Remote sensing is the acquisition of information about an object without making physical contact with the object by measuring its reflected and emitted radiation at a distance from the target area. It gives exact pictures and data on the identification of even a single tree in a large area of vegetation and wildlife. It is also helpful in the identification of biodiversity-rich or fewer areas for futuristic works on conservation and restoration of biota. It helps in the maintenances of various species including commercial crops, medicinal plants, and threatened plants.
