Endurmæling
Endurmæling is the process of repeating a measurement to verify its accuracy and reliability. In metrology and surveying, endurmæling refers to a controlled re-measurement of a quantity after an initial measurement, intended to identify drift, bias, or random error and to improve overall data quality. It is widely used in fields such as land surveying, construction, manufacturing, and environmental monitoring.
Etymology: The term combines endur-, meaning "again" or "re-", and mæling, "measurement."
Methods and workflow: Planning, instrument calibration, data collection under controlled conditions, statistical analysis of repeated measurements,
Quality and standards: Endurmæling supports traceability to international standards; measurement uncertainty is estimated in accordance with
Types: field remeasurement to check survey points; re-calibration or adjustment of instruments; cross-checks using redundant measurements.
Limitations: increases in cost and time; environmental variability; requires skilled personnel.
