- get_cent_dist(movements, UTM=True)
- Get each soldier distance to the group's centroid
First step in calculating 'Stretch Index', can also use for individual's 'stretch'
Args:
movements (list): list of movement period DataFrames
UTM (bool, optional): True if using UTM data, false if GPS data. Defaults to True.
Returns:
cent_dists (list): list of DataFrames for each movement period, with centroid-distance time-series for each soldier
- get_surface_area(movements, UTM=True)
- Find the convex hull and calculate the surface area
Creates a time series of surface areas for that squad at each timepoint
Args:
movements (list): list of movement period DataFrames
UTM (bool, optional): True if using UTM data, false if GPS data. Defaults to True.
Returns:
surface_areas (list): list of surface area time-series for movement periods
- get_voronoi_areas(movements, UTM=True)
- Get the area for each soldier' voronoi space inside of the group's convex hull
Both the raw area and the ration of individual area / total area
Args:
movements (list): list of movement period DataFrames
UTM (bool, optional): True if using UTM data, false if GPS data. Defaults to True.
Raises:
ValueError: Voronoi calculation Requires 2D input
KeyError: Voronoi calculation can't handle NaN values
Returns:
voronoi_areas (list): list of voronoi area time series for each movement period
voronoi_ratios (list): list of voronoi area ratio time series for each movement period
- neighbor_dists(movements, UTM=True)
- Get distance to nearest neighbor for each soldier
Args:
movements (list): list of movement period DataFrames
UTM (bool, optional): True if using UTM data, false if GPS data. Defaults to True.
Returns:
dists (list): list of DataFrames for each movement period, with nearest neighbor distance time series for each soldier
- voronoi_finite_polygons_2d(vor, radius=None)
- Reconstruct infinite voronoi regions in a 2D diagram to finite
regions.
Parameters
----------
vor : Voronoi
Input diagram
radius : float, optional
Distance to 'points at infinity'.
Returns
-------
regions : list of tuples
Indices of vertices in each revised Voronoi regions.
vertices : list of tuples
Coordinates for revised Voronoi vertices. Same as coordinates
of input vertices, with 'points at infinity' appended to the
end.
