Someone showed me an alternative to http://maps.google.com/ - this allows you to see very detailed aerial maps and of course is linked to Google earth.
http://maps.live.com/ - a Microsoft run version of Google maps. Very similar, but with one major difference that you can see views of certain areas from different angles. (North, South, East or West) This is all achieved from with the Internet browser.
Check it out - (Anthony this one is for you)
