The Wisconsin guys may want to check their areas. My property in northern Barron and a buddy's spot in western Sawyer county both have new imagery dated 9/28/15.
Just checked the area where my cabin is and it is still an image taken from before we purchased the property. Can't wait for them to update that so I can see all our new openings and trails we put in. That's in NE wi. My lease in SW wi was updated in late summer.
On Google Earth it should be located in a data strip near the bottom of the satellite image itself. It should also give you the geographic coordinates as well.
Also, for anyone unaware, in the toolbar at the top of the page should include something that looks like a clock or a stopwatch. If you click that and then slide the bar you should be able to go back and view historical imagery. Pretty cool stuf, as you can somewhat watch the progression of things. In my area this ranges from April of 1999 through June of 2015, probably about 8 images total. Very neat in my opinion.
