I could be wrong about this, but I don't think its illegal to take a picture of anyones property as long as they do not trespass into said property. What would be the difference between this and the town sending inspector to drive around in a vehicle like the one used to fix street lamps, If they use the vehicle from the street then they do not trespass. I also submit that they wouldn't even need to take a picture of the pool as long as the one who sees it has the proper authority, they would technically be a witness. People are just mad because they got caught, If you have an illegal pool then you gotta pay up. I also believe that any construction company that builds a pool without proper city permits is NOT to be trusted to build anything in your home.In some towns/cities/etc, the police/regulatory agency/etc are restricted to what's in view without the homeowner's conscent. So, say they walk past your house...you have an "illegal" pool in your backyard. If it's in "plain view" of the street....you're SOL. If you have a 6" fence blocking the view of said pool, the police/regulatary agency/etc is SOL because it'd be considered trespassing for them to enter the property without your permission. The same should apply to the use of Google Earth. You have no given Google concent to photograph your property, thus making the action an invasion of privacy. Which would prohibit the police/regulatory agency/etc from legally using Google Earth to further invade your privacy.
