I'm constantly surprised at what Google is doing. If you haven't tried Google Earth, do, especially now that it has Google Sky. Meanwhile, Google Maps continues to increase coverage: Topsham now has high-res throughout. I see also from Google Blogoscoped that Google has begun, for some US locations, to add a Street View option where you can view locations from ground level (more systematically than the Ordnance Survey Geograph project - which is excellent but very much dependent on where the volunteer contributors felt was photogenic; see its Topsham coverage).
The idea of a ground level photographic map isnn't new: Blogoscoped has an interesting post, Photo-Auto Maps (1907), about a century-old Rand McNally travel guide with images to help drivers recognise important turns. The quoted poster, however, makes a slightly strange assumption that this idea was down to conventional road maps not having yet been developed. Road maps actually long pre-date cars. A few lovely examples: Paterson's British Itinerary, 1785, probably the first pocket-sized road map and gazetteer; the Gough Map, 1306, the oldest surviving road map specifically of Great Britain; and Peutinger's Tabula, aka Tabula Peutingeriana, a 12th century copy of a 4th century road map of the Roman Empire.
Here, at the University of Applied Sciences, Augsburg, is a full scan of the Peutinger map - and here's the British section. In the latter, there are signs of topographical and linguistic garbling: Dorchester isn't east of Southampton. You can identify the locations via the placename index at Thomas G. Ikins' Roman Map of Britain site. - Ray
