- Here's a citation from Mark Aubin's post at the Google Librarian Central, about the source of Google Images:
"We collect it via airplane and satellite, but also just about any way you can imagine getting a camera above the Earth's surface: hot air balloons, model airplanes - even kites."
Please see the whole post at the related link from Google.
- And, for extra credit, see the blog post about "How Google Earth (Really) Works" by a co-founder of Keyhole, who first built what became Google Earth.
Google Earth acquires their images from many sources. Some of these sources include from satellites in space, airplanes flying over particular locations, and people that drive along the street, taking pictures and video of the area.

The images in Google Earth (and Google Maps) are updated on a continuous basis. It's hard to say exactly when an area will be updated because some areas may be updated mor…e frequently than others (just because that data is more readily available). While most images are no more than 3 years old in high resolution areas, low resolution imagery in some areas may be older. When high-res or newer imagery is not available, the base map used in Google Earth is a circa 2000 TerraMetrics/NASA 15 meter resolution base imagery. It takes months of post processing new imagery before they go online so bulk updates usually happen about every 2-3 weeks. Google Earth and Google Maps share the same backend satellite image database and are updated together. Why are newer images sometimes found in Historical Imagery? Newer imagery is sometimes available in 'Historical Imagery', which can be enabled from the View menu option in Google Earth. Sometimes older images are actually of better quality than new images (i.e. there might be a huge cloud over a certain area which encourages using the older, clearer image). This feature is not available in Google Maps. Where was Google Earth imagery last updated? If you want to see where Google Earth (and Google Maps) imagery was last updated either check out the Google Earth Blog for update announcements or simply click on the 'Google Earth Imagery Updates' link below to see the highlighted areas on the globe. When will my area be updated? Due to overwhelming demand when a given area will be updated Google has created a new e-mail notification service. Check out 'Follow Your World' in related links below.
Some are satellite and others are aerial (taken from airplanes with special high resolution cameras and also from air balloons). Street View photos, however, are taken from …car, van, or bicycle.
You can't update these yourself, but they are updated by Google every 1-3 years. You can, however, add your own content (placemarks, image overays, etc.) to Google Earth or …find other user-content in KML or KMZ files.
hi go to file email email image add your email address and check your inbox bye ALI KH (FROM IRAN)
The images are new now by new satellite views the images are clearer than before it was from 2003 now the images are from year 2005 that mean UPDATED
No body can get this serves
by satellite and other things like planes and things that can go above the ground
This seems to be the best answer I have found. The guy works for the Centre of Geographic Sciences so he should know what he is talking about. See related links for examples….
In Google Earth select Add > Image Overla yin the menu then select an image file to overlay onto the ground. You can set the transparency level and position the image on t…hemap. If, however, you want to add geo-tagged photos that becomepublically displayed in Google Earth and Google Maps then you canpublish them to the Panoramio web site. You can request that it bepublished to Google Photo layer. For details check out thePanoramio Frequently Asked Questions (FAQ).
Google updates its imagery every 2-3 weeks. You can see what has been updated in each imagery update in the related links below.
Google Earth provides a 3-D effect with 3-D buildings and tree as overlays on top of the base imagery. Also with terrain enabled in Google Earth, the satellite imagery conform…s to the topology so mountains (e.g. Mt Everest, etc.) appear in 3-D. For stereo 3-D views for Google Earth (i.e., 3-D glasses) see related reference link below.
They collect their satellite images from a variety of cameras including; low level satellite photography, aerial photography and even on occassion kite and balloon cameras. Th…ough most people think that the images are live they are in fact three years old on average.

Google Earth was first released in 2005 so 1998 imagery is rare. This means Google acquired and processed imagery from that year -- old imagery would be for a small area or… region. For example, there is imagery for 1938 in San Francisco, CA but for only within the city limits and New York City has some imagery for April 1997.
If you enable the ' Status Bar ' option under View menu then imagery dates (if available) will appear in status bar that shows at bottom of the map window in Google Earth. …Dates are approximate. Sometimes dates are when the imagery was processed as opposed to when it was captured so you could have an image with snow on the ground with a date in July. For more details on dates in Google Earth imagery see related link below to article.
Images of Google Earth are updated by people going out and taking more photographs of the planet. By taking regular photos, this keeps Google Earth up-to-date.

There are multiple ways to print the current view from GoogleEarth. The built-in way is pressing the print short-cut (e.g.Ctrl-P on Windows) or select Print option in File men…u. This willprint the map panel only. If if want to print the sidebar and wholeGoogle Earth display you need to take a screen capture of thescreen and paste the image from the clipboard into an applicationto print it.
