Here are only the processing time estimates.

• About one week to develop 360.000+ images from raw to tif.
• About one week to merge and upscale images to about 14.000 180MP super resolution images.
• About one week to render the final panorama.
• About 3 days to convert from one huge image to tiles which could be publish to webserver.

Some of this processing was done several times to get best results.
Before the processing could start, the images needed to be prepared. Correcting colors, haze removal and preparing for stiching took most time (weeks/months).
