Abstract
This paper explores the use of light-weight national-scale spatial network models in order to develop methods of understanding urban environments in developing contexts with limited data, budgets and time availability. The validity of national-scale analysis has been established in research focussed on the United Kingdom and United States of America, but not in other socioeconomic and spatial landscapes. In order to evalute the extent to which this methodology still holds, Uruguay and The Maldives are taken as case studies. Open-source road-centre line data is used to construct spatial network models, which are analysed using space syntax analysis. First, each spatial network model is correlated with open-source population data to explore potential relationships between spatial network density (node count) and population. The study finds a notable relationship between national-scale population distribution and citywide node count, where the citywide radii of analysis is taken as the average global radii of the cities in each country under evaluation. Second, a comparative analysis of cities within each country is undertaken, finding that capital cities are consistently above the linear trendline. Potential uses of this approach in future applications are highlighted, for instance, in practical evidence-based decision making, and in research across larger samples of countries and variables. It is argued that, despite data, time and budget constraints, it is possible to construct light-weight national-scale spatial network models that are insightful in-and-of themselves, and in conjuction with other globally-available open-source data. This presents significant opportunities to equalise access to evidence-based urban design and policy.
