%description
Creates realistic random trajectories in a 3-D space between two given fix
points, so-called conditional empirical random walks (CERWs). 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. Unterfinger M (2018). "3-D
