Sažetak
Tides have largest impact on gravity measurements compared to all other environmental effects. They are a direct result of the gravitational forces of the planetary bodies, mainly the Moon and the Sun. The magnitude of tidal effects depends on the relative position of planetary bodies around the Earth and can be computed from the astronomical ephemeris. In this paper, LTide software is presented, a lightweight application for computation of the tidal gravity acceleration effects according to Longman formulas. The software solves a problem of laborious calculations and simplifies the analysis of gravity data over any time period and any surveyed area worldwide. The code is open- sourced, platform independent, written in Matlab/Octave programming language. It has graphical user interface which offers several options for import, export and visualization of the results. The software is meant to be an easy- to-use tool for geoscientists and other users in processing relative gravity measurements and tempo-spatial analysis of tidal gravity effects.
