Terrænfaktorer

Terrænfaktorer, often translated as terrain factors, are variables used in various scientific and engineering disciplines to describe the characteristics of the land surface. These factors are crucial for understanding and predicting processes that occur on or are influenced by the ground. Common terrænfaktorer include slope, aspect, elevation, curvature, and roughness. Slope refers to the steepness of the land, typically measured as an angle or percentage. Aspect indicates the direction a slope faces, often expressed in degrees from north. Elevation is the height of the land above a reference point, such as sea level. Curvature describes how the slope changes over distance, with different types like profile and plan curvature. Roughness quantifies the irregularities of the land surface.

These factors are derived from digital elevation models (DEMs) and are essential inputs for a wide range of applications. In hydrology, terrænfaktorer help model water flow, erosion, and flood risk. Geologists use them to analyze landslide susceptibility and rockfall potential. Ecologists employ them to understand habitat suitability and species distribution, as sunlight exposure and water availability are directly influenced by slope and aspect. In urban planning and civil engineering, terrænfaktorer inform decisions regarding infrastructure development, transportation routes, and site selection. The specific terrænfaktorer considered and their importance can vary significantly depending on the research question or practical application.
