What sensor was used to collect the data. Landsat and many other satellite remote sensing data is named in a way that tells you a about: When the data were collected and processed. The tier definition purpose is to support easier identification of suitable scenes for time-series pixel-level analysis, and provide temporary data that are processed immediately upon downlink to be dispensed.

Landsat Collection Tiers are the inventory structure for Level-1 data products and are based on data quality and level of processing.Landsat data have been used to monitor water quality, glacier recession, sea ice movement, invasive species encroachment, coral reef health, land use change, deforestation rates and population growth.The metadata file also contains the thermal constants needed to convert thermal band data to TOA brightness temperature Landsat Collections Level-1 data can be rescaled to top of atmosphere (TOA) reflectance and/or radiance using radiometric rescaling coefficients provided in the metadata file that is delivered with the Level-1 product.Home How to use Landsat data Using the USGS Landsat Level-1 Data Produc
