What is Landsat 7 ETM+ SLC-off data?
Landsat 7 ETM+ SLC-off 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 collected prior to the SLC failure.
The Landsat 7 satellite acquired science data until January 19, 2024.

Why do Landsat 7 Level-1 products contain two thermal bands? Why do Landsat 7 Level-1 products contain two thermal bands?
Landsat 7 acquired thermal data in two bands from one detector in both high (Band 6H) and low (Band 6L) gain. The difference in gain settings is important to different types of studies (i.e., clouds vs. deserts). Aside from the resolution differences and saturation on the high and low ends, the two bands provide the same Digital Numbers (DN) for every pixel. FILE_NAME_BAND_6_VCID_1 (band 61 or 6L)...
What Landsat products are available? What Landsat products are available?
There are several Landsat Collection 2 products that are useful for science applications and land use/land change studies: Landsat Level-1 Products - Each Level-1 product includes individual spectral band files, a metadata file, and additional ancillary files. Level-1 products are available for all global landmasses. Landsat U.S. Analysis Ready Data (ARD) - U.S. ARD uses Landsat Level-1 data as...
What are Landsat 7 SLC-off Gap Mask files? What are Landsat 7 SLC-off Gap Mask files?
Band-specific gap mask files are included with every Landsat 7 Scan Line Corrector (SLC)-off Level-1 data product. These ancillary data identify the location of all pixels affected by the original data gaps in the primary SLC-off scene. The gap mask is provided as a series of individual band files, in compressed (GZIP) GeoTIFF format. Gap Mask Legend Values: green = primary scene blue = fill scene...

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. Go to Landsat Known Issues for details about anomalies that have been discovered and investigated.

The Spectral Characteristics Viewer is an interactive tool that can be used to visualize how the bands, or channels, of different satellite sensors measure the intensity of the many wavelengths (colors) of light. This is also known as the relative spectral response (RSR). By overlaying the spectral curves from different features (spectra), one can determine which bands of the selected sensor will...

The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey. On July 23, 1972, in cooperation with NASA, the Earth Resources Technology Satellite (ERTS-1) was launched. It was later renamed Landsat 1. Additional Landsat satellites have launched to bring the world an archive of remote sensing data. Currently orbiting and active...

Landsat 7 Captures Hurricane Ian Aftermath
On October 2, 2022, this gap-filled Landsat 7 image captured brownish-black sediment runoff from rivers and streams on the southwest coast of Florida. These are the first Landsat images after Hurricane Ian devastated the area on Wednesday, September 28. Water runoff can carry away debris, fertilizers, metals, and other pollutants.

What is Landsat 7?
In 1992, The U.S. Congress authorized the procurement, launch, and operation of a new Landsat satellite. This new system, Landsat 7, was launched in April 1999. It is the latest in a series of Earth observations satellites dating back to 1972.
