High-precision geometric leveling is used to monitor the deformations of engineering structure foundations. This article investigates the impact of changing the position of the rail feet on the accuracy of digital leveling and proposes a methodology for assessing this influence. The results indicate that when the accuracy of determining the change in rail position significantly exceeds the reading accuracy, the leveling accuracy remains nearly unaffected. However, if the accuracy of determining the change in rail position is equal to the reading accuracy, the leveling accuracy decreases by 15%.
