Review:
Landsat Satellite Series
overall review score: 4.7
⭐⭐⭐⭐⭐
score is between 0 and 5
The Landsat Satellite Series is a long-running program of Earth observation satellites managed by NASA and the U.S. Geological Survey. These satellites have been capturing high-resolution multispectral imagery of the Earth's surface since 1972, providing invaluable data for environmental monitoring, land use planning, agriculture, forestry, geology, and disaster management. The series has evolved through multiple generations, with each new satellite offering improved sensors and capabilities to support scientific research and practical applications worldwide.
Key Features
