What is spot in remote sensing?
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.
What is the spatial resolution of SPOT 5 images in pan band?
A spatial resolution of 10 m is provided in cross-track and 5 m (parallax direction) in along-track. The stereo acquisition mode can be sustained for scene lengths of up to 600 km.
What is the spatial resolution of spot?
SPOT-1 captured visible (reflected light) bands in the spectrum of green, red, and near-infrared bands (NIR) with a spatial resolution of 20 meters. The panchromatic image covers 0.51 to 0.73 µm in a single spectral band.
What is the full form of spot?
The SPOT (from French “Satellite pour l’Observation de la Terre”) series of missions has been supplying high-resolution, wide-area optical imagery since 1986.
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.
Is Indian satellite a SPOT?
SPOT 6 and SPOT 7 SPOT 6 was launched by India’s Polar Satellite Launch Vehicle on flight C21 at 04:23 UTC on 9 September 2012, while SPOT 7 was launched on PSLV flight C23 at 04:42 UTC on 30 June 2014.
What is SPOT imagery?
SPOT Image is marketing the high-resolution images, which SPOT can take from every corner of the Earth. SPOT 1 launched February 22, 1986 with 10 panchromatic and 20 meter multispectral picture resolution capability.
What is Landsat panchromatic image?
Panchromatic And Pansharpened Satellite Imagery. A panchromatic image uses a single band that combines Red, Green, and Blue bands, allowing for a greater spatial resolution. The resulting image does not contain any wavelength-specific information.
How many spectral bands does spot have?
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.
What are the sensors used in spot satellites?
SPOT Sensors
| Sensor | Resolution (m) | Spectral Bands (µm) |
|---|---|---|
| Vegetation Monitoring Instrument (VMI) | 1,000 | 0.45-0.52 (blue) |
| 0.61-0.68 (red) | ||
| 0.78-0.89 (near IR) | ||
| 1.58-1.75 (mid-IR) |
When was spot started?
Series Background. Initiated by the French space agency CNES in 1977 and run by Spot Image, based in Toulouse, France, SPOT was the first European Earth-observation satellite programme. The series was developed in association with Belgian and Swedish institutions.
