1 Introduction

This profiler brings together a set of urban manufacturing and urban morphology measures in the area of Greater London. Manufacturing is quantified according to 3 indicators: ‘Manufacturing Businesses’ (London Datastore), ‘Manufacturing Jobs’ (BRES) and ‘Industrial Land Designations’ (GLA). For a detailed review of these categories including the data sources see here. A cartographic summary can be consulted here.
To investigate the relationships between these measures with the spatial accesibility and urban structure of Greater London, Space Syntax measures of ‘Choice’(through-routes) and ‘Integration’(to-routes) at 2km and 10km distances are used to create 12 map overlays.

The selection of street segments with highest ‘Choice’ and ‘Integration’ (top 20%) shows a clearer view of the key street segments in each measure. A summary for these measures is shown below.

Summary of highest 20% values of Choice and Integration (n=23409)
Min. 1st Qu. Median Mean 3rd Qu. Max.
Choice 2km 14138.2 18558.2 25726.0 34227.0 40110.8 259147.2

Integration 10km 2165.3 2352.3 2558.6 2607.5 2812.8 3672.4
The differences betwween these measures is not only in their metrics but also in their spatial pattern

2 Summary matrix

The following matrix allows a visual exploratory data analysis of the measures previously presented. Each map combines a ‘Manufacturing’ with an ‘Accesibility’ data layer. The map images link to interactive maps with pan, zoom and infowindow functionalites for a deeper graphical examination.
