Bird migration analysis example

This tutorial uses data published on Movebank, specifically: Navigation experiments in lesser black-backed gulls (data from Wikelski et al. 2015)-gps.csv

This tutorial covers:

1. Trajectory data preprocessing
   • Loading movement data from common geospatial file formats
   • Exploring spatial & non-spatial data distributions
   • Converting GeoDataFrames into Trajectories describing continuous tracks of moving objects
2. Trajectory data analysis
   • Investigating individual trajectories
   • Comparing different years
   • Investigating trajectories of multiple individuals
