Remote sensing technology involves the use of satellite or aerial imagery to collect data about the Earth's surface without direct contact. This technology captures information across various wavelengths, allowing scientists to monitor changes in land use, vegetation, and climate patterns. Applications of remote sensing include environmental monitoring, urban planning, and disaster management. By analyzing the data gathered, researchers can make informed decisions and develop strategies for sustainable development. Key tools in this field include satellites, drones, and geographic information systems (GIS).
