Background •SPOT stands for Satellite Pour l'Observation de la Terre •The SPOT satellite Earth Observation System was designed by the Centre National d'Etudes Spatiales (CNES), in France. In 2014, twin satellite SPOT-7 was released in to orbit with the same capabilities. L'analyse diachronique d'images haute résolution permet de déceler les changements d'origine naturelle ou … Stopped functioning March 31, 2015. The two HRVIRs for High Resolution Visible and Infrared, are derived from the SPOT 1/2/3 design. types of remote sensing satellite data received by the sensor have different characteristics, so the potential utilization also vary. The SPOT orbit is polar, circular, sun-synchronous, and phased. Recommended for use in combination with other bands because of low contrast and sensitivity to haze, Best for showing roads and bare soils. The Moderate Resolution Imaging Spectrometer (MODIS) instrument is another satellite based instrument that continuously collects data over the Earth’s surface. Thus, it is able to take stereopair images almost simultaneously to map relief. Spot Image, a subsidiary of Astrium, funded the satellites alone and owned the system (satellites and ground segments) at time of launch. Temporal resolution is a measure of the repeat cycle or frequency with which a sensor revisits the same part of the Earth's surface. 1/4. Imaging is performed in three spectral bands. Operating on the same satellite orbit as SPOT-6, these satellites are able to provide a high temporal resolution (1 day revisit) which increases the opportunity to obtain a cloud-free image. Of the seven satellites put into orbit, two are still active: SPOT 6 and SPOT 7. PENDAHULUAN SPOT 4 carries the High Resolution Visible and Infrared sensor which is essentially the same as its predecessor with an extra infrared band. The satellite loads were identical, each including two identical HRV (High Resolution Visible) imaging instruments that were able to operate in two modes, either simultaneously or individually. Because the orbit of SPOT 1 was lowered in 2003, it will gradually lose altitude and break up naturally in the atmosphere. Since 1986 the SPOT family of satellites has been orbiting the Earth and has already taken more than 10 million high quality images. MODIS collects spectral information at several spatial resolutions including 250m, 500m and 1000m. The two spectral modes are panchromatic and multispectral. AL. SPOT 1 was launched with the last Ariane 1 rocket on February 22, 1986. Since 1986 the SPOT family of satellites has been orbiting the Earth and has already taken more than 10 million high quality images. SPOT 2 launched January 22, 1990 and deorbited in July 2009. This band is used to evaluate vegetation biomass and separates water from vegetation. In December 2014, SPOT 7 was sold to Azerbaijan's space agency Azercosmos, who renamed it Azersky. SPOT 6 and SPOT 7 are phased in the same orbit as Pléiades 1A and Pléiades 1B at an altitude of 694 km, forming a constellation of 2-by-2 satellites - 90° apart from one another. The intention has been to provide a complete set of images of the UK and Ireland for a range of applications which require consistent data quality over a wide coverage. Landsat data, for example, has a 30m resolution, meaning each pixel stands for a 30m x 30m area on the ground. The SPOT satellites orbit at an altitude of 822km. SPOT 2±- DQXDU\ . This subdivision into low, medium and high … "Satellite for observation of Earth") is a commercial high-resolution optical Earth imaging satellite system operating from space. Satellite imaging of the Earth surface is of sufficient public utility that many countries maintain satellite imaging programs. Imaging is performed in a single spectral band, corresponding to the visible part of the spectrum without the blue.

The frequency characteristics are determined by the design of the satellite sensor and its orbit pattern. Some of the more popular programs are listed below, recently followed by the European Union's Sentinel constellation. This band heightens the contrast between vegetated and non-vegetated areas. The panchromatic band has a resolution of 10 meters, and the three multispectral bands (G, R, NIR) have resolutions of 20 metres. The architecture is similar to that of the. In 2013, CNES lowered the altitude of SPOT 4 by 2.5 km to put it on a phased orbit with a five-day repeat cycle. Ask us for the Earth. Due to the finite storage capacity, a digital number is stored with a finite … SPOT 5 launched May 4, 2002 with 2.5 m, 5 m and 10 m capability. The series of SPOT satellites are a French initiative which started in 1986 with the launch of SPOT1. The SPOT satellites orbit at an altitude of 822km. Improvements of SPOT-5 compared to previous SPOT missions include: The scenes held by Mimas are panchromatic images covering the land mass of the British Isles. SPOT 1 was launched with the last Ariane 1 rocket on February 22, 1986. SPOT 5 has two high resolution geometrical (HRG) instruments that were deduced from the HRVIR of SPOT 4. It was initiated by the CNES (Centre national d'études spatiales – the French space agency) in the 1970s and was developed in association with the SSTC (Belgian scientific, technical and cultural services) and the Swedish National Space Board (SNSB). It has been designed to improve the knowledge and management of the Earth by exploring the Earth's resources, detecting and forecasting phenomena involving climatology and oceanography, and monitoring human activities and natural phenomena. The imaging is performed in four spectral bands: the same bands B1, B2, B3 as XS mode, plus a Short Wave Infrared band B4, covering 1.58 to 1.75 m. The pixel size is 20 metres. The intensity of a pixel is digitised and recorded as a digital number. The construction was initiated by Spot Image of Toulouse (France), and EADS Astrium in 2008, and officially announced in mid 2009, by Astrium Services’ CEO Eric Beranger. SPOT 4 launched March 24, 1998. 1.2.6.4. The temporal resolution specifies the revisiting frequency of a satellite sensor for a specific location and the availability of archive data over a specific location. SPOT 1, 2 and 3 carried a multi-spectral (XS) and panchromatic (P) sensor on board. Two days later, the 1800 kg SPOT 1 transmitted its first image with a spatial resolution of 10 or 20 meters.
