The Centre for Advanced Spatial Analysis (CASA) is one of the leading forces in the science of cities, generating new knowledge and insights for use in city planning, policy and design and drawing on the latest geospatial methods and ideas in computer-based visualisation and modelling. We are part of The Bartlett: UCL's global faculty of the built environment.



Oliver is a researcher and software developer at the UCL Department of Geography, where he investigates and implementing new ways to visualise spatial data, including mapping of open demographic and socioeconomic datasets, particularly London-focused ones, using OpenLayers. In the past he’s analysed educational geodemographics, UK census data and London travel flows, and created a number of popular visualisations such as CityDashboard, the Bike Share Map and the London Tube Stats Map. Formerly a financial software programmer, he studied for an MSc in GIS at City University London, and joined UCL in 2008, working at the Centre for Advanced Spatial Analysis and in Geography. In his leisure time he contributes to the OpenStreetMap project, which aims to create a free Wikipedia-style map of the whole world, as well as competing in and organising orienteering races. He blogs at and co-edits
