The data set Fixed marks are divided into three groups: Stamp and country network points are determined with GNSS and are the most accurate fixed marks. Usually located at a reasonable distance from the road. Triangle points are determined by older angle and distance measurements and are therefore less accurate. They are not recommended where there are high requirements for accuracy. Triangle points are also found in areas far from the road. Many of the triangle points in the lowlands are unsuitable for GNSS measurement. The height marks are very well determined in height by precision nivellement, but the basic outline coordinates are in many cases very imprecise. Many height marks near the road have unfortunately been lost.
