Jordpunkter

Jordpunkter are points associated with the Earth used as fixed references in different technical disciplines. The term is Swedish for "earth points" and is used in contexts where a stable ground reference is needed. The meaning of jordpunkter varies with discipline but shares the common idea of a well-defined point tied to the ground.

In geodesy and surveying, jordpunkter are permanent reference points or benchmarks that anchor a coordinate system, enabling accurate measurement and mapping. They are typically fixed on bedrock or durable structures, assigned precise latitude, longitude, and height coordinates, and maintained in geodetic databases. Surveying networks rely on these points to support triangulation, leveling, and monitoring of crustal movement or infrastructure alignment over time.

In electrical engineering and safety contexts, jordpunkt (singular) or its plural jordpunkter can denote grounding points—the places where circuits, equipment enclosures, and safety devices connect to earth potential. The choice and maintenance of grounding points influence fault current paths, electrical noise, and personnel safety, and must comply with national and international standards.

Because the term spans multiple fields, it is important to interpret jordpunkter from the surrounding documentation to determine whether it refers to geodetic reference points or electrical grounding points. See also geodetic datum, benchmarks, grounding, and earth reference.
