Remote sensing technology allows humans to analyze before deciding on action without distance limitations. Remote sensing is usually carried out to measure an object with tools that do not directly touch each other.
Remote Sensing Components
Remote sensing in its process requires several components in order to obtain maximum data. Without these components, remote sensing devices cannot work optimally. Several components of remote sensing, among others:
a. Energy source
The power source is the most important component because without a power source the remote sensing device cannot operate. The energy source in question is sunlight or other artificial energy that can produce temperature.
b. Atmosphere
The atmosphere produces several molecules such as, oxygen, carbon dioxide, hydrogen, nitrogen, and others. These molecules can affect the performance of remote sensing devices in absorbing how much of the energy source.
c. Interaction of Force and Object
The interaction of energy and objects is the interaction that occurs between energy and objects during the remote sensing process. For example, the resulting photo looks dark because when the object is monitored the reflectivity of the low power source. The interaction of energy and objects will cause the photos of each object to vary.
d. Sensors and Rides
Sensors are tools attached to the vehicle and function to detect objects and determine their location. The sensor will later produce a photo that has been determined from the distance where the monitored object is worth taking.
e. Data Acquisition
Data acquisition is a component that will show data obtained from monitoring tools. The resulting data is divided into two, namely manual data and numerical data. This data is obtained from the reflection of objects and can be used as data to continue research.
f. Data usage
The use of data is the final component that is also important in remote sensing. The use of data is when data in the form of photos obtained from monitoring is processed and used for certain purposes. This data can be used in various fields such as demography, mapping, meteorology and climatology.
Definition of Remote Sensing
Quoted from the Sampoerna Academy website, remote sensing is a technique for measuring and acquiring data from an object. Tools for data acquisition that are not in direct contact with the research object.
In addition, according to Lillesand and Kiefer, remote sensing is an art to obtain information about objects, areas or symptoms. Data analysis was carried out without direct contact with research respondents.
The art of remote sensing can be applied in the fields of environmental, natural disaster and climate monitoring. Some examples of remote sensing are ultrasound tools, weather satellites, and space tools that monitor planets from orbit.
How Remote Sensing Works
Remote sensing performs data collection by monitoring and analyzing electromagnetic radiation. Energy that is reflected and emitted on the observed object to produce a data.
Data is obtained from sensors that have recorded various wavelengths, ranging from visible light to infrared light and microwaves. When the process occurs, the energy used is sunlight.
But remote sensing can be done not only using sunlight. Along with the development of technology, remote sensing is divided into two, namely:
a. Passive Remote Sensing
Passive remote sensing is a remote sensing process that uses sunlight as the primary energy. Later, sunlight will work with remote sensing components to produce the required data.
b. Active Remote Sensing
Active remote sensing is a remote sensing process that uses artificial energy as the main energy. Examples of artificial power include pulses on radar and beams from lamps.
Benefits of Remote Sensing
Remote sensing technology has helped humans in many ways. Some of the benefits of remote sensing in its use, namely:
Helps provide an overview of how many objects are in an area. For example, such as the condition of the earth’s surface, mountains, seas, rivers, and others. Tells the conditions of an area so they can find out what the terrain is like. Provides efficiency in research because researchers don’t need to go directly to monitor an object. Provides information regarding changes in conditions from a place .
It turns out that remote sensing technology is quite close and familiar to us. A brief explanation of remote sensing above can provide knowledge regarding its functions and benefits.
