: If your software supports it, consider downloading the newer MTL.txt (Metadata) files provided with GeoTIFF products, as these have replaced the older NDF formats in most modern workflows. Landsat 7 | U.S. Geological Survey - USGS.gov
: These .txt files are used by GIS software (like ENVI or ERDAS IMAGINE) to correctly "place" the imagery on a global grid.
: These files are officially generated and distributed by the U.S. Geological Survey (USGS) through platforms like EarthExplorer.
: Only download satellite metadata from authorized sites like USGS EarthExplorer or NASA Earthdata to ensure the integrity of the science data.
: Files from official sources like the USGS are highly reliable and essential for accurate radiometric calibration of satellite imagery.
: Ensure the filename matches the specific scene ID of the Landsat imagery you are processing.
: It acts as a metadata header, containing parameters such as map projection, corner coordinates, and sensor-specific details (e.g., for the Enhanced Thematic Mapper Plus (ETM+) instrument).
: Because it is a plain text file, it can be opened in any text editor for manual inspection of metadata, such as acquisition dates or cloud cover percentages. Downloading Advice If you are looking to download this file:
