Landsat 8 data products are processed to be consistent with the existing Landsat 1 to Landsat 7 Level-1 data products.The Level 1 Product and LandsatLook (full-resolution jpg) files are available for download at no charge from GloVis, EarthExplorer or...
The Worldwide Reference System (WRS) is a global notation used in cataloging Landsat data. Landsat 8 and Landsat 7 follow the WRS-2, as did Landsat 5 and Landsat 4. Landsat 1, Landsat 2, and Landsat 3 followed WRS-1.Shape files for WRS-1 and -2 (path/row...
The LDCM Long Term Acquisition Plan (LTAP-8) and the Landsat 7 Long Term Acquisition Plan (LTAP) direct the acquisition of Landsat 8 and Landsat 7 scenes, respectively. Seasonality, land definition, historical cloud cover, gain settings, and sun angle...
Landsat 8's Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) sensors provide improved signal-to-noise (SNR) radiometric performance quantized over a 12-bit dynamic range.This translates into 4096 potential grey levels in an image compared...
The percentage of cloud cover is calculated when raw mission data from Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) are processed to Level-0R during ingest into the archive using the Automatic Cloud Cover Assessment (ACCA)...
These pages provide the latest details and product information about each Landsat sensor:Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS)Landsat 7 Enhanced Thematic Mapper Plus (ETM+)Landsat 4-5 Thematic Mapper (TM)Landsat 1-5...
The Landsat satellites are not considered tasking, and data acquisition requests are not available to the general public. The Long Term Acquisition Plans for both Landsat 8 and Landsat 7 direct the daily acquisitions of satellite data.The Landsat...
A few common anomalies occasionally seen in Landsat data include dropped scan lines, Memory Effect, and detector failure.   A more complete list and details on anomalies discovered and investigated can be found on the Landsat Anomalies Web page.
Landsat browse images are displayed as false color RGB composites using the following band combinations:Landsat 8 OLI: Bands 6,5,4. Pixels are resampled from the original 30 meter data to 180 meters.Landsat 7 ETM+ SLC-off (July 2003 to present): 5,4,3...
Along with similar multispectral bands used on the Landsat 7 ETM+ sensor, the addition of a new coastal/aerosol band and a new cirrus band provides improved data products. Two thermal bands (TIRS) capture data with a minimum of 100 meter resolution, but...
