Here, the fake claim isn't the brand name, it's the product itself. He's selling a thing that looks exactly like a land survey, that's being used as if it's a land survey, but actually isn't. His measurements may be right (they probably aren't, this guy is mostly just scraping and reselling Google Maps, including literal screenshots from his browser, I sure hope he's paying the licensing fees to do that legally). But even if his measurements were per-millimeter accurate, it wouldn't change the problem. He's selling things that are intended to be used like land surveys, but aren't.

If I bought a printer, and I printed off some money, and it's a perfect reproduction (identical size, identical weight, identical materials, identical to any other dollar), is it a fake dollar? If I put on my website that these fake dollars are "not intended to replace real US currency", but don't actually mark that anywhere on the dollars themselves, am I good to go?
If I actually want to be in the "fake money" business ethically (say as a prop for plays and movies, or as a toy for kids), would it not be reasonable to require me to declare it as such? (Like fake money usually does, right on each bill? See https://propmoviemoney.com/collections/full-print-prop-money - 'Motion Picture Use Only' - as an example)
