eRTG3D: Empirically Informed Random Trajectory Generator in 3-D


The empirically informed random trajectory generator in three dimensions (eRTG3D) is an algorithm to generate realistic random trajectories in a 3-D space between two given fix points in space, so-called Conditional Empirical Random Walks. The trajectory generation is based on empirical distribution functions extracted from observed trajectories (training data) and thus reflects the geometrical movement characteristics of the mover. A digital elevation model (DEM), representing the Earth's surface, and a background layer of probabilities (e.g. food sources, uplift potential, waterbodies, etc.) can be used to influence the trajectories.


See the packages site on GitHub, detailed information about the algorithm in this Master’s Thesis, or test the algorithm online in the eRTG3D Simulator.
