Abstract: The analysis of spatial distributions is possible using a broad spectrum of new and existing digital data sources. Challenges can arise with respect to use of areal units that are both appropriate and compatible. In addition, regional statistics are prone to scale and aggregation effects that manifest the modifiable areal unit problem (MAUP). This paper introduces a web mapping system that allows users to experiment with standard and bespoke zonal schemes in the geodemographic analysis of regional patterns. We describe the architecture and design of the platform and its associated data processing techniques before demonstrating its value through user case scenarios. Using the segregation index as an example, we demonstrate how the use of interactive maps can assist in revealing the scale-dependent nature of the index. Our web mapping system can be employed to help geography students, policymakers and researchers better understand the underlying geodemographic structure of functional regions.
