful notes of earlier years and some of what was going on (where I was etc)

Fuck yeah, it's sunny and I can read and listen to Urge Overkill a little longer

still using buildvrt? no need (since GDAL 3.11), template in your sources as a comma-separated list and then this json description can be opened by any GDAL-enabled tool

not so bad across the suite of 3 (the palletized version only takes the last layer it seems) - I intend to make a bucket with this mean(, na.rm) version is that of interest?
July 26, 2025 at 10:31 PM
or, a more permanent problem now? I see better coverage with the mean of the netcdf layers (second image)

Oh nice! Thanks for the pointer

Yml this paper, was referenced in old maptools for geog direction which I used elsewhere too

Sorry for image, I can't copy the link 🫠

this is a much much better image from longer ago, this is the game to catch the windows together
