The 2.5 m images were used by the U.S. government for logistics planning prior to deploying personnel to Haiti and later to manage resources on the ground. Thousands of new, high-quality pictures added every day. The Danish city is a good model in terms of urban planning and design, and is working towards becoming carbon-neutral by the year 2025. Launched on May 4, 2002, SPOT-5 produced nearly 13 years worth of earth imagery at a Ground Sampling Distance (GSD) of 2.5m (Panchromatic). The Image Spot’s compact, lightweight design provides an impressively bright output of 3000 lumens using a mere 45 watts of power. Many of those killed fell victim to landslides and damage to buildings caused by the heavy rain and wind. SPOT-5/TAKE5 supplies data every 5 days, with a resolution closer to Sentinel-2's (10 m) and over a more convenient period for summer crop monitoring in temperate zones (April to September 2015). Every day a new image of the global vegetation status is being processed, archived and distributed at the Image Processing Center of VITO in Belgium. During this period, the TAKE5 experiment has been providing images every 5 days over 150 sites selected after an international call for sites. Three stored, compression factor: 2.6-3.0, Table 6: Overview of performance parameters of the SPOT family, Figure 21: Comparison of spacecraft bus sizes of the SPOT series, Improved attitude restitution for SPOT-5 (commissioning phase issues), An extra attitude restitution process has been developed in order to provide an accurate attitude for the imagery location model. The observation coverage of each HRG is 60 km in the nadir direction and >80 km in the oblique configuration (same two-swath coverage as before). - 25 Years of SPOT Satellites: Since February 22, 1986, SPOT satellites have been keeping a watchful eye on the Earth. 17). - Scientific "external" sites selected by ESA, as a result of an international call for proposals to the worldwide users' community. All five of the SPOT satellites were developed and built by Astrium as prime contractor, responsible for the platform and high-resolution imaging system. The SPOT-5 local hour is slowly drifting since maneuvers for inclination correction are no more performed (hydrazine is saved for end of life operations). B2 (0.61-0.68 µm), 10 m SPOT-5 Satellite Image Gallery The coverage offered by SPOT-5 is a key asset for applications such as medium-scale mapping (at 1:25 000 and 1:10 000 locally), urban and rural planning, oil and gas exploration, and natural disaster management. Daily change detection reports were delivered to subscribers free of charge March 17-25. It is designed as a constellation of twin polar-orbiting satellites in the same orbit to fulfil revisit and coverage requirements. Brown bear and wolf also once roamed this area, but have disappeared through human influence and changes in the ecosystem over hundreds of years. Stopped tracking on August 2, 1993. 15), • The SPOT-5 commercial mission was ended on March 27, 2015 — after nearly 13 years of good services. Moreover, the SPOT-5 system designed for its commercial mission had to be reconfigured to this new mission, involving different needs, within a short time. The IP40 model connects to DMX & DALI via standard RJ45/Cat5 cable, while the IP65 units connect via a factory-installed, exterior-rated hybrid cable. Compression ratios of 2.8 are used. 29), - After the devastating Japanese earthquake of March 11, 2011, SPOT-5 was tasked by the International Charter on Space and Major Disasters to cover the coast that took the full force of the subsequent tsunami. 13). The HRS instrument was developed and built by EADS Astrium SAS, sponsored by CNES and SPOT IMAGE. But SPOT-5 isn't dead yet: following the success of the Take 5 experiment on SPOT-4, a new edition, co-funded by ESA, was decided for SPOT- 5. 26). Suivi de l’environnement : Les images du capteur VEGETATION sont utilisées pour suivre l'évolution des écosystèmes continentaux. Recognized this year as the European Green Capital, Copenhagen (Capital of Denmark) has set a prime example with investments in sustainable technology, forward-thinking public policy and an educated and active public. • The commissioning phase of the spacecraft and its instruments was completed on July 12, 2002. Artist's rendition of the SPOT-6 & SPOT-7 satellite constellation (image credit: EADS Astrium) As of … Operational activities ceased at the end of 1990, SPOT-1 was reactivated on March 20, 1992). SPOT-5 et son capteur panchromatique (résolution de 5 m et 2,5 m en super-mode) permet la réalisation de cartes au 1:50 000. MVS actively controls the instrument's temperature and provides the ancillary systems required to operate it (chiefly power and TM/TC). SPOT-7 can also collect stereo and tri-stereo images in one pass. Compression ratios of 2.28-2.8 are achieved depending on imaging mode.

The two PAN detector lines are offset in the focal plane in such as way as to provide coincident imagery of the same instantaneous cross-track area, each at a spatial resolution of 5 m. [Note: The dual array in the focal plane (offset by one half pixel in one direction and 3.5 pixels in the other to avoid overlapping) is sufficient to improve the sampling grid without doubling each array's acquisition rate. Onboard data compression of source data is provided with DCT (Direct Cosine Transform) of HRG and HRS data streams. • April 30, 2014: The SPOT-Vegetation mission, flown on SPOT-5 and SPOT-4, has been delivering images on the global vegetation status to more than 10,000 users worldwide on a daily basis. The stricken Fukushima Dai-ichi nuclear power plant and its surroundings are still under surveillance and periodic reports will still be delivered over the next few months. Stereo and Tri-Stereo modes available on SPOT-6 and -7 and Pleiades are also available. It is possible to combine the two 5 m pixel image samples into four new slightly overlapping image samples of about 3 m pixel size. Measuring in at 7.8in x 4.8in x 3.2in (198mm x 121mm x 81mm) with a weight of 5.5 lbs (2.5 kg), the Image Spot can be installed … All rights reserved. 30). 1), The overall mission objectives are: 2) 3) 4). Brussels is the de facto capital of the EU, and is a major center for international politics. Legend to Figure 8: Zooming in on the city, one can see a number of large parks, such as the Parc du Cinquantenaire or "Park of the fiftieth anniversary," a large public, urban park (30 hectares) in the easternmost part of the European Quarter in Brussels — home to the institutions of the European Union. Currently, an operational life to mid-2015 is expected (Ref. 6000 MS (3 lines) The downlink is in X-band (QPSK modulation) at a data rate of 2 x 50 Mbit/s. This proposal was agreed to by ISPRS and given the name of HRS-SAP (High Resolution Stereoscopic-Scientific Assessment Program). 45) 46), Figure 22: The star tracker on the space-facing side of the satellite between the two HRG instruments (image credit: CNES). Data is automatically geo-referenced using an automated system that operates at an accuracy of 10 to 20 meters after calibration. The Sentinel-2 satellites and mission: ESA (European Space Agency) is developing and operating Sentinel-2, a next-generation Earth observation mission, within the Earth observation and monitoring program Copernicus of the European Commission. The new SPOT 5.6 software supports 4K UltraHD when using our new Insight 5MP and 12Mp cameras. ESA is offering free of charge for scientific research and application development access to the following SPOT collections: 11), - ESA SPOT archive collections (ESA online archive), - Archived SPOT-1 to -5 all production levels (on demand), - Archived and new SPOT-6 & -7 (acquisition modes: single ,stereo or tri-stereo) all production levels (on demand and standard service for tasking). These users (cartographers, urban planners, environmental experts, foresters, agronomists,) have concluded that the supermode resolution is about 3 m (between 2.5 m and 3.5 m depending on applications and analyzed features). The S/C structure has dimensions of: 3.4 m x 3.1 m x 6 m (excluding the solar array). VITO developed the user segment and is responsible for the operations, calibration and distribution of all imagery. The Sentinel-2 mission focuses on global land monitoring at high resolution with high revisit capability. The detection unit, mounted in the instrument's focal plane, converts the light signal from the optical subassembly into electric signals for processing by the video electronics units. • In January 2010, hours after the devastating January 12 earthquake struck Haiti, Spot Image personnel were in nearly constant communications with key customers and other organizations that needed access to imagery to assist in disaster response efforts. (InGaAs/InP), 6000 PAN, ESA has carefully evaluated these proposals and selected more than 60 sites for the acquisition plan. At this point, CNES handed over the responsibility for commercial operation of the SPOT-5 system to Spot Image (Ref. • May 12, 2014: The current status of the SPOT-5 mission is nominal and the mission is going to be extended until the end of the month of March 2015 (Ref. These 2 satellites will supply high resolution images with a large coverage (systematic acquisition of all lands, 290km swath) and high repetivity (5 days with 2 satellites). - The products can be made available for free through a project proposal submission via the SPOT information area and Pleiades information area on ESA's Earth Online Portal. There the data was used to generate maps of the stricken area for distribution to Non-Governmental Organizations aiding in the response. In January 1999, a further functional improvement was introduced giving the HRS (High Resolution Stereoscopic) instrument a full stereoscopic capability. The great success of TAKE5 with SPOT-4 was confirmed by ESA's decision to largely contribute to the renewal of TAKE5 experiment using SPOT5. Thank you, Haron Xaud. A new quincunx sampling mode was adopted referred to as THR (Très Haute Résolution) or very high resolution mode. See description of instrument under SPOT-4 and under TOPEX/Poseidon. See trending images, wallpapers, gifs and ideas on Bing everyday. The Vegetation instruments (VGT-1 and VGT-2) were incorporated in the SPOT program, a program that was founded in 1978. 20). Thanks to this orbit, it will be possible to acquire data over selected sites every 5 days under constant angles for duration of around 5 months over the majority of the vegetation phase (current assumed schedule 08/04/15-31/08/15). Available in many resolutions, SPOT 6/7 offers continuity of the SPOT constellation first launched in 1986. Find spot 5 differences stock images in HD and millions of other royalty-free stock photos, illustrations and vectors in the Shutterstock collection. Operational as of 2007. When the user presses a hotspot, a popup containing a header and text or video is displayed. The situation regarding Japan's nuclear power plants recently prompted Astrium GEO-Information Services to activate its "SPOTMonitoring" service over the area. The S/C mass is 3030 kg at launch, power = 2400 W (EOL), batteries = 4 x 40 Ah, design life = 5-7 years. 27), Figure 11: Projected service profile of the SPOT family (image credit: ), • The SPOT-5 spacecraft and its payload are operating nominally in 2012 (10th year of on-orbit operations). 31). To limit download time, it is only provided here at 60 m resolution. This huge volume of data will be a revolution for vegetation monitoring by satellite: it will change and enhance the way land surfaces are monitored using remote sensing and such an evolution needs to be prepared. B3 (0.78-0.89 µm), 10 m • The final issue deals with optimization of time delay between two HRG off-nadir image acquisitions. The SPOT Basic image capture software enables microscopists to … Stereo satellite imagery is vital for applications that call for 3D terrain modeling and computer environments, such as flight simulator databases, pipeline corridors, and mobile phone network planning. 32). - The products are available in level 1 and level 3 (levels 1A/1B and orthorectified level 3 for SPOT-1 to -7, primary and orthorectified levels for Pleiades). • SPOT-5 was launched on May 4, 2015, the first image was received after 3 days on May 7, 2015. SWIR(1.58-1.7µm), 20 m, Detector line array (Si) - In December 2014, ESA launched a call for proposals of sites in order to choose the areas for which the observation data processing cost will be funded by ESA's Earthnet program. - The city of Leuven (Dutch), or Louvain (French) in the Flemish region of Belgium can be seen in the upper right corner of the image. SPOT-4 has been deactivated a couple of years ago, but SPOT-5 will still be delivering images of the Earth until the end of May 2014. 3.5 m x 3.5 m dual image, Catadioptric Schmidt telescope with a spherical mirror (SPOT-4 heritage), Table 2: Specification of the HRG instrument. • The third item is to turn HRS stereo pairs parallax into a precise enough altitude estimate. all at 20 m resolution, B1 (0.50-0.59 µm), 20 m 2HRVIR, Vegetation, SILEX, PASTEC, POAM-3, DORIS. This higher spatial resolution is also in line with the upcoming Sentinel-3 mission, hereby offering users the prospect of an uninterrupted times series of 25 years or more. Tests performed during in-orbit checkout have shown that: 35), - the satellite, ground telemetry and command systems, and passenger instruments are functioning perfectly and system availability is excellent. - On May 31, 2014, the SPOT-Vegetation program will hand over the torch to PROBA-V. PROBA-V is an ESA minisatellite mission designed and built by a Belgian consortium (QinetiQ Space NV, Belgium). 25). A straightforward processing of this image type indicates if the mirror command can be improved. In analogy to the previous SPOT-4 Take 5 experiment, within this timeframe a new experimental phase should allow placing SPOT-5 in a 5 days cycle orbit. - SPOTMaps 2.5 m complete dataset (on demand). The main components of the HRG instrument are: • Stable structure supporting its mechanisms. Sentinel-2A was launched on 23 June 2015, the second satellite Sentinel-2B should follow by the end of 2016. The experience acquired from SPOT-4/TAKE5 was only partially useful as the SPOT-4 and SPOT-5 systems are quite different and the constraints were not the same with SPOT-5. In 1996, the SPOT-5 program was downsized (to one orbiting S/C) and redefined to improve the spatial resolution of the imagery below 5 m. As a result, an innovative image acquisition and processing scheme has been developed by CNES to obtain spatial resolutions of about 3 m from two 5 m images. 36) 37) 38), Figure 18: Alternate view of the supermode scheme (image credit: SPOT Image). Archived SPOT-5 Satellite Imagery will remain available. The VGT-2 instrument, incorporated onto the SPOT-5 satellite, was sent into orbit on May 4, 2002. Image: Astrium/SAS Image: Astrium/SAS. Figure 4: The SPOT-5/TAKE5 sites of interest (image credit: CNES), • April 10, 2015: The SPOT-1 to -5 mission archive, the SPOT-6 and -7 mission archive and new acquisitions, the Pleiades mission archive and new acquisitions, and the SPOTMAPS 2.5 complete dataset are now available to the scientific user community. Although the magnetic recorders provided more capacity (120 Gbit), the file management system allocates available storage capacity more efficiently. 33), • The spacecraft and its instruments are operating nominally in 2009. SPOT-7 is planned to operate in a circular orbit at 695 Kilometers at an inclination of 98.2 degrees. Background: In 1994 the SPOT-5 program was approved by the French government, consisting initially of two identical S/C in orbit and two new optical imagers for these S/C, called HRG (High Resolution Geometric) and HRS (High Resolution Stereoscopic) to provide a ground resolution of 5m.
