Point-Pattern Analysis & Modeling The analysis of point patterns has been important in the social, spatial, and environmental sciences for decades. Patterns of points (showing the location of phenomena) can be viewed as… geometric and space-time expressions of a geographic location theory in action . Point patterns have given researchers insights into the mechanisms, forces, and factors responsible for potentially generating the observed patterns and the drivers that affect changes in patterns over time and space.

Point pattern distributions are commonly examined and evaluated to determine whether there is regularity in the spacing or positioning of points within a defined study area…and to test whether a spatial distribution of points is “ random ” versus “ non-random ”. This can be done by using various statistical tools that either… (a) test variability in point density or point counts ( count density analyses ); or (b) examine the location, distancing, or spacing of points from nearest-neighboring points ( distance-based analyses ).

We may define “ pattern ” as an underlying characteristic of spatial arrangement which describes the location and spacing of a set of objects/occurrences/points/events in terms of … (a) “ absolute location ” – based on a mathematical coordinate system and through the point density or frequency counts per cell, areal division, or polygon); and/or (b) “ relative location ” – how objects/occurrences/points are positioned or located with respect to points which are neighboring or proximate, or with respect to the study area’s edge or border.

A “ point pattern ” is a snapshot in time – a static representation of a dynamic process ; one that potentially reveals important aspects of that process and the underlying causal factors and/or constraints that influence or give rise to the pattern. process pattern Location theory What kind of spatial pattern is formed by the arrangement of objects/points?
