DubaiSat-1
DubaiSat-1 ( ar, دبي سات-1) is a remote sensing Earth observation satellite built by the '' Emirates Institution for Advanced Science and Technology (EIAST)'' under an agreement with Satrec Initiative, a satellite manufacturing company in South Korea. DubaiSat-1 was launched on 29 July 2009 into a 680 km altitude sun-synchronous polar orbit from the Baikonur launch site in Kazakhstan, along with several other satellites on board the Dnepr launch vehicle. Overview DubaiSat-1 observes the earth at a Low Earth orbit (LEO) and generates high-resolution optical images at 2.5 m in panchromatic (black-and-white) and at 5 m in multispectral (colour) bands. These images provide decision makers in the UAE as well as EIAST clients with a valuable tool for a wide range of applications including infrastructure development, urban planning, and environment monitoring and protection.

Dnepr (rocket)
The Dnepr rocket (russian: Днепр, translit=Dnepr; uk, Дніпро, translit=Dnipró) was a space launch vehicle named after the Dnieper River. It was a converted ICBM used for launching artificial satellites into orbit, operated by launch service provider ISC Kosmotras. The first launch, on April 21, 1999, successfully placed UoSAT-12, a 350 kg demonstration mini-satellite, into a 650 km circular Low Earth orbit. History The Dnepr was based on the R-36 (missile), R-36MUTTH Intercontinental ballistic missile (ICBM)called the ''SS-18 Satan'' by NATOdesigned in the 1970s by the Yuzhnoe Design Bureau in Dnepropetrovsk, Ukrainian SSR. The Dnepr control system was developed and produced by the Khartron, JSC "Khartron", Kharkiv. The Dnepr was a multistage rocket, three-stage rocket using storable hypergolic liquid propellants.

Geosciences
Earth science or geoscience includes all fields of natural science related to the planet Earth. This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres, namely biosphere, hydrosphere, atmosphere, and geosphere. Earth science can be considered to be a branch of planetary science, but with a much older history. Earth science encompasses four main branches of study, the lithosphere, the hydrosphere, the atmosphere, and the biosphere, each of which is further broken down into more specialized fields. There are both reductionist and holistic approaches to Earth sciences. It is also the study of Earth and its neighbors in space. Some Earth scientists use their knowledge of the planet to locate and develop energy and mineral resources. Others study the impact of human activity on Earth's environment, and design methods to protect the planet. Some use their knowledge about Earth processes such ...

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] |
Multispectral Image
Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum. The wavelengths may be separated by filters or detected with the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, i.e. infrared and ultra-violet. It can allow extraction of additional information the human eye fails to capture with its visible receptors for red, green and blue. It was originally developed for military target identification and reconnaissance. Early space-based imaging platforms incorporated multispectral imaging technology to map details of the Earth related to coastal boundaries, vegetation, and landforms. Multispectral imaging has also found use in document and painting analysis. Multispectral imaging measures light in a small number (typically 3 to 15) of spectral bands. Hyperspectral imaging is a special case of spectral imaging where often hundreds of contiguous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrastructure
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, tunnels, water supply, sewerage, sewers, electrical grids, and telecommunications (including Internet access, Internet connectivity and Broadband, broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing Commodity, commodities and services essential to enable, sustain, or enhance societal quality of life, living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to Climate change mitigation, mitigate and Climate change adaptation, adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and gre ...

Remote Sensing
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. The term is applied especially to acquiring information about Earth and other planets. Remote sensing is used in numerous fields, including geography, land surveying and most Earth science disciplines (e.g. hydrology, ecology, meteorology, oceanography, glaciology, geology); it also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others. In current usage, the term ''remote sensing'' generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation). It may be split into "active" remote sensing (when a signal is emitted by a satellite or aircraft to the object and its reflection detected by ...

The World (archipelago)
The World Islands (Arabic: جزر العالم; ''Juzur al-Ālam'') are an archipelago of small artificial islands constructed in the shape of a world map, located in the waters of the Persian Gulf, off the coast of Dubai, United Arab Emirates. The World Islands are composed mainly of sand dredged from Dubai's shallow coastal waters, and are one of several artificial island developments in Dubai. The World's developer is Nakheel Properties, and the project was originally conceived by Sheikh Mohammed bin Rashid Al Maktoum, the ruler of Dubai. The construction was done by two Dutch (joint venture) specialist companies, Van Oord and Boskalis. The same companies also created the Palm Jumeirah. Construction of the 300 islands began in 2003, before being halted due to the financial crisis of 2007–2008. Though 60% of the islands were sold to private contractors in 2008, development on most of the islands has not started. As of July 2012, Lebanon Island was developed and was the only i ...
