Fig. 1From: Evaluation of farm-level parameters derived from animal movements for use in risk-based surveillance programmes of cattle in SwitzerlandIllustration of a temporal network. a Three time steps (t1, t2, t3) in a schematic temporal network. In every time step, two movements between holdings take place. b the same network over the time period t1- t3. The network metrics ID, OD, ICC and OCC are calculated for every node in this network. c Table with the network metrics for every node in the temporal network. Note that paths can only be built from darker to lighter colours of the arcsBack to article page
