I have no idea how the technology works, but the images are from varying dates, and are all linked together. Some areas are green (spring or summer) and then right next door, you will see snow on the ground. That aside, it is an awesome tool for exploring new areas. I wish I would have had this tool when we were first looking for some hunting ground.
As for updates, it shows our duck club before we expanded the wooded wetland area, so I would say that image is about two years old. Terra Servers most recent image is the early 90s.
I probably spent about two hours flying around this weekend. When I showed my two hunting partners, they were like the "orgasm guy" on Saturday Night Live :laughing:
