movekit 0.1.22

Simple and effective tools for the analysis of movement data

MOVEKIT

movekit is an open-source software package for the processing and analysis of movement data.

movekit supports different tasks:

• Data pre-processing
  • Check data for variables required for movement analysis
  • Clean data (remove duplicates, drop missing values, etc.)
  • Use interpolation to deal with missing values in data
  • Normalize the data
  • Filter the data
  • Many more preprocessing methods
• Feature extraction:
  • Extract different features such as the distance covered, the average speed, the average acceleration, the direction or the change of direction for individual movers in between every time step
  • Apply time series analysis on these extracted features (f.e. mean and variance of speed for mover over time)
  • Check different distances (euclidean & hausdorff) in between movers for different time steps
  • Detect outliers in data
  • Examine time and duration of different phases of movement (moving and stopping) for each mover
  • Analyze environment exploration of each mover
  • Many more features can be extracted
• Group-level analysis
  • Calculate centroids and medoids of the group of movers for different time steps
  • Calculate the centroid's movement direction and compare it with individual mover's directions
  • Compute polarization of movers
  • Identify different clusters in the data by applying various clustering algorithms
  • Obtain dynamic time warping of trajectories of the different movers
  • Many more group-level features can be extracted
• Spatial data analysis:
  • Create convex hull, voronoi diagram and delaunay triangulation for all movers at each time step
  • Extract areas of the created objects
• Network analysis with networkX
  • Create network graphs created for each time step and examine their attributes (centroid, polarization, total distance, mean speed, ...)
  • Investigate individual nodes of each time steps network graph
  • Investigate individual edges of each time steps network graph
  • Track development of network graphs over time
• Plotting analysis results:
  • Create basic plots for features such as acceleration or speed
  • Plot movement of movers in static or animated images
  • Create interactive map to plot geo data

movekit provides support for movement data and trajectories in different format:

Data:

• 2-dimensional data in the Euclidean space
• 3-dimensional data in the Euclidean space
• GPS coordinates (latitude and longitude)
• Data with different time formats
• Data in (Geo)JSON format
• Data from Movebank data base
