Elevation
The height of a geographic location above a reference point, usually mean sea level; essential for terrain analysis and modelling (standard GIS usage).
What does Elevation mean?
The vertical measurement of a place's height above or below a specified reference point—most frequently mean sea level—is known as elevation. It shows the elevation of a certain location on Earth's surface in relation to this baseline.
Because elevation aids in describing the form and characteristics of the terrain, including hills, mountains, valleys, and plains, it is an essential component of geography, mapping, and Geographic Information Systems (GIS). Applications such as flood risk assessment, infrastructure development, transit planning, environmental management, and outdoor navigation all depend on accurate elevation data. It is also crucial for comprehending ecosystem dispersion, watershed behaviour, and climatic trends. Techniques such as surveying, remote sensing, and GPS technology can be used to measure elevation.

A map that displays the height of the land surface above a reference point—typically sea level—is called an elevation map. It aids in the visualization of mountains, valleys, and slopes by representing various elevations using colours, contour lines, or shading. Geography, urban planning, environmental studies, and outdoor pursuits like hiking all make extensive use of elevation maps.
Information that shows the height of the Earth's surface or terrain above a reference point—typically sea level—is referred to as elevation data. It is frequently used to model landscapes, analyse slope, plan building projects, and assist with flood or watershed management in mapping, geographic information systems (GIS), and environmental research. LiDAR, satellite photography, GPS, and conventional surveying are some of the techniques that can be used to obtain elevation data.
A 3D depiction of a terrain's surface made from elevation data is called a Digital Elevation Model (DEM). It allows for the examination of topography, slope, drainage, and landform features by measuring the ground's height at regular intervals. DEMs are frequently used to simulate topography and aid in decision-making in GIS, hydrology, urban planning, and environmental studies.
Elevation vs. Altitude: Elevation is the height of a particular location on Earth's surface, like a city or a mountain, above mean sea level. Contrarily, altitude—which is frequently applied to flying things or airplanes—measures the height of an object or point in relation to the ground or sea level. To put it simply, altitude is the height of something above the earth or water, whereas elevation is the height of something on land.
