  • A. Landsat 8
    Landsat 8 is an Earth observation satellite in the long-running Landsat program, providing high-resolution multispectral imagery for environmental monitoring, land use analysis, and climate research.
  • B. Landsat 9
    Landsat 9 is a NASA and USGS Earth observation satellite that continues the decades-long Landsat program by collecting high-resolution multispectral imagery to monitor and study changes on the planet’s surface.
  • C. Landsat satellites
    Landsat satellites are a series of Earth-observing spacecraft that provide long-term, continuous multispectral imagery used worldwide for environmental monitoring, land-use mapping, and resource management.
  • D. Landsat 5
    Landsat 5 was a long-lived Earth observation satellite that provided decades of multispectral imagery for environmental monitoring and land-use analysis.
  • E. 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.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
