Land cover	Description
Dense Forest	A vegetation type covered with dense growth of trees that formed nearly closed canopies rising up to 30 m
Sparse forest	Stands for woody vegetation comprised of fractional cover of scattered trees and wood lots
Cultivated land	A land area ploughed/prepared for growing rain-fed/irrigated crops, pastures and other herbaceous vegetation
