Actually it is public records. Many County Recorders and Assessors have to gone to satellite photos and GPS coordinates for property locations. Even the county I live in, Yavapai County, in outback Arizona. I can locate any property within the County, with a map to the address and a satellite image that is updated every two years, over the internet at the County Web Site. It is already public information on where you live, how much the property taxes are, etc. It would be easy to link to an MLS for a picture of you house. I suspect the Assessors use it to see if you have made any major additions to the property without reporting it. Too late to be concerned, it has been in use for many years. Here since 2000.
KCJ, it's how I find my way home every night.
