Google Earth is a virtual globe, map, and geographical information app. With Google Earth online or Google Earth for mobile, you can travel around the planet, exploring 2D or 3D recreations of maps, terrain, 3D buildings, and much more. You can see the planet from space using satellite imagery or view the world at ground level with the integrated Google Earth Street View feature. The mobile version also allows you to explore on your own or use the "tour guide" to bring up virtual tours from around the globe.
Google Earth may be the most advanced, feature-rich app for viewing satellite imagery, maps, terrain, 3D buildings, faraway galaxies, and the deep ocean. But it's not the only one. Here are three competitors that can also get the job done.
NASA World Wind is a free desktop app, developed by NASA with the open-source community. It allows you to zoom from satellite altitude to anywhere on Earth. Leveraging Landsat satellite imagery and Shuttle Radar Topography Mission data, the app enables you to experience earthly terrain in 3D. NASA World Wind users can also view, tilt, rotate, and zoom the Moon, Venus, Mars, Jupiter, and the Galilean Moons. There are also numerous plug-ins and add-ons for features like camera-controlling scripts and XML files that can display place-markers as icons.
The mobile-only app provides 2D and 3D views of the sky, easing identification of planets and constellations. Spin the Earth or the planet of your choice with one finger. It also shows times when planets are most visible.
Explore the world with Marble's robust set of city and street-level maps. Search for addresses and places of interest. Figure out and create walking, biking, and driving routes online and offline via drag and drop. View clouds and sun shadow, follow satellites and space stations, and display their orbits in real-time. Time travel using maps from past centuries. Use the app similarly to a desktop globe, and pan around and measure distances. At closer scale it becomes a world atlas, while OpenStreetMap takes you to street level. Marble also offers maps of the moon and other planets.
