Bing Maps, 3D interface runs inside Internet Explorer and Firefox, and uses NASA Blue Marble: Next Generation. Bhuvan is an India-specific virtual globe. Earth3D, a program that visualizes the Earth in a real-time 3D view. It uses data from NASA, USGS, the CIA and the city of Osnabrück. Earth3D is free software .
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.
Earth3D was developed as part of a diploma thesis of Dominique Andre Gunia at Braunschweig University of Technology [1] to display a virtual globe of the earth. It was developed before Google bought Keyhole, Inc and changed their product into Google Earth. Earth3D downloads its data (satellite imagery and height data) from a server while the ...
The Earth mode has a default data set with near global coverage and resolution down to sub-meter in high-population centers. Unlike most Earth viewers, WorldWide Telescope supports many different map projections including Mercator, Equirectangular and Tessellated Octahedral Adaptive Subdivision Transform (TOAST).
Zooming in on a portion of the Euclid telescope's map 600 times reveals the galaxies within the cluster Abell 3381, located 470 million light-years away from Earth.
Other features include the ability to copy the current view onto the clipboard, where it can by displayed by pasting it on an image program such as Microsoft Paint, thematic maps, charts, and clocks that all allow the user to customize the area, an "Earth shadow" feature which creates a shadow on the Earth if on 3D, and a 2D feature that allows ...
For example, a 1-meter diameter optical telescope is two million times bigger than the wavelength of light observed giving it a resolution of roughly 0.3 arc seconds, whereas a radio telescope "dish" many times that size may, depending on the wavelength observed, only be able to resolve an object the size of the full moon (30 minutes of arc).
