Tweetography - New City Landscape Maps

Over the past few months we have been harvesting geospatial data from Twitter with the aim of creating a series of new city maps based on Twitter data. Via a radius of 30km around New York, London, Paris, Munich we have collated the number of Tweets and created our New City Landscape Maps. The maps created by UrbanTick are stunning, detailing the social networking landscaping.

Pictured above is London, below is New York:

UrbanTick has the full run down with New York, London, Paris and Munich, all available in glorious full screen mode via a Google Maps viewer - head over to take a look at the New City Landscapes.

Thanks got to Steven Gray who did the coding and Fabian over at Urban Tick for converting the data into maps, they are a good team.

Survey Data, Simulation and Workflows

At the moment we are locked away in a room at the University of Leeds talking about the next steps to integrate survey data, traditional data and simulation output via grid based services.

It's going to be interesting - pictured below is a first step with SurveyMapper running in MyExperiment:



Shortly you will be able to run a population reconstruction model, complete with crowd based data input with a view of gaining an insight of future transport, health and housing needs. Mixing crowd sourced data with simulation and modelling provides a new and interesting step in spatial analysis...

iPhone 3G Signal Map via Twitter

Expanding our work on gathering geographic data via Twitter Steven Gray here at CASA has created our latest version - this time showing the signal strength levels of iPhones on the 3G network around various places in the UK. The data is collected data via Twitter users using the #iPhone3GTest tag as started by Jason Bradbury from The Gadget Show on Channel 5.

The map updates every 3 minutes and a list of Tweets in icon form should go online this afternoon.

You can add to the map by tweeting the hashtag #iPhone3GTest with the first half of your postcode, your Operator, your 3G signal, and how many bars of signal you have e.g. Glasgow G12 O2 3G 5 bars and we will map your response. Remember to include your postcode or your tweet will not be shown.

Otherwise, use our handy link to post your very own signal tweet: Click here to tweet your own Signal Strength.

What is now needed is a global version, we are on the case....

The work is funded as part of the part of NeISS (National e-Infrastructure for Social Simulation) providing a platform to meet the demand for powerful simulation tools by social scientists, public and private sector policymakers.
