Risks of hierarchical map displays Paul Wallich Mon, 20 Jul 2009 22:30:01 -0400

The other day, for no good reason, I got misplaced on some local dirt roads. "No problem," I thought, because my car had a GPS and a map database that actually knew about all those dirt roads. But when I zoomed the display out far enough to see where the nearest paved road back to exurbia might be, all the dirt roads disappeared, and I was apparently driving through a void. So I couldn't figure out which road would take me back to pavement, because I couldn't display both the roads I was on and the one I wanted to get to at the same time.
