Remote Sensing in Agriculture and Aquaculture
Determination of a quantity by detecting it
from a distance.
A common application of remote sensing is the
use of satellite-borne instruments to determine
the location and amount of resources on the
surface of the Earth.
Management of agricultural crops and
aquacultural products is important.
Yield of crops is based on many factors like
inputs, weather, irrigation conditions, quality of pesticides and several other factors.
Optimization of inputs, yield and quality is very important.
Other methods like self diagnostics, crop scouting and pest reduction are inefficient and
result in redundant application of resources.
Remote Sensing is looked upon as the alternative.
Piloted aircraft and satellites are the primary
sources used to obtain RS images.
Satellite Imagery for Remote Sensing
Advantages
The system is reliable.
The farmer need not have special skills to
obtain and use the data .
Disadvantages
The quality and resolution of data and
imagery obtained may not be sufficient for
accurate diagnostics.
Data obtained can be easily affected by bad
weather conditions like clouds or rain.
Non availability of data “when and where”
required .The data can be obtained only at
regular intervals .
Very expensive.
