Its an amazing image, the product of much effort. Most of the glitches cited are unavoidable due to moving traffic between shots. However, the one cited below is more problematic -

As i'm unfamiliar with the Autopano Giga 3.0 software, was this due to relying upon a fully automated workflow with sparse manual curation? That said, 3 months on a single workstation (albeit with 32-cores and 256 GB RAM) seems a bit self-limiting. I noticed that the Autopano software is available on Linux - and 1000-core HPC clusters are fairly common these days in large firms or companies that provide leased CPU time (without even mentioning Cloud services which might have memory restrictions). In either case, a 31x-speedup in processing (down to 3-4 days vs 3 months) could be achieved. However, Fedex'ing the data on a hard-drive would only add 2 days to the schedule - an ample margin to enable more curation of borders.

N.B. my non-image (genomics) work typically involves using 100-600 nodes of 1k core HPC.

Darn it --- if I was a resident of the UK I could have been a contender:

I think they really overprocessed the zoomed-out version of the images. Here's a comparison between the two. The top image is what you see when you zoom all the way in, and you still see that image when you zoom back out a little. From that zoom level I scrolled out one more click with my scroll wheel to get the bottom image. The photos aren't aligned right so it also changes position slightly. That's not so bad, but really I don't like the sudden change in appearance.

They processed it to remove the dullness of the image and add more color, but it also looks like they oversharpended it.
