Context triple: [Landsat 7, primaryInstrument, Enhanced Thematic Mapper Plus]
  • A. Operational Land Imager
    The Operational Land Imager is a multispectral imaging sensor on Landsat 8 designed to capture high-resolution, calibrated images of Earth’s land surfaces for environmental monitoring and land-use analysis.
  • B. Landsat 5
    Landsat 5 was a long-lived Earth observation satellite that provided decades of multispectral imagery for environmental monitoring and land-use analysis.
  • C. Landsat 7
    Landsat 7 is a NASA Earth observation satellite launched in 1999 that provides multispectral imagery for environmental monitoring, land use analysis, and global change research.
  • D. Landsat 4-5 TM
    Landsat 4-5 TM is a multispectral imaging instrument aboard the Landsat 4 and 5 satellites that provided medium-resolution Earth observation data widely used for land cover mapping and environmental monitoring.
