Landsat is renowned for its comprehensive role as a series of satellites that have been capturing images of the Earth since 1972. This program, launched by NASA and the U.S. Geological Survey, is crucial for Earth observation as it provides consistent, high-quality, multi-spectral images of the Earth's surface. These images contribute significantly to various applications, including agriculture, forestry, land use planning, and monitoring environmental changes over time. The data collected by Landsat satellites offer a unique, long-term view of Earth's landscapes, enabling researchers and policymakers to make informed decisions based on historical trends and current conditions.
This understanding of Landsat's primary function solidifies its importance in the field of Geographic Information Science, where spatial data analysis and satellite imagery are vital for studying and managing natural resources and understanding environmental change.
