Thank you for all the suggestions guys. I'm Located in Luling, TX. It's more of a rural area so I know there may not be as many data points to work with but all the help is appreciated. I'm just curious, how often is satellite photography taken? I found google earth has them skipping every few years then 2 in one year as far back as 2011, 2006,2005,2002 then 1995, does that sound right?
