Global Urban Constellations

Geographers have long grappled with the complex and ever changing configurations of global urbanism. Many terms have been coined to describe new 20th and 21st century urban forms: conurbations (Geddes, 1915), multi-nuclei cities (Harris & Ultman, 1945), megalopolis (Gottman, 1961), world cities (Hall, 1966), desakota (McGee, 1991),  fractal cities (Batty & Longley, 1994), network cities (Batten, 1995), … Continue reading Global Urban Constellations

World Population Density Interactive Map

A brilliant new dataset produced by the European Commission was recently released- the Global Human Settlement Layer (GHSL). This is the first time that detailed and comprehensive population density and built-up area for the world has been available as open data. As usual, my first thought was to make an interactive map, now online at- http://luminocity3d.org/WorldPopDen/ … Continue reading World Population Density Interactive Map

Open Source Public Transport Accessibility Modelling

The RGS-IBG annual conference has been on this week, and I presented as part of a series of geocomputation sessions arranged in advance of the 21st anniversary Geocomputation conference in Leeds next year. The topic was current CASA research from the RESOLUTION project, looking at developing fast and consistent methods of measuring public transport accessibility between different … Continue reading Open Source Public Transport Accessibility Modelling

Environment & Planning Featured Graphic: World City Populations Time-Series Map

The World City Populations Interactive Map is now available as a static map, and has been published as a Featured Graphic in Environment and Planning A. The EPA article includes details on the UN World Urbanization Prospects data, and the methods used to create the map. For a high resolution version of the static map, click below-

Mapping the Global Urban Transformation

One of the best datasets for understanding the explosive growth of cities across the world in the last 75 years in the UN World Urbanisation Prospects research, which records individual city populations from 1950 to 2014, and includes predicted populations up to 2030. I have been meaning to create an interactive map of this fascinating data for…

ESRI Urban Observatory- the right model for city crowdsourcing?

This month ESRI made an interesting move into the field of global city data with the launch of Urban Observatory (TM). The site has some great interactive visualisation ideas with simultaneous mapping of three interchangeable cities, linked navigation and indicator selection. It provides an intuitive interface to explore the diverse forms of world cities- Furthermore this … Continue reading

World City Living and Working Densities: Poles Apart?

One of the most recognisable visualisation techniques used by LSE Cities in the Urban Age publications is the 3D density map- an intuitive and engaging way to represent built form, and enable comparison of very different city environments across the globe. I’ve been producing 3D density maps in my own research for around five years … Continue reading

Urban Age Electric City Conference

I recently began a new job at LSE Cities and have been working for the last month on materials for the Electric City conference in London, taking place on the 6th and 7th December this week. The conference will be exploring smart cities and disruptive urban tech from a sociological slant, and includes talks from … Continue reading

Copenhagen and Hong Kong: Mapping Global Leaders in Green Transport

Cities that achieve social and economic success without high car use generally have three things in common: high densities, good urban design, and successful planning frameworks that integrate land-use with public transport, walking and cycling networks. I’ve been working on an LSE Cities project that investigated two leading global cities in green transport- Copenhagen and … Continue reading
