These are images that are taken using satellites that offer a view from the sky that would appear to be like that of a bird. You can view such images on various sites.
With satellite imagery, one can see images of photographs of any place on Earth. Satellite imagery is more detailed and clearer than Infrared images.
For past years earth-based satellite imagery in Google Earth you can select 'Historical Imagery' under View menu. This shows a timeline slider from which to select available satellite and aerial imagery from the past. NASA also provides vast archives of satellite imagery much of which are available online such as the NASA Image Gallery
Google Maps provides satellite and map views in addition to Street Views. The satellite view of Google Maps uses the same backend satellite imagery database used by Google Earth.The satellite imagery are typically from the GeoEye or DigitalGlobe owned satellites, and some of the imagery are actually aerial photos from aircraft using special high resolution cameras.
Google Earth's imagery comes from a variety of sources such as aerial photos and commercial satellite imagery. Some of the imagery even comes from kites and air balloons. Google buys or licenses the use of this imagery. Some of the imagery is given to Google by city or state governments. The primary sources for Google's satellite imagery comes from GeoEye and DigitalGlobe.
NASA provides vast archives of satellite imagery much of which are available online such as the NASA Image Gallery.Google Maps is a great tool to see satellite imagery of earth. Remember to change "Map" view to "Satellite" to display the satellite imagery.If you need better (higher resolution) imagery, you could try other mapping programs or, if you have the resources, you could consider purchasing imagery for your own use.Here are a few companies with websites to start with, but there are others, try doing an internet search for satellite and aerial imagery:DigitalGlobeSpot ImageMapMartTerrametricsTerraServer
Yes that is the primary disadvantage of visible satellite imagery.
Actually its not the altitude of the satellite but the resolution of the camera that is responsible for a high resolution imagery. In fact the better resolution imagery in Google Earth comes from aerial and street-level photography.

Google Maps and Google Earth are great tools to see satellite imagery of earth. In Google Maps remember to change "Map" view to "Satellite" to display the satellite imagery. Google gets its imagery from a number of commercial imagery providers including: DigitalGlobe and GeoEye, which operate a constellation of high-resolution Earth-imaging satellites, mapping aircraft and an international network of ground stations.

For past years earth-based satellite imagery in Google Earth you can select 'Historical Imagery' under View menu. This shows a timeline slider from which to select available satellite and aerial imagery from the past. For example, if you're in London then you can jump to 1945 to see WWII imagery.
