This document discusses various techniques for visualizing urban data to better understand cities. It describes projects like Splendor which uses crowd-sourced data, Venice Unfolding which engages local stakeholders, and LiquiData which expands the social space. The document also discusses visualizing transit patterns in Singapore, bike routes in Berlin, and metro flows in Shanghai. The overall goals of urban data visualization are represented as representing the city, raising awareness, supporting decision making, and improving daily life.

38. LIVE Singapore!
Provides people with access to a range of useful
real-time information about their city by developing
an open platform for the collection, elaboration and
distribution of real-time data that reflect urban
activity. Giving people visual and tangible access to
real-time information about their city enables them
to take their decisions more in sync with their
environment, with what is actually happening
around them.
