Question:
The process of gathering information using the sensors installed in artificial satellites is known as :
ASatellite Telemetry
BSatellite Imaging
CSatellite Remote Sensing
DSatellite Communication
Answer:
C. Satellite Remote Sensing
Explanation:
Classification of Remote Sensing based on the platform
Terrestrial Photography
The method of obtaining the earth's topography using cameras from the ground is known as terrestrial photography.
Aerial Remote Sensing
The method of obtaining photographs of the earth's surface continuously from the sky by using cameras mounted on aircrafts is known as aerial remote sensing.
Aerial remote sensing is generally used to gather information about comparatively smaller areas.
The advantage of aerial remote sensing is that information of any region can be gathered in accordance with our requirements
Another merit of this method is that contiguous pictures of the areas along the path of the air crafts are made available.
In each aerial photograph, nearly 60% of the places depicted in the adjacent photo is included.
This is done for ensuring contiguity and to obtain three dimensional vision with the help of stereoscop. This is called overlap in aerial photographs.
The instrument which is used to obtain three dimensional view from the stereo pairs is called stereoscope
Satellite Remote Sensing
The process of gathering information using the sensors installed in artificial satellites is known as satellite remote sensing
The process of collecting information using sensors fixed on artificial satellites is called satellite remote sensing.
The artificial satellites are mainly divided into two types: Geostationary satellites and Sun Synchronous satellites
