What is Earth observation technology?
Earth observation is the gathering of information about planet Earth’s physical, chemical and biological systems via remote sensing technologies, usually involving satellites carrying imaging devices. Earth observation is used to monitor and assess the status of, and changes in, the natural and manmade environment.
Is Earth observation different from remote sensing?
Remote sensor data provide a global perspective and data about Earth for better data-informed decision-making based on the current and future state of the planet. On the other hand, Earth observation gathers information on the physical, chemical, biological, and any other related data about the planet.
What is Earth observation remote sensing?
Remote sensing is the technique of observing and analyzing objects from a distance without being in direct contact with them. When studying the Earth we often use the term Earth observation, which primarily means information collected from Earth observing satellites.
How do Earth observation satellites work?
Passive satellites detect radiation reflected off the Earth’s surface, such as visible light and infrared. In general, passive satellites are not able to work through clouds. Active satellites transmit energy towards the Earth and measure the returned signal which provides information about the Earth’s surface.
What is remote sensing technology used for?
Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers “sense” things about the Earth.

What is remote sensing technology?
What are the types of remote sensing?
There exist two main types of remote sensing classified according to the source of signal they use to explore the object, active vs. passive. Active remote sensing instruments operate with their own source of emission or light, while passive ones rely on the reflected one.
What is Earth Observation (EO)?
Earth Observation (EO) refers to the use of remote sensing technologies to monitor land, marine (seas, rivers, lakes) and atmosphere. Satellite-based EO relies on the use of satellite-mounted payloads to gather imaging data about the Earth’s characteristics.
What is the European Union Earth observation programme?
The European Union’s Earth observation programme is Copernicus. It consists of a complex set of systems that collect data from multiple sources: Earth observation satellites and in-situ sensors such as ground stations, and airborne and sea-borne sensors.
What are the applications of Earth observations?
Just as Earth observations consist of a wide variety of possible elements, they can be applied to a wide variety of possible uses. Some of the specific applications of Earth observations are: The quality and quantity of Earth observations continue to mount rapidly.
Is Earth observation becoming increasingly technologically sophisticated?
In recent years, Earth observation have become increasingly technologically sophisticated.
