Referentielijn

Referentielijn is a Dutch term that translates to “reference line” or “baseline.” It denotes a fixed line used as a standard for measurement, design, and evaluation in various professional contexts. The exact meaning depends on the domain, but it generally serves as the stable point of reference against which other data, lines, or outcomes are compared.

In surveying and geodesy, the referentielijn is the primary geometric line chosen to establish horizontal or vertical datum for a project. It provides the basis from which distances, elevations, alignments and curves are measured and adjusted. The line is defined by survey control points and maintained through the project’s lifecycle to ensure consistency across maps, drawings, and measurements.

In road and railway engineering, the referentielijn defines the designed alignment of a road or track. It represents the planned geometry, from which deviations encountered in the field are recorded and assessed. This reference is essential for quality control, design verification, and contract administration.

In project management, referentielijn refers to the baseline for scope, schedule, and cost. It is the approved plan used to monitor progress and performance. Any changes typically trigger formal change control and possible re-baselining to restore a valid reference point.

Overall, the referentielijn functions as a unifying standard that supports accurate measurement, consistent design, and objective performance evaluation across disciplines where precise alignment and planning are critical.
