How often does satellite picture on google earth gets refreshed?
It depends, some areas like war zones, for obvious reasons. Other places that are updated more frequently are popular tourist destinations and larger cities, Seattle will be updated more frequently than say Alma ,Ga. Google earth also points to a hidden feature allowing you to bring up the current view in Google maps,if you choose the “link to this page” option in Google maps after searching for a location, you can bring up the current view in Google earth by appending “&output=kml” to the URL. No one answered you sooner because you put this question in education, instead of Google.
