Control points
Control points and their coordinates and elevations define in practice the reference system for coordinates and elevations used in Finland.
The NLS benchmark register contains information about nationwide control points and benchmarks. The marks are mainly horizontal and elevation control points in classes 1–3 measured by the National Land Survey of Finland.
The product belongs to the open data of the National Land Survey of Finland.

- Statement
-
Earlier, the method used for determining horizontal control points was triangulation but now satellite surveying is used. The elevation control points have been determined by levelling. The dataset Control points contains points with different levels of accuracy; the information about the accuracy class is included in the control point information.

The control point data includes the coordinates (coordinate reference systems: EUREF-FIN and KKJ = the national grid coordinate system) and the elevation of the points (height systems: N2000 and N60) as well as their other attributes. The attributes include for example information of measurement method of coordinate and height values.
