GIS and Remote Sensing plays a vital role in agricultural mapping, it proves to be useful in monitoring and management of agricultural land. By mapping geographic and geologic features of current and potential farmland more effective and efficient farming techniques are arrived at.
Agricultural site suitability using GIS analysis can be used to maximize crop yield. Weather and soil data combined with historical farming practices can be analyzed to determine what crops are best suited to plant, and how to maintain soil nutrition levels to best benefit the crops.
For vegetation health monitoring Normalized Difference Vegetation Index (NDVI) is used. This is used primarily to assess vegetation dynamics, particularly in determining the health status of crops. With NDVI, the crop chronology and their relationship with weather and climate (season) is explained.
