Radio 5 Live – Pod and Blogs on the Urban Tweet-o-Meter

By Media Coverage

Pods and Blogs is Radio 5 live’s programme dedicated to covering the news as seen by bloggers, podcasters and the citizen media. It is broadcast on Tuesdays at 0300 in Up All Night. Today’s episode included an interview about our Urban Tweet-o-Meter by Steven Gray, here at CASA. If you dont have access to Radio 5 then you can listen to it in their weekly podcast which should be online tomorrow via the Pods and Blogs main page. (edit – it was online early this morning and can now be listened to via the pods and blogs link…)

Next month there is an interview on BBC Radio 4 with us regarding our mapping work, as part of On the Map a series of 10 15-minute programs running Monday to Friday at 3:45 PM, beginning on March 23. We will have more details on that nearer the time…

Come in Neogeography Your Time is Up

By Digital Geography, geographic visualization, Geography, Neogeography

We are currently writing a technical report on all things geographic and coming to write the term ‘Neogeography’ has to be honest become painful. Sure, we have written many papers and book chapters on the topic but perhaps its one to lay to rest as we try to explain below…

The ability to mine data via new emerging methodologies for the collection, analysis and leverage of spatially related information is gathering pace and entering the main stream of social science. The key to this is three fold, firstly the move of information into the digital domain with datasets previously limited to corporations or local government organizations becoming available online, this is a recent trend. Secondly the rise of Neogeography, volunteered geographic information, crowd sourcing and citizen science above and beyond the traditional geographic domain. Thirdly the development of new toolkits that take advantage of various application programming interfaces (API’s) to allow non-programmers to quickly and easily mix, match and visualize datasets which would of previously been prohibitively technical. Such activites as a whole can be defined as Neogeography, the term derives from Eisnor (2006) one of the founders of www.platial.com where she defines it (Neogeography) as ‘…a diverse set of practices that operate outside, or alongside, or in a manner of, the practices of professional geographers.

Rather than making claims on scientific standards, methodologies of Neogeography tend towards intuitive, expressive, personal, absurd, and/or/ artistic, but may just be idiosyncratic applications of ‘real’ geographic techniques. This is not to say that these practices are of no use to the cartographic/geographic sciences, but they just usually do not conform the protocols of professional practice’. We see this as key to the renaissance of geographic information, the term Neogeography is perhaps of its time, in a similar manner that ‘Cyberspace’ is now rarely used. The importance is the trend towards the intuitive, expressive, personal, absurd, and/or/ artistic use of data without worrying, or indeed caring, about standards. A term to replace Neogeography? Perhaps there is not a need for one, its all about visualising spatial data, is there a need for a term that distinguishes between the professional and the non-professional, we would argue not.

Neogeography was 2006-2009, perhaps its time to leave it there.

Data Mining and Tweet-o-Meter now with Moscow, Rome, Toronto and Sydney

By data mining, Data Visualisation, Tweet-o-Meter

Our data mining tool Tweet-o-Meter now features tweet per minute within a 30km area of New York, London, Paris, Munich, San Francisco, Barcelona, Oslo, Tokyo, Toronto, Rome, Moscow and Sydney. Currently in beta and part of our wider ‘Ask’ tool it allows anyone to ‘mine’ data from Twitter or carry out a survey of either the world, a continent, a nation, a city or a local area. In short, we think it has notable potential for social science and the analysis of trends and relationships in a variety of areas.

We have run various beta tests on data collection with the main mining process starting next week over a 24 hour period. We aim to collect all tweets with a geo-location tag in the above cities, this is a large amount of data allowing various social, spatial and temporal analysis to be carried out.

The system is under development here at CASA as part of a wider survey tool as part of the NeISS project being coded by Steven Gray in association with Urban Tick, urban tick is currently carrying out analysis on the data sampled so far:


The movie below details geo-Tweets in London:

See Urban Narrative – Tracking Movement via Twitter for more information.

We will have more analysis and news of enhanced features and releases in coming posts. Data mining has huge potential to aid our understanding of the city, we are merely at the start of the process but the ability to collect every tweet within a 30km range of every major urban area on earth is certainly intriguing.

Camera Mapping and Projection: New York and Tutorials

By camera mapping, camera projection

Camera Mapping, also known as camera projection, is a quick and easy technique to apply a quick ‘3d’ look to a scene with the camera moving while minimising the amount of actual modelling. The clip below by Andrew Price of detailing a quick flight path of New York city illustrates the point:

The technique is normally used for a quick camera move where the camera stays relative or near to the nodal point of the original image, as the camera strays off center the illusion is often lost. The second movie below by Joel Wagner provides a good insight into the technique, note the last example moves slightly too far away from the original image:

Finally CGItrainer.com have a tutorial on Camera Mapping which looks at a more precise example:

When we have used the technique in the past we found it useful to look at the great tutorial over at CGarchitect on animated camera mapping, its quick and easy to do.

If this post inspires you to create a clip, do let us know…
