Land Cover
The physical material present on the earth’s surface (e.g., vegetation, water, urban infrastructure), often mapped and analysed in spatial studies (inferred from standard GIS usage).
Explain Land Cover?
The term "land cover" describes the physical elements that make up the Earth's surface, including bare soil, vegetation, water bodies, urban infrastructure, and snow and ice. It characterizes the actual land cover as seen by aerial photography, satellite imagery, or ground surveys.
Common Types of Land Cover:
Forests
Grasslands
Built-up and urban areas
Land used for agriculture
Wetlands
Bodies of water
Importance of Land Cover:
Environmental monitoring: Assists in tracking land degradation, urbanization, and deforestation.
Climate studies: Impacts water cycles, heat absorption, and carbon storage.
Planning for land use helps with conservation, disaster relief, and sustainable development.
Planning and decision-making are aided by modelling and simulation in ecological and hydrological models.
Land cover is frequently mapped using classification approaches in remote sensing and GIS to evaluate the effects of both natural and human activity on the Earth's surface and study variations over time.

Using satellite imaging, aerial photos, or drone data, land cover classification is the process of classifying the physical elements on Earth's surface, such as plant, water, urban areas, or barren soil. By offering comprehensive spatial information on the landscape, it aids in environmental monitoring, urban planning, agricultural management, and the evaluation of natural resources.
Using satellite or aerial imagery, remote sensing land cover mapping identifies and categorizes the Earth's surface features, including metropolitan areas, forests, water bodies, and agricultural land. It offers an economical and effective means of managing natural resources over wide areas, supporting urban planning, and keeping an eye on environmental changes.
The technique of examining satellite or aerial imagery over time to spot changes in the Earth's surface, such deforestation, urbanization, or agricultural development, is known as land cover change detection. This method supports sustainable land management decisions, monitors ecosystem health, and evaluates human impact for environmental scientists, urban planners, and legislators.
Land cover satellite photography helps detect and categorize features like forests, water bodies, cities, and agricultural land by providing precise information about the Earth's surface. It is extensively utilized for resource management, urban planning, environmental monitoring, and tracking ecological changes over time.
