Remote sensing is a technology used exclusively to get information about the earth. Information about an object or event is often obtained without making physical contact with this technology. This technology is used in many fields like geography, military, intelligence. Commercial, economic planning, land surveying and is completed to urge accurate information about the topics associated with the earth. Remote sensing typically uses satellite or aircraft-based sensor technologies to detect and classify objects on Earth. This includes the surface, atmosphere, and oceans supported propagated signals like an electromagnetic wave. It is often divided into 2 types "active remote sensing" and "passive remote sensing". Active remote sensing, a satellite or aircraft detects an object and its image by a sensor, while passive remote sensing detects sunlight by the sensor.
