The article describes a method for deriving the precision of a predicted land uplift value at an arbitrary terrain point which is assumed connected in height to a levelling benchmark using GNSS and a precise geoid model. We derive a statistical model for predicting the uplift rate from the existing point rates along with its empirical signal covariance function. One of our aims is a study on how a land uplift rate model and its empirical covariance function can be determined and then used for calculating changes in height over the time interval between precise levellings or GNSS heightings.
