WorldView-1
WorldView-1 (WV 1) is a commercial Earth observation satellite owned by DigitalGlobe. WorldView-1 was launched on 18 September 2007, followed later by the WorldView-2 in 2009. First imagery from ''WorldView-1'' was available in October 2007, prior to the six-year anniversary of the launch of '' QuickBird'', DigitalGlobe's previous satellite. WorldView-1 was partially financed through an agreement with the National Geospatial-Intelligence Agency (NGA). Some of the imagery captured by WorldView-1 for the NGA is not available to the general public. However, WorldView-1 freed capacity on DigitalGlobe's ''QuickBird'' satellite to meet the growing commercial demand for multi-spectral geospatial imagery. Design Ball Aerospace built the WorldView-1 satellite bus and camera using an off-axis camera design identical to Quickbird, with the instrument's focal plane being supplied by ITT Exelis. The camera is a panchromatic imaging system featuring half-meter resolution imagery. With an aver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DigitalGlobe
DigitalGlobe was 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 compa ...

GeoEye-1
''GeoEye-1'' is a high-resolution Earth observation satellite owned by Maxar Technologies (formerly DigitalGlobe), launched in September 2008. The satellite was acquired in the 2013 purchase of GeoEye. History On 1 December 2004, General Dynamics C4 Systems announced it had been awarded a contract worth approximately to build the ''OrbView-5'' satellite. Its sensor is designed by the ITT Exelis. The satellite, now known as ''GeoEye-1'', was originally scheduled for launch in April 2008 but lost its 30-day launch slot to a U.S. government mission which had itself been delayed. It was rescheduled for launch 22 August 2008 from Vandenberg Air Force Base aboard a Delta II launch vehicle. The launch was postponed to 4 September 2008, due to unavailability of the Big Crow telemetry-relay aircraft. It was delayed again to 6 September because Hurricane Hanna interfered with its launch crews. The launch took place successfully on 6 September 2008 at 18:50:57 UTC. The ''GeoEye ...

Geospatial
Geographic data and information is defined in the ISO/TC 211 series of standards as data and information having an implicit or explicit association with a location relative to Earth (a geographic location or geographic position). It is also called geospatial data and information, georeferenced data and information, as well as geodata and geoinformation. Location information (known by the many names mentioned here) is stored in a geographic information system (GIS). There are also many different types of geodata, including vector graphics, vector files, raster graphics, raster files, geographic databases, web files, and multi-temporal data. Spatial data or spatial information is broader class of data whose geometry is relevant but it is not necessarily georeferenced, such as in computer-aided design (CAD), see geometric modeling. Fields of study Geographic data and information are the subject of a number of overlapping fields of study, mainly: * Geocomputation * Geographic info ...

2007 In Spaceflight
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has symbolic associations in religion, mythology, superstition and philosophy. The seven classical planets resulted in seven being the number of days in a week. 7 is often considered lucky in Western culture and is often seen as highly symbolic. Evolution of the Arabic digit For early Brahmi numerals, 7 was written more or less in one stroke as a curve that looks like an uppercase vertically inverted (ᒉ). The western Arab peoples' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arab peoples developed the digit from a form that looked something like 6 to one that looked like an uppercase V. Both modern Arab forms influenced the European form, a two-stroke form consisting of a ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Panchromatic
A panchromatic emulsion is a type of photographic emulsion that is sensitive to all wavelengths of visible light, and produces a monochrome photograph—typically black and white. Most modern commercially available film is panchromatic, and the technology is usually contrasted with earlier methods that cannot register all wavelengths, especially orthochromatic film. In digital imaging, a panchromatic sensor is an image sensor or array of sensors that combine the visible spectrum with non-visible wavelengths, such as ultraviolet or infrared. Images produced are also black and white, and the system is used for its ability to produce higher resolution images than standard digital sensors. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
