The land cover of an area refers to its surface coverage, such as grasslands, housing areas, or water bodies. Changes take place in the structure of a land cover over time due to various natural environmental variables and human actions. In addition, it affects the life cycle of that region and the plans of human authorities for that piece of land. In order to detect the changes in a land cover qu...Show More
