Description:
A fundamental aspect of geographical research is to understand processes operating between people, objects and events through examination of their observed spatial patterns. Of prominent interest in investigating spatial processes is the scale at which they occur. Though many mathematical models have been created to explore various spatial patterns, inferring underlying spatial processes from these remains a persistent problem. This gap has often been attributed to the “scale problem” and the issue is intrinsic to all geographical research and has been an active area of inquiry for many decades. Since different processes contribute to spatial patterns at unique scales of observation, it is difficult to infer them accurately by studying patterns at any one scale alone. For example, where some processes affecting house price patterns, such as unemployment rates and income disparities, may be operational at a national or even global scale, others such as proximity to public transportation or population density may operate at the scale of local neighborhoods. Despite the importance of understanding the operational scale at which spatial processes are most effective, surprisingly few techniques exist to measure it. Consequently our understanding of spatial processes remains intuitive rather than founded in empirical evidence. Embedded in the theoretical framework of quantitative geography’s role in examining variations in patterns over space through ‘local’ forms of analysis, novel models have been developed that capture the scale of spatial processes – to, in turn, better understand the complex processes that produce the data we observe about the world.
