Various mapping programs depending on the end Project. Skyline Mapping Software, Pix4D, and many others. One reason my post count is insane is I can get a project going and unless it really big project, just surf the web on the same computer. When we had a few monster projects this computer ran non stop for a week and was up to 210 Gig of RAM used, and the two video cards were hot, even with all the cooling fans screaming.
Most times, I just start a processing session, and let it churn, and surf over to Pelican. I have the task running on one monitor and Pelican on the other.
I regularly bump into the limits of file size with Photoshop and tif files. The mapping software will churn out monsters, and there is no easy way tweak the color balance or brightness.
This was a small part of one project.
