Remote sensing

Definition

Remote sensing is the process of collecting data about an object or area from a distance, typically using satellites or aerial sensors, to analyze and monitor environmental conditions. This technology allows researchers to gather crucial information without direct contact, making it invaluable for studying ecosystems, habitats, and changes in biodiversity over time.
