Digital Earth is a virtual representation of the planet, an information system with tremendous amount of multi-resolution and multi-scale data as shown in multiple dimensions. By acquiring the large amount of data of the Earth, and utilizing the techniques of computer, image and graphic processing, network, virtual reality and so on to study the real earth and its relevant phenomena in digital ...

constructed upon a height (by footing) or breaking in to the ground, in a building, making a close relation between earth and soil is of great importance. in addition, earth as a prior factor in creation of a shade and residence, plays a crucial role in architecture history. throughout the different area, earth is paid attention differently: as a source of cool (in china), a source of heat (cap...

A satellite communications system is based on antennas in a stable orbit above the earth. Satellites serve as relay stations in the sky. The basic idea of satellite communications is that two stations on earth discuss via one or more satellites. So a little bit of satellite-related terminology: 1. Earth station is an antenna on or near the surface of the earth. 2. Uplink is a transmission from ...

Minimum-mass tether designs are developed for a spinning human transport that not only provides artificial gravity, but also the potential for free-return aborts. The investigation reveals that severing the tether can provide a propellant-free boost to return astronauts to Earth in the event of an aborted landing on Mars. Earth–Mars–Earth, Earth–Mars–Venus–Earth, and Earth–Venus–Mars–Earth traj...
