The Rise of Earth Observation
Earth observation, also known as remote sensing, has come a long way since its inception in the 1960s. Initially, satellites were used primarily for military and weather forecasting purposes. However, as technology advanced and costs decreased, the field opened up to a broader range of applications, including environmental monitoring, natural resource management, and disaster response. Today, earth observation is an essential tool for governments, researchers, and industry, providing a wealth of data on the Earth’s oceans, land surfaces, atmosphere, and cryosphere.
