Land Use And Land Cover
Data acquisition requests are not available to the public. The Landsat 8 and Landsat 7 satellites each acquire data on a continual basis in accordance with their respective Long Term Acquisitions Plans.
A number of artifacts and anomalies can happen to any remote sensing data. Banding, dropped scan lines, and detector failures are only a few of the anomalies that can be seen in Landsat data.
Each Landsat 8 scene comes with eleven individual band files, one quality band file, one metadata file, and one angle coefficients file.
GeoMAC only displays perimeter data as they are submitted.
Landsat Multispectral Scanner (MSS) images consist of four spectral bands with 80 meter spatial resolution. Approximate scene size is 170 km north-south by 185 km east-west (106 mi by 115 mi).
This is a common question considered by all users of remotely sensed data.
Landsat data products can be downloaded at no charge from the following sites:
Both Landsat 7 and Landsat 8 orbit the Earth at an altitude of 705 kilometers (438 miles) in a 185-kilometer (115-mile) swath, moving from north to south over the sunlit side of the Earth in a sun synchronous orbit, following the
Landsat scenes directly downlinked to the EROS Landsat Ground Station become available through EarthExplorer or GloVis within 24 hours after acquisition.
Because Landsat 8 data includes additional bands, the combinations used to create RGB composites differ from Landsat 7 and Landsat 5. For instance, bands 4, 3, 2 are used to create a color infrared (CIR) image using Landsat 7 or Landsat 5.
