Synthetic aperture radar image of Death Valley colored using polarimetry. Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation.
Cirrus are wispy clouds made of long strands of ice crystals that are described as feathery, [1] hair-like, or layered in appearance. [2] First defined scientifically by Luke Howard in an 1803 paper, [3] their name is derived from the Latin word cirrus, meaning 'curl' or 'fringe'. [4]
The following is a timeline for Google Street View, a technology implemented in Google Maps and Google Earth that provides ground-level interactive panoramas of cities. The service was first introduced in the United States on May 25, 2007, and initially covered only five cities: San Francisco, Las Vegas, Denver, Miami, and New York City.
High-resolution satellite imagery (1 metre and less) has been available since 1999, [3] [4] but its use for North Korean studies did not emerge until 2012. [1] By 2004, researchers and NGOs had imaging and computing capabilities comparable to those available to the US government 20-30 years earlier, in the 1970s.
Seasat [3] was the first Earth-orbiting satellite designed for remote sensing of the Earth's oceans and had on board one of the first spaceborne synthetic-aperture radar (SAR). ). The mission was designed to demonstrate the feasibility of global satellite monitoring of oceanographic phenomena and to help determine the requirements for an operational ocean remote sensing satellite sys
When an Earth observation satellite or a communications satellite is deployed for military or intelligence purposes, it is known as a spy satellite or reconnaissance satellite. Their uses include early missile warning, nuclear explosion detection, electronic reconnaissance, and optical or radar imaging surveillance.
The Iridium system was designed to be accessed by small handheld phones, the size of a cell phone. While "the weight of a typical cell phone in the early 1990s was 10.5 ounces" [6] (300 grams) Advertising Age wrote in mid 1999 that "when its phone debuted, weighing 1 pound (453 grams) and costing $3,000, it was viewed as both unwieldly and expensive."
