**Stamnett** and **Landsnett** points are the most accurate trigonometric points, and their use for all purposes is recommended. These are usually at a reasonable distance away from roads. Triangulation points are less accurate are not recommended where there are stringent accuracy requirements. Triangulation points can also be found in areas far away from roads. Many of the triangulation points in the lowlands are unsuitable for GNSS surveying.

The levelling bench marks are very well defined in terms of elevation by means of precision levelling, but in many cases the ground plan coordinates are very imprecise. Many bench marks close to roads have unfortunately been lost.
