Spatial representations and urban planning

• urban models - idealized representations

urbanism and digital representations

• planning and urban models

• urban models and social representation

• public space/sphere

Urbanism and Digitizationdigital city

• network, services;De Digitale Stad, 1994

• urban models


Urbanism and Digitization

large amount of data available

computers in the city x city inside the computer

a. use of virtual environments as an interface for planning activities and management

b. support and access to data and information by citizens and organizations

c. provide an infrastructure communication

d. deliver innovative services and value added information

digital city contemporary vision

“There is something new: A globe about the size of a grapefruit, a perfectly detailed rendition of Planet Earth, hanging in space at arm's length in front of his eyes. Hiro has heard about this but never seen it. It is a piece of CIC software called, simply, Earth. It is the user interface that CIC uses to keep track of every bit of spatial information that it owns - all the maps, weather data, architectural plans, and satellite surveillance stuff. ... Now it is suddenly here, free of charge”

Neal Stephenson’s (1992) novel Snow Crash

science fiction, 1992

2001 - launch of Keyhole’s Earth Viewer 2005 - launch of Google Earth

“Digital Earth” as a multi-resolution, three-dimensional representation of the planet that would make it possible to find, visualize, and

make sense of vast amounts of geo-referenced information on the physical and social

environment. Such a system would allow users to navigate through space and time, access to

historical data as well as future predictions based for example on environmental models,

and support access and use by scientists, policy-makers, and children alike

Al Gore vision, 1998


Urban Models and Social Representationgeometry X geography X demography

topographical representations fail to capture the essence of economic, political and cultural place in the contemporary city

descriptive model, if used for analysis of urban

social processes, would have to incorporate new forms of representation

Sassen, 2001


Urban Models and Social Representationareas, dwelling, adress


digital simulation of the real world

Urbanism and public space/spherephysical X virtual X real


digital simulation of the real world


virtual geographies and physical arrangements of cities



public sphere • not limited to media or public places for sociospatial interaction • the cultural/informational repository for ideas and projects Castells (2008)

• social organizations and socio-technical networks as systems and environments • spatial practices, interaction and organization that did not previously exist

Internet is not only a support element and technological mediation

• environment to information, communication and action



categories of "public", "public space" must therefore be revised


Final Remarksvirtual/digital x real/physical

Yu Zheng, Urban Computing with Taxicabs, Beijing, 2011

new tools

• display and manage flows of information• ubiquitous technologies• participatory planning, scenarios, alternatives, interactions ...


Final Remarks

• cartography as interface and infra-structure

• city as social network

• city as interface and infra-structure

Final Remarks

changes are cultural and technological

architects and urban plannersnot very present in this discussion

IT professionalsto increment the existing environment with tons of digital information

convergence between physical and digital

geographical location - interactions based on “where”

“the medium is the message”
