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 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.
What is SPOT imagery?
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. 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.
What is spatial resolution sensor?
Spatial resolution is a measure of the smallest object that can be resolved by the sensor, or the ground area imaged for the instantaneous field of view (IFOV) of the sensor, or the linear dimension on the ground represented by each pixel.
What is the radiometric resolution for SPOT 5?
SPOT 5 had two HRG instruments that were deduced from the HRVIR of SPOT 4. They offered a higher resolution of 2.5 to 5 metres in panchromatic mode and 10 metres in multispectral mode (20 metre on short wave infrared 1.58 – 1.75 µm).
What is the spatial resolution of Landsat 8?
30 meters
Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) images consist of nine spectral bands with a spatial resolution of 30 meters for Bands 1 to 7 and 9.
What is the characteristics of spot?
The SPOT satellites orbit at an altitude of 822km. SPOT scene sizes are typically 60km by 60km (vertical viewing) or 60km by 80km for oblique viewing. The optical imaging instruments (HRVs) are steerable to either side of the ground track – east to west – by up to 30 degrees.
What are spot sensors?
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 spatial resolution in vision?
Resolution (SPATIAL RESOLUTION) is the ability to see fine detail in an image; it can be quantified by separation of two distinguishable points.
What is the spatial resolution of Sentinel 2?
10 m to 60 m
Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters.
What is the spatial resolution of the SPOT-5?
The HRG sensor on board of SPOT-5 provides spatial resolution of the imagery to < 3 m in the panchromatic band and to 10 m in the multispectral mode (3 bands). The SWIR band imagery remains at 20 m.
What is the FOV of the spot HRG instruments?
Two HRG instruments are provided in the conventional SPOT-series double-observation configuration, each with a FOV of 4.13º and the same cross-track pointing capabilities of ±27 º as the HRVIR imager on SPOT-4.
What is the spatial resolution of the HRS?
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. HRS uses the same CCD line detector design as for the HRG instrument. 22)
What is the operational life expectancy of SPOT-5 and hrg-2 sensors?
– On April 1, 2011, a refocusing has been performed on the HRG-2 sensor. The result of this action is to recover the instrument’s beginning-of-life performances (for relative and absolute FTM, and auto-test calibration).- The operational life expectancy of SPOT-5 remains unchanged, the estimate is for mid-2015. 12)
