Remote Sensing: DE

Remote sensing is the science and technology of obtaining information about objects, areas, or phenomena without making direct physical contact. It relies on sensors mounted on satellites, aircraft, or drones to detect and measure reflected or emitted electromagnetic radiation from the Earth's surface. By analyzing this data, scientists and researchers can monitor environmental changes, map land use, assess natural resources, and respond to natural disasters.Modern remote sensing began with satellite missions such as Landsat 1, which provided systematic imaging of Earth's surface. Today, advanced systems like Sentinel-2 offer high-resolution, multispectral imagery for environmental monitoring and climate studies.Remote sensing plays a crucial role in agriculture, forestry, urban planning, meteorology, oceanography, and disaster management. By providing accurate, large-scale, and timely data, it supports informed decision-making and sustainable development worldwide.
