A spatial distribution is the arrangement of a phenomenon across the Earth's surface and a graphical display of such an arrangement is an important tool in geographical and environmental statistics. A graphical display of a spatial distribution may summarize raw data directly or may reflect the outcome of a more sophisticated data analysis. Many different aspects of a phenomenon can be shown in a single graphical display by using a suitable choice of different colors to represent differences.The information included could be where units of something are, how many units of the thing there are per units of area, and how sparsely or densely packed they are from each other.The spatial pattern of a changing landscape have some information content on the processes of land-cover change. Certain categories of land-use changes tend to fragment the landscape (e.g., expansion of smallholder farming, small-scale logging, overgrazing around deep wells). Other land-use changes increase landscape homogeneity (e.g., mechanized cultivation or ranching over large areas). There is a good correlation between remotely-sensed spatial patterns and some important characteristics of farming systems.
