Terrain research focuses on the study of the physical characteristics of the Earth's surface, including its topography, landforms, and vegetation. This area of research examines the spatial distribution of natural features such as mountains, valleys, rivers, and forests, and seeks to understand the processes that shape and change these features over time. Terrain research is important for a variety of applications, including land use planning, environmental management, and natural resource conservation. Techniques used in terrain research include remote sensing, geographic information systems (GIS), and field surveying methods.
