Which is hyperspectral sensor?
Hyperspectral sensors acquire imagery in hundreds of narrow, contiguous spectral bands, which facilitates fine discrimination between different features on the Earth’s surface. It is a complementary data source to Synthetic Aperture Radar (SAR) and conventional multi-spectral data.
What is spaceborne sensor?
In spaceborne remote sensing, sensors are mounted on-board a spacecraft (space shuttle or satellite) orbiting the earth. At present, there are several remote sensing satellites providing imagery for research and operational applications.
Is Sentinel a hyperspectral?
The SENTINEL-2 Multispectral Instrument (MSI) samples 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution.
What are hyperspectral sensors used for?
Hyperspectral imaging measures continuous spectral bands, as opposed to multiband imaging which measures spaced spectral bands. Engineers build hyperspectral sensors and processing systems for applications in astronomy, agriculture, molecular biology, biomedical imaging, geosciences, physics, and surveillance.
Is Modis a hyperspectral?
Moderate resolution Imaging Spectrometer (MODIS). 36 bands, spectral range between 405 -14385 nm with a slit width about 20 nm, depending on bands. Spatial resolution, 250 to 1000 m, depending on bands.
How does a hyperspectral sensor work?
Hyperspectral imaging (HSI) is a technique that analyzes a wide spectrum of light instead of just assigning primary colors (red, green, blue) to each pixel. The light striking each pixel is broken down into many different spectral bands in order to provide more information on what is imaged.
What are spaceborne platforms?
In space borne remote sensing, sensors are mounted on-board a spacecraft (space shuttle or satellite) orbiting the earth. Space borne platforms include the following: •Rockets, Satellites and space shuttles. Space borne platforms range from 100 to 36000 km. above the earth’s surface.
What are the 3 remote sensing platforms?
There are three broad categories of remote sensing platforms: ground based, airborne, and satellite.
Is Sentinel-2 a hyperspectral?
While hyperspectral exploratory sensors are demonstrating their potential, Sentinel-2 multispectral satellite remote sensing is now providing free, open, global and systematic high resolution visible and infrared imagery at a short revisit time.
What is Sentinel-2 MSI?
Sentinel-2 is a wide-swath, high-resolution, multi-spectral imaging mission supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
What type of sensor is MODIS?
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a satellite-based sensor used for earth and climate measurements.
