Figure 2From: Characterization of online groups along space, time, and social dimensionsIllustration of methods to measure dispersion of geolocated points (in red) on a map. (a) Average of pairwise geodesic distances. (b) Diagonal of the bounding box defined by the standard deviations of latitude and longitude around the center of gravity (blue cross). (c) Same as (b) but with geodesic distance of the diagonal.Back to article page
