The Evolution of Earth Observation
The introduction of satellite technology has revolutionized the way we observe and understand Earth. Before the launch of Landsat 1 in 1972, aerial photography was the primary method for monitoring the planet's surface, which limited the breadth and frequency of observations. Landsat 1 provided high-resolution imagery, enabling scientists to track changes in land use, urban development, and natural disasters from space. This continued with advancements in subsequent Landsat missions, culminating in Landsat 9, which can now gather data in 11 different light wavelengths, providing a clearer and more comprehensive image of Earth's surface.
