DigitalGlobe is an American commercial vendor of space imagery and geospatial content, and operator of civilian remote sensing spacecraft. The company went public on the New York Stock Exchange on 14 May 2009, selling 14.7 million shares at US$19.00 each to raise US$279 million in capital. On 5 October 2017, Maxar Technologies completed its acquisition of DigitalGlobe. The company's "WorldView" satellites should not be confused with the unrelated WorldView company (a stratospheric balloon operator). Origins WorldView Imaging Corporation was founded in January 1992 in Oakland, California in anticipation of the 1992 Land Remote Sensing Policy Act (enacted in October 1992) which permitted private companies to enter the satellite imaging business. Its founder was Dr Walter Scott, who was joined by co-founder and CEO Doug Gerull in late 1992. In 1993, the company received the first high resolution commercial remote sensing satellite license issued under the 1992 Act. The company ...

Satellite Imagery
Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world. Satellite imaging companies sell images by licensing them to governments and businesses such as Apple Maps and Google Maps. History The first images from space were taken on Sub-orbital spaceflight, sub-orbital flights. The U.S-launched V-2 flight on October 24, 1946, took one image every 1.5 seconds. With an Apsis, apogee of 65 miles (105 km), these photos were from five times higher than the previous record, the 13.7 miles (22 km) by the Explorer II balloon mission in 1935. The first satellite (orbital) photographs of Earth were made on August 14, 1959, by the U.S. Explorer 6. The first satellite photographs of the Moon might have been made on October 6, 1959, by the Soviet satellite Luna 3, on a mission to photograph the far side of the Moon. The Blue Marble ...

GlobeXplorer
GlobeXplorer was an online spatial data company that compiled and distributed aerial photos, satellite imagery, and map data from their online spatial archives. GlobeXplorer has been credited as the first company to establish a business around compiling and distributing online aerial and satellite imagery. In 2007, the company was acquired by DigitalGlobe. GlobeXplorer's imagery and property data was licensed to many online information websites. GlobeXplorer obtained its content through online distribution relationships with about 30 of the world's top acquirers of aerial, satellite, and property data. GlobeXplorer's primary products were the ImageAtlas viewer and ImageBuilder web developer toolkit. It also provided ImageConnect extensions and web services for GIS and Computer-aided design. GlobeXplorer's defensible core competence was its ability to meter custom profiles of content for consumers and pay royalties to providers based on 512x512 "standard image units" (SIU). This ...

Panchromatic
Panchromatic emulsion is a type of black-and-white photographic emulsion that is sensitive to all wavelengths of visible light. Description A panchromatic emulsion renders a realistic reproduction of a scene as it appears to the human eye, although with no colors. Almost all modern photographic film is panchromatic. Some older types of film were orthochromatic and were not sensitive to certain wavelengths of light. As naturally prepared, a silver halide photographic emulsion is much more sensitive to blue and UV light than to green and red wavelengths. The German chemist Hermann W. Vogel found out how to extend the sensitivity into the green, and later the orange, by adding sensitising dyes to the emulsion. By the addition of erythrosine the emulsion could be made orthochromatic while some cyanine derivatives confer sensitivity to the whole visible spectrum making it panchromatic. However, his technique was not extended to achieve a fully panchromatic film until the early 190 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Start-1
Start-1 is a Russian satellite launch vehicle based on the RT-2PM Topol, a Soviet Union, Soviet intercontinental ballistic missile developed by Moscow Institute of Thermal Technology. History The Start-1 launch vehicle derives its name from the START I, Strategic Arms Reduction Treaty (START I) between the United States and the Soviet Union. The START I treaty called for both sides to limit their nuclear arsenals to 6,000 nuclear warheads atop a total of 1,600 ICBMs, Submarine-launched ballistic missile, SLBMs, and bombers. This led to a lot of surplus ICBMs on both sides, including the Soviet Topol. After the collapse of the Soviet Union, Russia took over responsibility for executing the treaty. The Russian government decided to dispose of some of their ICBMs by using them as launch vehicles, which was an allowed method of disposal under the treaty. Modification of the ICBMs into launch vehicles was carried out by the Moscow Institute of Thermal Technology (MITT), which ...

Svobodny Cosmodrome
Svobodny (russian: Свобо́дный) was a Russian rocket launch site located approximately 15 km north of Svobodny, Amur Oblast. The cosmodrome was originally constructed as a launch site for intercontinental ballistic missiles called ''Svobodny-18''. It was initially selected as a replacement for Baikonur Cosmodrome in the Kazakh Soviet Socialist Republic, which became independent as Kazakhstan after the dissolution of the Soviet Union. However the development of Svobodny was subsequently ended in 2007 in favour of a totally new space port, the Vostochny Cosmodrome. The breakup of the Soviet Union left the primary cosmodrome, to be used by the successor state Russia, at Baikonur in a foreign country, Kazakhstan. An arrangement to rent the facilities for $115 million annually was arranged. Launches were moved to other facilities, like Plesetsk Cosmodrome, but this location is too far north to be useful for many launches. Studies for a far-east location closer to the lat ...

Terabytes
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as The Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
