How does Google Earth differ from clicking the Satellite button on Google Maps?
[/QUOTE]
The main benefit I find over Google Maps is that Earth can display train/subway lines on the map. Immensely useful when I am trying to contact somebody for work and they’re somewhere in NoVA. Type in the address, and a quick glance will tell me if it’s within a reasonable walking distance of a Metro station.
It’s also a lot more flexible in displaying driving directions. Being able to quickly zoom in and out of specific parts of a path that seem unusual (and if DC beltway onramps and offramps are anything, they’re unusual), skipping over long sections of straight road, easily map gas stations or restaurants or parking garages over a travel route, all easy in Earth.
I’ve also been able to look through the layout of golf courses before putting down good money to play there, as well as just finding new courses that don’t advertise much.
