korkeusdatat

Korkeusdata, often translated as elevation data or height data, refers to information describing the vertical position of points on the Earth's surface. This data is crucial for a wide range of applications, from cartography and surveying to engineering and environmental science. It can be collected through various methods, including ground-based surveys, aerial photography, and satellite remote sensing.

The most common representation of korkeusdata is a Digital Elevation Model (DEM). A DEM is a digital representation of the terrain's topography, typically presented as a raster grid where each pixel's value corresponds to an elevation. A Digital Surface Model (DSM) is a related concept, which includes the elevation of all objects on the surface, such as buildings and trees, in addition to the bare ground.

Korkeusdata is essential for tasks such as creating topographic maps, analyzing landforms, planning infrastructure projects like roads and buildings, and modeling hydrological processes such as water flow and flood prediction. It also plays a role in understanding geological features, assessing landslide risk, and in the development of virtual environments and 3D visualizations. The accuracy and resolution of korkeusdata can vary significantly depending on the collection method and intended use.
