Vertical crustal movements in Estonia determined from precise levellings and observations of the level of Lake Peipsi [PDF]
Estonian Journal of Earth Sciences, 2016 The aim of this study was to evaluate vertical velocities of the benchmarks and their change over time based on the four precise levellings of the Estonian levelling network from 1933 to 2011, with the mean epochs being 1936.7, 1961.2, 1982.1 and 2006.9.

Precise levelling data processing near terraced landforms
Geodesy and Cartography, 2014 Precise levelling results are affected by the Earth’s gravity field, especially in areas of abrupt changes of landscape, such as terraced landforms. To eliminate the effect of the gravity field gradient, corrections need to be used in precise levelling ...
