Google Maps has updated their aerial imagery for Polk and Warren counties.
I believe both counties are now hi-res, which means you can go to the full zoom level of Google Maps and get some nice detail.
The Polk images look fairly new to me, and are much better than the previous ones, in my opinion. I don't like the color of Big Creek's, but the high-res is nice. Nobody home at Walnut. 1 car at Big Creek, and the players' shadows might be approaching basket #12. The Ewing images are awesome, as are Grandview. Who has the bigass bright yellow van at Ewing?
Warren is now in hi-res, but I'm not sure the images are new. Doesn't Pickard have tee pads? None visible on the images. I swear some online service (probably Warren County GIS) had tee pads visible there at one point, but not on Google Maps.
