🛰️🌐Remote Sensing Components
Remote Sensing components are determined by sensing the reflected or emitted energy from the object also, processing, analyzing and applying that information for environmental applications
A - The energy source
provides the electromagnetic energy source to the target. The sources may be
from sun or manmade sensors
B – Radiation and Atmosphere -
It is the media by which the energy is transmitted to the target
C – Energy Interacts with the
target – It is depending on the target’s physical, structural, and chemical components
D – Recording Reflected Energy
by Sensor - Sensor records
the transmitted, emitted or absorbed energy by the target
E & F - Transmission, Reception and Data
generation – The
energy recorded by the sensor has been transmitted to the receiving and
processing station where the data are processed as an image
G - Data Analysis – In this stage, the images are
processed, analyzed and visualized to extract the information about object
H - Data Product and Applications – Finally, the outcome of
analyzed images is the data product and it is used for spatial decision-making
purposes
Example
1. The visible radiation
from the sun transmitted via the atmosphere that is absorbed and reflected by
objects in our earth
2. The Transmitted energy
recorded by optical remote sensing satellite, and the recorded data where
transmitted to ground station, as signals where, they are converted as image
3. The converted images are processed and analyzed than the GIS data product such as Land Use / Land Cover Map has been generated which is used for various spatial decision making
