We collect imagery from national park webcams in the Great Smokies and Mammoth Cave parks and then make animated gifs of those webcam images. In 2011, I penciled this quick note:
110629 Nice time-lapse photography for all cameras and satellite. Make movie?
Beginning in 2012, we started archiving these animations.
New webcam added to animation archive
Turns out, we had Mammoth Cave working for the entire 2021 year, but didn’t have them accessible via a web page. With a little grep and sed action, the gifs were added to the default page for the Great Smokies archive. Visit the interface here.
We plan on having at least the last year covered in the archive. At 60 GB a year now with HD cameras, it can get expensive hosting multiple years. I do have the years back to 2012 stored offline.
