Elevation Profiles
Definition
Elevation Profiles are graphical representations showing changes in elevation along a linear path, such as a road, trail, or river. They provide a side view of the terrain and are used to analyze gradients, slopes, and elevation gain or loss.
Application
Hikers use elevation profiles to understand trail difficulty. Transportation engineers assess slope constraints for rail or road design. Hydrologists analyze riverbed gradients. GIS software generates elevation profiles by sampling elevation data along user-defined lines or routes.
FAQ
What is the purpose of elevation profiles?
To visualize terrain elevation along a path and evaluate slope and relief.
What data is required?
Digital Elevation Models (DEMs) or contour datasets.
Where are profiles used?
In trail planning, transportation engineering, and environmental assessment.
How are they created in GIS?
By sampling elevation along a path and plotting the values as a graph.
