Unformatted text preview: n to the way in which randomness, or independence manifests itself in space. However, of far greater intrinsic interest to the geographer is discovering how non-randomness arises in point patterns by attempting to model the processes that give rise to these patterns. Figure 4 illustrates some extreme examples of non-random patterns. Patterns (a) and (b) are examples of uniform patterns; (a) depicts a triangular distribution of points, while in (b) the points are located on the corners of a square lattice. Uniform patterns are usually regarded as being diagnostic of a competitive process such that points compete for space in the plane. Thus if we imagine a uniform pattern evolving through time then the presence of a mint in plane will have the effect of lowering the probability of subsequent points being located in its immediate vicinity. A typical example of a uniform point pattern is the distribution of settlements in fairly evenly populated regions. Here there is competition between towns for market areas and consequently the settlements re...
