The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and coordinates, or by using a keyboard or mouse.

- More about image types & their collection dates
You can see a large collection of imagery in Google Earth, including satellite, aerial, 3D, and Street View images. Images are collected over time from providers and platforms. Images aren't in real time, so you won't see live changes.
• Some images list a single acquisition date, which is defined by the image provider.
• If an image is a mosaic of multiple satellite or aerial photos taken over days or months, a date range with a start date and an end date is displayed to show the dates the images were collected between.
• If little or no date information is supplied by the data provider, a start and end date are shown for the range within which we can be reasonably certain the image was taken.
Examples:
• "Summer 1995" might become start:1995-06-01 and end:1995-09-30
• "1943" might become start:1943-01-01 and end:1943-12-31
• Images closer to the ground are usually made up of one image. The date displayed in these cases should stay the same wherever you move your cursor.
• Aerial images are usually made up of a mosaic of several images. The date may change as you move your cursor around the map.
Satellite & aerial images
The satellite and aerial images in Google Earth are taken by cameras on satellites and aircraft, which collect each image at a specific date and time.Those images can be used in Google Earth as a single image with the specific collection date, but sometimes:
• The images are combined into a mosaic of images taken over multiple days or months. These images are displayed as one seamless image and the date may change as you move your cursor around the map.
• There is limited information about the image collection and the date displayed reflects the start of a date range when the image was most likely collected.
• When the "3D Buildings" layer is turned on, the detailed terrain and buildings images are derived from aerial images collected over multiple dates, so Google Earth does not display a collection date.
• The collection date information is lost or inaccurate due to human error or other issues.
Apr 15, 2021 · Thanks to the close collaboration between Google Earth, ESA, the European Commission, NASA and the US Geological Survey, 24 million satellite photos from the past 37 years have been embedded into a new layer of Google Earth – creating a new, explorable view of time on our planet.
