Google Earth is a vast program, it uses satellite imagery from different sources, like the Landsat program, which is a collaboration between the US Geological Survey and NASA.

Furthermore, Google Earth also obtains geological and topographic data from different sources, in order to fabricate a far more accurate and complete representation of the earth’s surface.

Users can easily explore the world by just entering the addresses and coordinates. In fact, in 2019, Google disclosed that Google Earth covers about 97 percent of the globe, which didn’t sit right with many countries.

Fun fact, Google Earth has been viewed as danger to privacy and national security, which led to it being banned in a number of countries. Moreover, several countries has also demanded to leave certain areas obscured in the satellite images, those areas are usually military facilities.

How Old Are Google Earth Images?

Google Earth displays the the planet by using a single image from a distance, however, after you zoom in the imagery turns into an imagery of the specific area, but with much finer details, that can also change in time and date.

Nevertheless, how old are those images? Well the Google Earth images can be anywhere from 1 to 3 years old.

Now, Google Earth obtains its imagery from either satellites or aircraft, although before the launch of NASA and the satellite called USGS’sLandsat 8, Google was relying on the imagery from Landsat 7, which went through a hardware malfunction, that resulted in diagonal gaps in the images.

Furthermore, if you want to check the age of an image, here’re few methods you can try:

  • “Historical Imagery” feature: In order to use this feature, all you have to do is right-click on the location in question and choose ‘Historical Imagery’ from the menu, which will open a timeline on the top of the screen, that will show the available images for the specific location. You will then slide the timeline to right and left as to see the different available images, as for the date, you’ll see the them displayed on the bottom of the screen.
  • Check metadata: Another method that you can use to check how old an image is by checking the metadata for the image. You merely have to right-click on the location and click on “Properties” from the menu, where you will see the information about the image, which will include the date of the image that it was captured on.

With the help of these methods, you will get to know when an image was captured and whether there are any newer images available or not. Although, you should keep in mind that the availability of those historical imagery as well as all the other sources of information can change depending on the location and where the image is sourced from.

Google Earth retains its data from several sources, and the images can change depending on two factors: location and the source of the imagery. While some imagery may be of high quality and newer, others may be outdated and may even be of low quality.

Google Earth is using a number of sources for its imagery and maps which include satellite imagery, aerial photography, and user-generated content.

  • Find a location.
  • Click ‘View Historical Imagery’ or, above the 3D viewer, click Time.

FAQs

What Is Google Earth?

Google Earth is a software that allows you to explore as well as interact with a virtual globe and a detailed map of the Earth. It was developed by Google and is available on all the devices including Android and iOS.

Moreover, Google Earth was developed in 2001, but has been evolved with time, now it uses a bunch of sources for its data. For instance, it uses satellite imagery and aerial photography for a far more detailed images.

Why Are Some Images in Google Earth More Up-to-date As Compared To Others?

The quality of the imagery on Google Earth depends on the location and the source of the imagery, for instance if the image is obtained from the satellite and is captured years ago, it may not be of high resolution.

However, as for the newer images, they may be of high resolution as Google Earth now uses different and more developed sources.

You can see how old an image is by using ‘Historical Imagery” feature or by checking the metadata.

Can You Travel Back In Time On Google Earth?

Yes, you can travel back more than forty years on Google Earth. You merely have to open Google Earth and enter the location in the search bar that you can find on the left panel.

You will then be taken to the location, as you get there, find the Clock icon that reads ‘Historical Imagery’, which will take you back in time.
