Paul Longley(Professor of Geographic Information Science, UCL)

Title: Geospatial analysis of consumer data

This presentation will begin with a selective overview of the key changes in geographic information technology that have characterized the first 15 years of the 21st Century, as captured in four editions of an advanced student textbook on Geographic Information Science and Systems.


In relating the changing technological setting to our understanding of the ‘smart’ city, we will review how we are now able to measure, and hence model, human activities across a range of spatial and temporal scales. We will develop particular focus on: (a) use of sensor technologies to collect data on pedestrian movements in cities and to model flows across them; and (b) the re-use of consumer data (such as energy consumption and retail sales) to understand the relationships between work and leisure components of neighbourhood activities in smart cities.


A ‘census’ is defined as ‘an official count or survey, especially of a population’: it is comprehensive and gives shape to our understanding of what is going on in city systems, but is too costly and time consuming to be collected very often (typically every ten years). ‘Sensors’ (a close homonym) provide us with the ability to build on census data infrastructure to understand much more about what is going on in smart cities during lengthy inter censal periods. We will conclude with an assessment of the prospects for ‘smart censuses’ using consumer data.
