It captures images with high quality and more frequency than Landsat 7. It is an earth imaging satellite launched in 2013 and still in operation. The satellite that Google Earth uses is called the Landsat 8. But today’s aerial photos are taken using aircraft flying at altitudes of over 10 kilometers (6 miles). The first aerial photographs were taken in the late 1858s by Gaspar Felix Tournachon, also known as “Nadar”. Images are taken using cameras mounted on satellites and aircrafts.Īerial photography is an ancient technique that has been used for centuries to document landscapes and map out territories. There are many sources for this information, but most of the data is generated from aerial photography of the earth’s surface. Google Earth Pro constantly adds new images, so the archive keeps growing and getting more detailed as more pictures are taken each year. The tool will take you back in history, so you can see how your neighborhood, city, or country has changed over time. Google has been preserving old satellite images of Earth in its archives and you can find them with their “ Show Historical Imagery” tool. This is especially true for places that have undergone dramatic changes over time.įrom Google Earth version 5.0, they introduce Historical Images, which allows users to view old images. Old pictures of places are a great way to remember the past. Google Earth uses Digital Elevation Model Data from NASA’s Shuttle Radar Topography Mission. The highest image resolution in Google Earth ranges from 15 meters to 15 centimeters. What Is The Highest Resolution In Google Earth? But this theory was disproved when Google Earth presented what is known as “Google Earth Pro” which had crisper images than its predecessor. It was speculated that Google Earth was using a low-resolution, older version of its maps. The reason for the low quality satellite images is due to the compression algorithm used in Google Earth which reduces file size by shrinking the pixels in order to reduce bandwidth costs.
