What is the spatial resolution of band 6?
120 meters
Spatial resolution for Band 6 (thermal infrared) is 120 meters, but is resampled to 30-meter pixels. Approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi).
What is the spatial resolution of Landsat 7?
Landsat 7 ETM+ images consist of eight spectral bands with a spatial resolution of 30 meters for bands 1 to 7. The panchromatic band 8 has a resolution of 15 meters.
How many pixels is a Landsat scene?
Landsat has 30 x 30 meter pixels which equates to 4.5 pixels per acre and a 16-day revisit cycle. A Landsat image (scene) is about 185 (e-w) x 175 km (n-s) (115 x 106 miles) and has overlap areas, particularly on the east and west sides, so fields fortuitously located in an overlap area have more imagery available.
Where is Landsat 6?
Landsat 6 was to circle the Earth in a sun-synchronous orbit at an altitude of 705 km (438 miles), inclined at 98.2 degrees (slightly retrograde), and the Worldwide Reference System-2 (WRS-2) path/row system.
What is the status of Landsat 7?
This 2021 publication describes the research conducted into the science capability of Landsat 7 ETM+ data, while the satellite is drifting in orbit. The USGS and NASA are planning for Landsat 7 to remain on-station and fulfilling its current science mission until Landsat 9 completes its commissioning.
What is Landsat resolution?
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).
What is the temporal resolution of Landsat 8 Oli?
Landsat 8 imagery has a radiometric resolution of 12-bits (16-bits when processed into Level-1 data products) compared to 8-bits for its predecessor.
What is the Landsat 7 used for?
Landsat 7 is the seventh satellite of the Landsat program. Launched on 15 April 1999, Landsat 7’s primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud-free images.
What are the features of the Landsat 7?
The Landsat 7 ETM+ instrument is designed with the significant exception of the thermal infrared band, where the ground resolution has been improved from 120 to 60 m. The ETM instrument incorporates a new 15 m panchromatic band, as well as a 9-bit analog to digital converter.
What are the band numbers for Landsat 4?
*Landsat MSS = the numbers shown are for Landsat 4 and Landsat 5; Landsat 1-3 band numbers are 4, 5, 6 and 7. Alan Belward from the European Union’s Joint Research Center discusses how Landsat helps his team promote sustainable development. Landsat Collections — What are Tiers?
When was Landsat 7 made free to the public?
The excellent data quality, consistent global archiving scheme, and reduced pricing ($600) of Landsat 7 led to a large increase of Landsat data users. In October 2008, USGS made all Landsat 7 data free to the public (all Landsat data were made free in January 2009 leading to a 60-fold increase of data downloads).
Why was the panchromatic band added to Landsat 7?
The panchromatic band was added to provide higher spatial landsat 7 resolution observations, as a compliment to the 30 m multispectral measurements. In order to limit the telemetered data stream to a reasonable volume, a 9-bit A-to-D system was designed so that either the upper or lower 8 bits of the radiometry could be provided from the system.
