What is remote sensing? Remote sensing is the process of gathering data about an object using tools that are not in direct contact with that object. Remote Sensing is widely used in Earth Science to study properties of the Earth such as lake or sea surface temperature, ocean color and vegetation.
Remote sensing
enables large-scale observation of areas that would be inaccessible or
otherwise difficult to access using conventional methods of data retrieval.
Remote sensing is also cost-effective and safer than collecting data in
the field. A satellite can capture
images of an area of concern in minutes that could take a researcher years
to collect in the field. The type of remote sensing
mentioned on this site deals with images collected by satellites that orbit the earth.
This data is then sent to different agencies and
organizations to be used to study the environment in question. Remote sensing
provides important information to scientists and helps us to better understand
the world around us.
