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.

摘要

使用广泛的新的和现有的数字数据源，可以进行空间分布分析。在使用既合适又兼容的区域单元时可能会遇到挑战。此外，区域统计数据容易产生规模效应和聚集效应，从而表现出可修改的面积单位问题（MAUP）。本文介绍了一种网络制图系统，使用户可以在区域格局的地理人口分析中尝试使用标准和定制的分区方案。在通过用户案例场景展示其价值之前，我们将描述该平台的体系结构和设计及其相关的数据处理技术。以隔离索引为例，我们演示了如何使用交互式地图可以帮助揭示索引的比例依赖性。
