What is the spatial resolution in Metres of Landsat 8 products in the visible spectrum?
30 meters
The Landsat 8 satellite payload consists of two science instruments—the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). These two sensors provide seasonal coverage of the global landmass at a spatial resolution of 30 meters (visible, NIR, SWIR); 100 meters (thermal); and 15 meters (panchromatic).
How often does Landsat 8 capture imagery of the same location on the Earth’s surface?
Each satellite makes a complete orbit every 99 minutes, completes about 14 full orbits each day, and crosses every point on Earth once every 16 days. The satellite orbits are offset to allow 8-day repeat coverage of any Landsat scene area on the globe.
How many bands can Landsat 8 collect at once?
11 spectral bands
Landsat-8 collects 11 spectral bands varying from 15-meter to 100-meter resolution. Multispectral Scanner (MSS) collected data in green, red and two near-infrared bands with a 60 meter pixel size.
What is the spatial resolution of Landsat 8’s multispectral imagery?
Landsat 8 medium spatial resolution multispectral imagery presents particular interest in extracting land cover, because of the fine spectral resolution, the radiometric quantization of 12bits, the capability of merging the high resolution panchromatic band of 15 meters with multispectral imagery of 30 meters as well …
What is Oli in remote sensing?
The Operational Land Imager (OLI) is a remote sensing instrument aboard Landsat 8, built by Ball Aerospace & Technologies. Landsat 8 is the successor to Landsat 7 and was launched on February 11, 2013. OLI is a push broom scanner that uses a four-mirror telescope with fixed mirrors.
What is Landsat MSS?
The Landsat Multispectral Scanner (MSS), a sensor carried on Landsats 1 through 5, acquired four spectral bands of radiant energy from the earth’s surface. The wavelength range for the MSS sensor is from the visible through the near-infrared portion of the electromagnetic spectrum.
