dalpunktene

Dalpunktene is a term encountered in some Norwegian geographic and surveying contexts, used to describe a set of reference points along a valley profile. The name derives from the Norwegian words dal, meaning valley, and punktene, the definite plural form of points. In practice, dalpunktene function as markers or coordinates that help map and analyze the geometry of a valley, including the floor, walls, and key cross-sections.

Conceptually, dalpunktene identify critical locations within a valley for topographic mapping. Typical elements may include points on the valley floor, points at bends or constrictions, and points at notable geomorphic features along the sides. These points are often recorded with geographic coordinates and elevations, and they may be established through field surveying or derived from digital elevation models. In some uses, dalpunktene serve as control points for creating accurate cross-sections, profiles, and drainage models, as well as for planning infrastructure such as roads, tunnels, and culverts.

Applications of the concept include cartography, civil engineering, flood risk assessment, and environmental planning. In GIS workflows, dalpunktene can be integrated as a set of reference layers used to constrain valley geometry and to compare temporal changes in terrain. The exact definition and usage of dalpunktene can vary by region or project, reflecting local surveying practices and data standards.
