Just so the rest of the world does not freak out when they look at accuracy compared to Google:
Depending on just where you are, Google Maps / Google Earth can be more or less accurate. It’s not at all uncommon to find horizontal errors > 20 feet. I have seen this with multiple locations that were surveyed to “couple centimeter" accuracy. We’ve been into the details of why. You can dig into the archives for all the details.
