Data Products and Browse Images

Landsat 7 ETM+ SLC-off data refers to all Landsat 7 images collected after May 31, 2003, when the Scan Line Corrector (SLC) failed. These products have data gaps, but are still useful and maintain the same radiometric and geometric corrections as data...
LandsatLook images are full resolution .jpeg files that are included as options when downloading Landsat data from EarthExplorer, GloVis, or via the LandsatLook Viewer.The following products are available, and are useful for image selection and visual...
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...
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...
The gridlines on the SLC-off browse images give a visual impression of the distribution of image effects caused by the scan line corrector failure.Examples and details are located on the Landsat SLC-off Browse Image page.
Black Landsat browse images are night (ascending) scenes, which are occasionally acquired for rows 123 to 246. Black scenes with a bright oval (candle flame) are Partial Aperture Calibration (PAC) scenes, also acquired during the ascending node.Both...
Apparently, the color stretch used by the processing system to create browse images for Landsat TM images does not perform well in areas of low contrast. The resulting browse images are of very low quality and probably do not indicate the real quality of...
Pixelation is an artifact of the browse generation process and is common for scenes that are located over flat, low-contrast areas, such as water, sand and snow. The actual data will not appear this way.A linear shift in color midway through a scene is...
A custom color stretch is performed on the images, based on individual scene content. Scenes from within the same area and/or acquisition date may vary in band content (due to differences such as cloud content or ground moisture). This differing content...
