ERT (Environmental Remote Sensing Technology)

Environmental Remote Sensing Technology (ERT) involves collecting information about the Earth's surface and atmosphere from a distance, typically using satellites, aircraft, or drones equipped with sensors. These sensors detect reflected or emitted energy—like visible light or infrared—allowing scientists to monitor ecosystems, land use, water quality, and climate changes over large areas. ERT enables efficient, non-intrusive observation of environmental conditions, helping in disaster management, resource assessment, and conservation efforts. It provides critical data that might be difficult or impractical to gather through traditional on-the-ground methods alone.
