Just a little more information on Google Earth (also available for free from Google if you type “Google Earth” in Google.com) and Google Maps satellite view (also free) maps.google.com – you can use street addresses any time – usually easiest done in 100 Main Street, 42276 or some similar fashion. It’s also very easy with lat/long coordinates in the search field. There is a ton of information for free there. Also consider http://virtualearth.msn.com for older but more complete satellite maps. – L.C.
