Image History in Google Earth/Maps
October 11, 2006 4 Comments
What happens to the imagery when Google (or Microsoft for that matter) updates their image database? Does Google allow people to access this data or does it disappear off into the digital wastebasket?

You can still access many previous releases of the map tiles in Google Maps if you know the parameters. Or see this site for a demo:
http://www.econym.demon.co.uk/googlemaps/examples/compare.htm?lat=44.559&lng=-123.2834&zoom=16&one=s10&two=s11
if that link isgets broken, then this might be better:

This site handles all the conversions for you
