hillshadekuvat
Hillshadekuvat, often translated as hillshade images or shaded relief maps, are a type of topographic map that uses shading to depict the shape of the terrain. They are created by simulating the effect of sunlight falling on the landscape from a specific direction, usually from the northwest. Areas facing the simulated light source are illuminated, appearing lighter, while areas facing away are in shadow, appearing darker. This contrast helps to visually emphasize the undulations, slopes, and features of the land, such as mountains, valleys, and ridges.
The process of creating hillshadekuvat typically involves digital elevation models (DEMs). A DEM provides elevation data
