What is the spatial resolution of SPOT 7?
What is the spatial resolution of SPOT 7?
Two identical NAOMI instruments on board SPOT 7 provide data up to 1.5 m spatial resolution panchromatic and multispectral. They are able to operate in two modes, either simultaneously or individually. In simultaneous mode the swath is 120 km2 and individual mode the swath is 60 km2.
When and where was the first SPOT satellite launched?
Initiated in 1977 by France, SPOT was the first European Earth-observation satellite programme (SPOT comes from the French ‘Satellites Pour l’Observation de la Terre’). Between 1986 and 2002, five SPOT satellites were launched from Kourou.
What is Pleiades imagery?
The Pléiades satellite constellation provides very high-resolution optical imagery that delivers an extremely high level of detail. Designed for civil and military users, the system is especially suited for emergency response and change detection.
How many SPOT satellites are there?
There have been four SPOT (Satellite Pour l’Observation de la Terre) satellites launched since 1986, providing medium to high resolution of the Earth’s surface. SPOT 1, 2 and 3 carried a multi-spectral (XS) and panchromatic (P) sensor on board. SPOT 4 was successfully launched in March 1998.
What type of satellite is spot?
About SPOT Series The latest satellites in the series, SPOT 6 and SPOT 7, are commercial satellites owned by Airbus Defence and Space, and assure data continuity through to 2024. All of the SPOT satellites provide imagery in panchromatic and multispectral bands with a swath of 60 km.
What does Ikonos stand for?
Greek for image
IKONOS (Greek for image) was one of the first commercial satellites to serve imagery to the public. In 2000, it was a big upgrade with blue, green, red, and near-infrared (NIR) at 4-meter resolution. In addition, it collected 1-meter panchromatic images and stereo imagery.

Who made SPOT satellite?
the French National Centre for Space Studies
About SPOT Series Conceived by the French National Centre for Space Studies (CNES), five satellites were launched between 1986 and 2015, and in revealing Earth’s surface in detail they led to new applications in mapping, vegetation monitoring, land use and land cover, and the impacts of natural disasters.
Is Pleiades imagery free?
Everything in Pleiades is free to reuse under the terms of an open license.
What is the highest resolution satellite imagery?
The Maxar satellite constellation provides the highest-resolution (natively collected) imagery in the commercial market. We collect about 680,000 sq km of 30 cm imagery every day, providing an abundant inventory to create 15 cm HD.
What is SPOT satellite used for?
SPOT (Satellite Pour l’Observation de la Terre), France The SPOT program consists of a series of optical remote sensing satellites with the primary mission of obtaining Earth imagery for landuse, agriculture, forestry, geology, cartography, regional planning, water resources and GIS applications.
When did Landsat 7 break?
May 31, 2003
Landsat 7 Scan Line Corrector (SLC) Failure On May 31, 2003, the Scan Line Corrector (SLC), which compensates for the forward motion of the satellite, failed. Subsequent efforts to recover the SLC were not successful, and the failure is permanent.
