Bill, I truly do value your input. This started as a project just for me and I was just wondering how it might help others if I shared it. One thing you may not know is that on Google Earth there is a tool that you can use to change the dates of the satellite passes over any site. In most cases I can get 2012 as the OLDEST pass so any view I have is at the oldest 2012 and most are up to date as of 2013. I was surprised to see some places I was researching had vehicles in the same place and appeared to be the same vehicles for 8 years. As a side note, I was an imagery expert for the Air Force Special Operations for several years so I can "read" the imagery better than most. It comes in handy!
Again thanx
