Need for speed: An optimized gridding approach for spatially explicit disease simulations
Fig 1
Example of the regular (A) and the adaptive (B) grid construction methods applied to the UK farm population. Panel (C) shows a schematic representation of the grid-based infection transmission process. From the infectious farm i (red star) in infectious cell a, spread of infection is initially evaluated at the level of entire susceptible grid cells (b1, b2, b3) and only occasionally evaluated for the individual susceptible nodes (green).
