Wow the list would be long. Here are a few that come to mind:
Pan down and rotate so I am looking south to find "north faces" for elk hunting.
Finding hidden water sources (green patches).
Green vegetation in arid areas.
Using the history of photos to look at the age of a burn, clear cut etc (example, photos from 2013 show no burn but there is one today, so around 3 years old).
Using the history of photos to look at a water source to see which hold water on the driest years (using that to find the most dependable water sources for my son's upcoming antelope hunt).
Finding the best used roads to access the area I am going.
Discovering glassing points. Go "stand" on that spot and see what can be seen.
Finding micro pockets that cant be seen or glassed from the road.
