The satellite images have pixel ground resolutions of under 0.5 meters, and overlapping images from different angles can be used to extract elevation data for DEMs. Based only on satellite position, there may be errors of several meters, but through ground control registration these can be reduced to point-to-point errors of 20 centimeters or ...
But on Oct. 10, the U.S. Geological Survey's Landsat 8 satellite, which NASA helped to develop, managed to capture an image of the phenomenon, which is actually fog caused by rising steam.
Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.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.
