When third parties started riffing on Google Maps — whether through hacks or by posting screenshots of its satellite images — I wondered what Google thought about it. After all, the satellite photos are watermarked with copyright notices. I suspect they’re okay with it, though, since the official Google Blog linked to a whole mess of them last Friday. How about that? Google isn’t Sony. But I think we already knew that.

Anyway, here are a couple more hacks of Google Maps. Here’s one that shows New York subway stops (via — and requested by — Kottke). Or, how about a program that lets you view Google Maps on your Tivo (via Gizmodo)?
