Distribution of height differences between mean-tide and zero-tide systems in Poland [cm] (own study based on Mäkinen (2008))

Figure 2

Height differences ΔH between the Kronstad’60 and PL-EVRF2007-NH frames of the points of the basic reference network of Kętrzyn district along the N–S profile

Figure 3

The scheme of distribution of the points of basic reference network used for the construction of the model of height conversion from Kronstadt’60 to PL-EVRF2007-NH in the area of Kętrzyn district (height difference iso-lines are given in m)

The assessment of the accuracy of the model ΔHKronstadt′60–KRON86: raw data (the points of the reference network) and after adjustments (the Danish method)

ParameterRaw dataThe Danish method
Average [cm]–8.2–8.2
Deviation [cm]0.90.6
Maximum [cm]–6.4–6.9
Minimum [cm]–10.5–9.6
Curtosis–0.11–0.04
Skewness–0.24–0.01
