elevation data
Elevation data represents the height of land or features above a reference point, usually sea level. It helps us understand the shape and relief of the Earth's surface, such as mountains, valleys, and plains. This information is used in map-making, construction, environmental management, and navigation. Elevation data is often collected through satellites, aerial surveys, or ground measurements, and is expressed in units like meters or feet. It enables detailed terrain analysis, supports geographic information systems (GIS), and aids in planning and decision-making related to land use, risk assessment, and resource management.
