Carling Cup Final Tweet-o-Meter is Live

The Tweet-o-Meter developed here at CASA is now live for the Cup Final Weekend, making it, in the words of Carling, the First Digital Cup final.

The Tweet-O-Meter measures the volume of tweets about the Carling Cup Final and shows who's tweeting hardest; fans in Birmingham, Manchester or London! As Carling states - it's a great way to see where the buzz is in the build-up to, and during, the final.


For your tweets to be measured use #CCF10 and if you're following a particular team add #villa or #manutd. Also, you'll need to geolocation turned on in Twitter to do this...

To enable us to locate your Tweets, login to your Twitter account at www.twitter.com and select "Settings" at the top of the page. In the location setting, check the box next to "Enable geotagging". That’s it! Any message from now on sent via Twitter with the "#ccf10" tag will be caught by our Tweet Meters.


The Tweet-o-Meter system was developed here at CASA, University College London and measures the amount of tweets (measured in Tweets per Minute or TPM) received from various locations around the world. The gauges are updated every second giving you a live view of the TPM's in each location.


There is some serious science behind the Tweet-o-Meter, it is designed to mine data for later analysis relating to furthering our understanding of social and temporal dynamics for e-Social Science within the Twitter demographic. The system is as part of a wider survey tool as part of the NeISS project in association with us here at Digital Urban, with research by Urban Tick and coded by Steven Gray.

German and UK Truck Simulator

We can't quite remember our search terms on game engines this morning but we stumbled upon a game entitled 'German Truck Simulator'.


The game allows you to drive across a realistic depiction of Germany, visit its cities, choose from over sixty kinds of cargo, and deliver them. The game progresses by growing your truck fleet and hire the most experienced drivers to build up a business:




The game has been developed by the makers of simulations in the 18 Wheels of Steel series and authors of Euro Truck Simulator. There is quite a niche market for this type of game although the web page states that 'we are happy to confirm that the game has been released in Poland - a country where we know our games have lots of fans'.

Here is the official Polish game website: germantrucksimulator.pl.

It would be easy to put in a few jokes here and there, but in terms of simulation and visualisation this has got potential and we note there is now a UK version:




The UK version was relased last week, ever had a craving to drive the motorways of the UK and chose between over sixty kinds of cargo to deliver? Head over to http://www.uktrucksimulator.com/ for full details.

The the 1-hour trail demo version of the UK game is not available until April 19th, 2010 but you can download the German version now.

Do let us know how you get on if you do, happy trucking.

Carling Cup Final using Tweet-o-Meter

Part of our remit for e-Science here at CASA and du is to use our research in new and innovative ways to get it out into the field. Indeed thats what the blog is all about, sharing our work and the science/techniques behind it. As such this weekend Carling Carling is positioning this weekend's Carling Cup Final as the "first digital cup final" and is asking fans to take part in the biggest-ever live Twitter commentary during the game using our Tweet-o-Meter.


The Molson Coors lager brand is aiming to get fans talking about the game, which sees Aston Villa take on Manchester United, on the social networking site by using the hash tag #CCF10 and submitting their comments to @thecarlingcup.

The sponsor will track the levels of activity across the social media platform as well as the topics supporters are discussing around the game via a new Tweet-o-Meter, which the brewer has created in partnership with us here at the Centre for Advanced Spatial Analysis, part of the University College London.

Carling brand director, Martin Coyle, says: “Our ambition is always to give fans a bigger voice and get them involved with the competition every step of the way - the great thing about digital activity is that it gives everyone the opportunity to have their say in what should be a superb occasion.

“With all the activity we’ve got lined up on Sunday we genuinely believe that this is the first ever digital cup final. It should be a cracking game and if our activity can add a little more to the overall experience then it’ll be a great way to celebrate 50 years of the competition.”

Your be able to view the results via our customised Tweet-o-Meter over the weekend on Sky Sports and online, we will put a link up as soon as its ready.

In the meantime our city Tweet-o-Meter continues to 'mine' the cities for social trends...

Tutorial: Photoshop Image Stacking for Day Trails

Creating star trails is a well known technique in Astrophotography and the same technique can be used to create trails of activity during the day. The results are both unique and potentially useful to identify heavily used routes or flows in urban areas.

You will need:

1 x Timelapse System, you can use a simple webcam as per our previous Tutorial: Torch + Webcam = HD Timelapse System a DSLR such as the Canon G9 with CHDK , a iPhone with the free  Gorrilacam app or any camera that can take photos at regular intervals.

1 x Copy of Photoshop, you can download a 30 day trial.

1 x Photoshop Stacking Action (thanks to Deep Space Astrophotography)

Time Taken, 2 Hours (including capture and processing).

Setting Up

The concept is simple, set up your camera, webcam or iphone at a suitable location, and capture an image at regular intervals, for our example we captured an image every 2 seconds pointing down at a London street:


We left the camera running for an hour capturing 1800 images, saved into a folder on our computer.

The next step is to open photoshop and start stacking the images.

Image Stacking in Photoshop

The images will be stacked onto of an intially blank image via a simple automated action:

1) Create a new blank black image the same size are your captured photographs.

2) Load the action into the action windows in Photoshop and load the action Startrails.atn.


3)  In Photoshop click 'File', 'Automate' and 'Batch'. Select the action you have just loaded and choose your directory with the images as source and make sure you select 'None' for the output directory.

Click 'Ok' and leave it running, our Mac laptop took around an hour to stack the images - resulting in the 'Day Trail' below:


You can clearly see the path of the traffic and the most utilised sections of the walkways over the hour, we simply like the effect.

We have created a Day Trail pool on Flickr if you create a stacked image feel free to add it to the pool...

Relief: Physical 3D Interactive Maps: A Step Towards the X-Men GI

Relief is an actuated tabletop display, which is able to render and animate three-dimensional shapes with a malleable surface. It allows users to experience and form digital models like geographical terrain in an intuitive manner.


The tabletop surface is actuated by an array of 120 motorized pins, which are controlled with a platform built upon open-source hardware and software tools. Each pin can be addressed individually and senses user input like pulling and pushing as the clip below illustrates:


TEI 2010 / Relief: a responsive 3D surface from benny on Vimeo.

The system is termed a "scalable actuated shape display", created by Daniel Leithinger, Adam Kumpf, and Hiroshi Ishii of MIT's Tangible Media Group. In the chat about this around the office it was suggested was that it reminds us of the maps used in the X-Men films, now that would be a neat way to display data.

Please Rob Me.com - GeoTwitter Shows Empty Houses (To Rob).

We have been working on something behind the scenes recently that brings up all sort of issues of privacy, our worries pale into insignificance however compared to the twisted genius that is http://pleaserobme.com/




The site uses terms such as 'left home', compared to your profile to work out your not around, it then links to a map showing where your now empty home is (assuming you live on your own). Genius, as is the sites discaimer 'Our intention is not, and never has been, to have people burglarized.'

See http://pleaserobme.com/ for full details and a list of opportunities for those so inclined...

Architectural Cinematography - Rooftops: Paris

The movie below entitled 'Rooftops' was created as a tribute to Georges Eugène Haussmann (1809-1891), who was behind the beautiful architecture of Paris. Taken by Mister K Cartoon with a Canon ixus 200is/Canon sd 980 using Colorista, Magic Bullet Looks, After Effects & Movie Maker for post production it portays the style and architecture of the city wondrously:

Lumitectura: Light, Music and Architecture

Lumitectura is a music video by barno about the relation of light, music and architecture. The clip is defined by 3 elements.

-One videofile, shot between 2 and 6 pm.
-The speed of playback of this file, which is synchronised manually to the music.
-Approximately 50 different masks, which define where the underlayed movie is going to appear on the screen. This makes it possible to have multiple light situations in the same moment.

The concept is expertly executed:

The sunlight caught from the building is the "natural" palette for the entire colors of the clip and its up there with some of our favorites here on du.

Metropolis: City Animation made entirely from Images Printed on Paper

We are late to the table on this one but its so good that we thought it would be madness not to post about it. Metropolis by Rob Carter is a quirky and very abridged narrative history of the city of Charlotte, North Carolina. It uses stop motion video animation to physically manipulate aerial still images of the city (both real and fictional), creating a landscape in constant motion.

Starting around 1755 on a Native American trading path, the viewer is presented with the building of the first house in Charlotte. From there we see the town develop through the historic dismissal of the English, to the prosperity made by the discovery of gold and the subsequent roots of the building of the multitude of churches that the city is famous for. Now the landscape turns white with cotton, and the modern city is ‘born’, with a more detailed re-creation of the economic boom and surprising architectural transformation that has occurred in the past 20 years:

Metropolis by Rob Carter - Last 3 minutes from Rob Carter on Vimeo.



Charlotte is one of the fastest growing cities in the country, primarily due to the continuing influx of the banking community, resulting in an unusually fast architectural and population expansion that shows no sign of faltering despite the current economic climate. However, this new downtown Metropolis is therefore subject to the whim of the market and the interest of the giant corporations that choose to do business there.

Made entirely from images printed on paper, the animation literally represents this sped up urban planners dream, but suggests the frailty of that dream, however concrete it may feel on the ground today. Ultimately the video continues the city development into an imagined hubristic future, of more and more skyscrapers and sports arenas and into a bleak environmental future. It is an extreme representation of the already serious water shortages that face many expanding American cities today; but this is less a warning, as much as a statement of our paper thin significance no matter how many monuments of steel, glass and concrete we build.


In short its fantastic... see http://www.robcarter.net/ for more of his work.

Timelapse on the iPhone: A look at the free Gorillacam App

Joby, the people behind the Gorillapods, have released a free camera app for the
iPhone entitled 'Gorillacam'. Of note the application features a timelapse mode allowing multiple photos spaced at various intervals, ranging from 1 second apart, up to 2 minutes. We have run a few tests and with a first generation iPhone 10 seconds is the most reliable time frame to chose due to the time taken to save an image, second and third generation seem to cope with faster times. That said, 10 seconds is nigh-on-perfect for timelapses and the application does a sterling job.

We set the application running on an overcast winters day and the output of 1600x1200 jpgs is more than enough to output a 720p (HD) movie to YouTube with room for some post processing pan movement:



Music is courtesy of the rather good unsigned band - Lemonade Joe.
The movie was made simply by opening QuickTime Pro 7 and selecting 'image sequence' with the pan added via After Effects. The iPhone camera is never going to win awards but for a quick timelapse then Gorillacam is a must have for any iphone user, especially at the price, ie free.

Timelapse: Making the Map

Whether it is making a map of a city or a map of a local tourist attraction, as is the case below, there is a high level of expertise involved and it is mesmerising to see the process as a timelapse.

John Potter was recently contracted by the tourist attraction, Flamingo Gardens, in Davie, Florida to redesign their visitor's map. He decided to record the project via an on going screen capture:

Adobe Illustrator Time-Lapse Video from John Potter on Vimeo.

The style reminds us in some ways of 'Transport Tycoon' and that can only be a good thing. Read more about the project at escapekeygraphics.com/entry/118/Adobe_Illustrator_Time-Lapse_V/ and see more of John's work at escapekeygraphics.com

Restoring Historic Jeddah

'squint/opera’s' film for the redevelopment of Jeddah Central District describes a project of six million square metres, the largest city centre project in the Arab world. The narrative explains the historical importance of the city and makes the case for a sympathetic development, aiming to revitalise the city’s architectural and social inheritance whilst protecting its utterly unique character.

The style is typically refreshing (once you get past the vertical bars...)

Restoring Historic Jeddah - English Version from squintopera on Vimeo.



Archive photographs and pictorial representations of the city animated by subtly shifting two-dimensional planes give way to a long, and thoroughly impossible, tracking shot in which the viewer’s gaze seems to be the cause of a spectacular regeneration: dilapidated buildings are renovated, roads healed, trees and shades descend to provide comfort in public spaces. We have featured squint/opera many times here on du, their in-house style makes it good to have such companies around...

City Tweet Meter: Adds Graphs, Dials, London ahead of New York

Our Tweet-o-Meter which keeps track of tweets per minute within a 30km area of New York, London, Paris, Munich, San Francisco, Barcelona, Oslo, Tokyo, Toronto, Rome, Moscow and Sydney, now features graphs. We are currently running dynamic graphs for each city over the last hour with 24 hour graphs online next week. The results are interesting, London is just ahead of with New York on number of tweets with Oslo, Rome and Sydney in the lower ranks.


Currently in beta, the meter is part of our wider 'Ask' tool which will 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, currently carrying out analysis on the data sampled so far.

We are moving it into the 'real world' as well with a series of Tweet-o-Meters linked to panel meters sitting on our shelves here in CASA:

Bing Streetside: Flickr in 3D Space, 3D Transitions and Notable Potential

Microsoft have just just rolled out a new application that is currently in a tech preview phase that pulls photos from Flickr®, associates them with Bing Maps Streetside photos and then overlays them by stretching the photo to form fit where in the world it belongs. The new application called Streetside Photos is currently available in Seattle, San Francisco and Vancouver (Canada) to view your Flickr photos in a whole new way. We gave it a spin this morning and captured the video below, it has huge potential to view historic photos and crowd source the latest imagery.

Note how the 3D transitions between scenes and how the photos become part of the panorama:

Steam Punk Beta Tweet-O-Meter

As regular readers will know our Tweet-o-Meter features tweets per minute within a 30km area of New York, London, Paris, Munich, San Francisco, Barcelona, Oslo, Tokyo, Toronto, Rome, Moscow and Sydney.

Ben Blundell, here at CASA, has taken some time off from our TOTeM project and has hooked up a series of panel meters to the script via a custom arduino module. The result is a suitably 'steam punk' version of Tweets per minute in New York, London and Paris. We would of hooked up Munich but ran out of meters:

Analog Tweet-O-Meter from Benjamin Blundell on Vimeo.


All it needs now is a brass case and an 'on/off' handle...

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.

See http://www.casa.ucl.ac.uk/tom/ to view the Tweet-o-Meter, we should have some early analysis soon and graphs for the cities within the next day or so.
For those too young or perhaps simply nostalgic for the late 70's/early 80's hit that inspired the work, here is PopMusik via YouTube (its great...).

Thanks go to Ben and Steven for their work on this - see Bens http://www.section9.co.uk/, and Stevens http://stevenjamesgray.com/ for more info on their work both inside and outside of CASA time. Thanks also go to Russ Garrett (russ.garrett.co.uk/) and the London Hackspace for help with the code.

Writing: OmmWriter - Write those Posts/Papers Quicker...

A post of a slightly different flavour this morning (bare with us), as recently we have been churning out the words for various papers/reports and it got us thinking. Writing, as i think we all know, can be hard at times and the cold yet cluttered look of many word processing packages can make writing the latest scientific paper a laborious process. After all if you have a wide screen monitor and a browser with your word processor of choice side by side, it is only two clicks away from facebook, twitter, YouTube or any google search in the name of research. As such i thought i would write a quick post about OmmWriter, a new kind of word processor that somehow takes away the distractions, presenting a full screen experience without any icons or clutter in sight. In fact the only thing i can see at the moment, as i type, is a winter scene and a tree lost in mist at the bottom right of the screen – such is the interface.



While your typing OmmWriter also plays gentle calming music, its all very new age and to be honest something we would normally run a mile from. Its certainly a long way from the ethos that is all things digital and urban.

Yet, there is something strangely compelling about the whole experience, sure it cant help with the content but for anyone wishing to find a new way to write i heartily recommend taking a look at OmmWriter. It is available free of charge, currently only for the Mac but a windows version seems to be in the works. If they could just put an image of the city in the distance...

Google Buzz Layer on Google Maps: The InfoCrowd

Google has just announced 'Google Buzz' a social networking tool similar in some ways to Twitter but with location brought to the forefront. You can quickly add your location to your 'buzz' and its viewable on a map. Of note is the 'buzz layer' in the new Google Maps app that allows you to see whats going on in a location via the local information provided by the users using buzz - the InfoCrowd:



Interesting and big enough to cause an upset in the current social networking scene, also powerful enough to change the way we view information about the city.

Fotografic Memories: Memories, Music and Timelapse

Photographer Salman Ashrafi notes that in today's world, depending on what we do, we rarely find the time to just sit and observe everything that goes on around us. His movies, known as 'Fotografic Memories' represent Salmans' work to make up for this loss of time and we really like his technique of combining frames with timelapse and music as the first example below of Toronto demonstrates:

Downtown Toronto from Fotografic Memory on Vimeo.



The technique and concept can be adapted to any situation - below is the 'memory' of a bus ride in London comprised of 738 photographs:

BUS RIDE from Fotografic Memory on Vimeo.



Finally, Building and Clouds - Dubai:

Extracts of Local Distance: A Unique Take on Architectural Photography

Countless fragments of existing architectural photography are merged into multi-layered shapes. The resulting collages introduce a third abstract point of view next to the original ones of architect and photographer - this is the concept behind Extracts of Local Distance.

Digital scans of analogue architectural photography form tiny pieces of a large resulting puzzle. The original pictures are being analysed and categorised according to their vanishing-points and shapes. Based on this analysis, slices are being extracted from the source image. These slices retain the information of their position corresponding to their original vanishing-point and thus form a large pool of pieces, ready to be applied to new perspectives and shapes.

The clip below provides a look at the process:


Extracts of Local Distance from STOESELTNTPRO on Vimeo.


Using the extracted image segments, it is now possible to form collages of originally different pictures with a new common perspective. In order to compose a collage, a perspective-grid is defined and a lining of matching image segments is being applied. The segments are not altered to match the frame but fitting ones are chosen from the sheer mass of possible pieces. By defining additional keywords which describe the content of the original photographs, the selection of segments used for the final composition can be influenced. Thus a contextual layer is added through the semantic linking with the source material.


The recompositions mix and match the views and perspectives of both the architect and the photographer with a third, newly chosen frame. The resulting fine-art prints are entirely unique, and represent a new take on architectural imagery.

Head over to http://www.localdistance.org/ for full details, especially the results page which has some stunning images.

Skopje 2014 Visualisation

The clip below details a visualisation of municipality of Skopje (Macedonia) in 2014.

The St. Konstantin and Elena church and Alexa nder the Great monument are part of the Skopje 2014 project which envisages the transformation of the central district of the city:



The visualisation is in stark contrast to the most of the renders and animations we feature here on du and in many ways that is a good thing, indeed by the end of the clip with the rousing music we were quite getting into it. That said, we cant comment on the soundness of the plan - take a look at Macedonia: Online Rebellion Against “Skopje 2014″ Plan for full details on the reaction so far.

Processing: A 3D City in One Minute

We have featured the students work as part of the The Master of Advanced Studies in CAAD at ETH in Zurich quite a lot recently and we are quite fastidious as to what goes on the blog. It goes to show the quality of the output.


The following example by Jakob Przybylo, Min-Chieh Chen and Michele Leidi is a typical - this time creating a city using processing:


Processing City - Sandy City (Trailer) from mjchen on Vimeo.


The clip below provides an insight into the process:


Processing City - Sandy City (HD version) from mjchen on Vimeo.



Being able to create a city in one minute - using their processing application is impressive, it also allows output via .dxf, as such it can be imported into any number of rendering/modelling packages.

No word yet on a wider release, but it would be good to see if this could be made available....

Paper: Mapping for the Masses Accessing Web 2.0 Through Crowdsourcing

Continuing the publication online via Issuu of our papers we include our recent paper written with Andrew Crooks, Michael Batty, and Richard Milton from CASA entitled "Mapping for the Masses Accessing Web 2.0 Through Crowdsourcing" as published in Social Science Computer Review.

"The authors describe how we are harnessing the power of web 2.0 technologies to create new approaches to collecting, mapping, and sharing geocoded data. The authors begin with GMapCreator that lets users fashion new maps using Google Maps as a base. Click the right arrow to turn the page:


The authors then describe MapTube that enables users to archive maps and demonstrate how it can be used in a variety of contexts to share map information, to put existing maps into a form that can be shared, and to create new maps from the bottom-up using a combination of crowdcasting, crowdsourcing, and traditional broadcasting. The authors conclude by arguing that such tools are helping to define a neogeography that is essentially ‘‘mapping for the masses,’’ while noting that there are many issues of quality, accuracy, copyright, and trust that will influence the impact of these tools on map-based communication."

Keywords:
network economies; neogeography; web-based services; map mashups; crowdsourcing; crowdcasting; online GIS.

Google Earth - Creating a Zoom Movie

A quick post as few years ago we wrote a tutorial on creating a 'zoom' movie from Google Earth, it involved all sort of issues with paths and local caches and reversing frames. Nowadays its simply a case of 'right clicking' in Google Earth and dragging the mouse:

Google Earth Zoom from digitalurban on Vimeo.



Google Earth fixes on the location (in our case the CASA offices) so you can drag back and forwards for a smooth zoom in/out. The movie was recorded using Snapz Pro on a Mac but any screen recording tool would do. Its nice to know that this is so much simpler now, although slightly worrying that i almost take a digital earth zooming out and back in at high resolution within 15 seconds for granted...

GIS and Augmented Reality in 2015

The last 12 months has seen a turning point in terms of bringing geographically aware augmented reality to mobile devices. Significant developments in locational technology such as the inclusion of a built-in digital compass, GPS (Global Positioning System) and accelerometers into mobile phones have allowed not only location but also heading, and pitch to be detected and therefore incorporated into data display systems. These built-in technologies have brought augmented reality to the hands of the masses, and the phones themselves have sparked a market driven boom in fusing augmented reality with location-based services (LBS).Currently applications are in their infancy and mainly focused on specific topics such as ‘show me where the closest x is’. This however represents the tip of the iceberg with the addition of a GIS into the mix there is notable potential for the industry.

The short paper below was written by Sung-Hyun Jang of the GIS and AR blog and us here at digital urban as part of a larger wide ranging technical report for the Association of Geographic Information which is coming out soon. You can read the short below via Issuu:

30 Days in ActiveWorlds: Community, Design and Terrorism in a Virtual World.

30 Days in ActiveWorlds was a project aimed at documenting the development of a virtual environment from the beginning to end, the point where a plot of virgin land would develop into a community with a urban layout.

In the days long before Second Life it provided an early look at life, love, architecture and the threats of Armageddon from a terrorist group in a virtual world. It remains one of our favorite pieces of work to date:

The Renaissance of Geographic Information: Neogeography, Gaming and Second Life

Web 2.0, specifically The Cloud, GeoWeb and Wikitecture are revolutionising the way in which we present, share and analyse geographic data. In this paper we outline and provide working examples a suite of tools which are detailed below, aimed at developing new applications of GIS and related technologies. GeoVUE is one of seven nodes in the National Centre for e-Social Science whose mission it is to develop web-based technologies for the social and geographical sciences. The Node, based at the Centre for Advanced Spatial Analysis, University College London has developed a suite of free software allowing quick and easy visualisation of geographic data in systems such as Google Maps, Google Earth, Crysis and Second Life.

We are trying out the service by Issuu to share and view our documents online, if it works well then the digital urban booklet will go online next week (click the right button to turn the page):




These tools address two issues, firstly that spatial data is still inherently difficult to share and visualise for the non-GIS trained academic or professional and secondly that a geographic data social network has the potential to dramatically open up data sources for both the public and professional geographer. With our applications of GMap Creator, and MapTube to name but two, we detail ways to intelligently visualise and share spatial data. This paper concludes with detailing usage and outreach as well as an insight into how such tools are already providing a significant impact to the outreach of geographic information.

A Day in the City

Produced by Danny Bull the movie below uses ambient sound in place of dialogue or narration, this non-verbal portrait crosses language barriers and gives insight to the culture that is Downtown Miami:

A Day in the City from Danny Bull on Vimeo.

Although not the kind of movie we normally feature here in du, it grabbed us sufficiently to makes us think that perhaps we need to include more photographic/film based work.

The Attractive City Generator

The 'Attractive City Generator' is an an interactive installation by Sofia Georgakopoulou, Edyta Augustynowicz and Setafnie Sixt. It was created as part of the The Master of Advanced Studies in CAAD at ETH in Zurich. The students task was to explore urban design methodologies with the use of parametric programs based on object oriented programing, with their particular area of interest focosed on interactivity in urban planning. The video below is extremely impressive, indeed it raises the bar for student projects:




We featured some other work from the course earlier in the week, detailing a 3D City based on Conway's Game of Life, with this quality of output compared to other courses we have seen ETH is up there with some of the best.

Tech/Geo Buzz Words Early 2010 - Rising and Falling Terms and Phrases

At the moment we are mid-writing with various, papers, technical reports and book chapters all seemingly with the deadline of next week. As such and while looking back through previous papers and grants we have identified the 10 phases and buzz words that are either on the rise or on their way down.


Buzz Words on the up...

GeoCloud - geographic data and visualisation tools via cloud computing, we used it in a paper last year and it still feels timely.

Digital Recursion - the activity of representing and accessing digital media which is nested in some form within computer networks. A phrase by Mike Batty, again in a joint paper from last year (see our publications page), he has a tendency to come up with catchy terms.

Web 3.0 - although annoying to many after the over use of Web 2.0, Web 3.0 is arguably read/write/execute with the operating system and the web being one and the same.

Volunteered Geographic Information (VGI) - is the harnessing of tools to create, assemble, and disseminate geographic data provided voluntarily by individuals (Goodchild, 2007). Not a new term by any means but still a good one to use in any paper or grant involving geographic information. Indeed its one of the those phases you wish you had come up with yourself.


Steady

Mirror Worlds - representations of the real world in scaled down simplified form that were originally pictured as working in parallel to the reality itself but with strong interaction both ways between reality and it mirror. The term was first popularized by David Gerlernter.

Social Shaping - although not a new term by any means it crops up a lot in papers and grant applications at the moment. In short the term can be linked back to MacKenzie and Wajcman's 1985 publication 'The Social Shaping of Technology' where they state that the characteristics of a society play a major part in deciding which technologies are adopted.

With the rise of browser technologies the concepts behind social shaping provide an interesting take on which tech comes to the forefront and we would argue their ever shortening lifespan.


Buzz words on the way down...

Digital - technology that uses discrete (discontinuous) values. By contrast, non-digital (or analog) systems use a continuous range of values to represent information. Slightly worrying as that's the name of the blog, it just feels a bit 90's...

Neogeography - a diverse set of practices that operate outside, or alongside, or in a manner of, the practices of professional geographers. As we mentioned in a previous post, that was 2006-2009, its time to move on.

Far Down -

The Grid - increasingly being replaced in papers by mentioning Web Based Services, which it could be argued can also be seen as The Cloud. The Oxford e-Science Centre define The Grids as:
The name that describes the next significant development in Internet computing. A term first coined in the mid '90s to describe a vision for a distributed computing infrastructure for advanced science projects, the Grid was first properly explained by Ian Foster and Carl Kesselman in their book The Grid: Blueprint for a New Computing Infrastructure.
The Grid is currently lost in the trough of disillusionment and all those hours sat at conferences talking about it feel a bit wasted.

Web 2.0 - the term Web 2.0 has been around since 2004 and is still at the forefront of many academic discussions on the future of technology. Coming about as the result of a discussion between Tim O'Reilly and Dale Dougherty on the status of the web, Tim puts forward a list from 2004 which puts the term into context:

Web 1.0
Web 2.0
DoubleClick --> Google AdSense
Ofoto --> Flickr
Akamai --> BitTorrent
mp3.com --> Napster
Britannica Online --> Wikipedia
personal websites --> blogging
evite --> upcoming.org and EVDB
domain name speculation --> search engine optimization
page views --> cost per click
screen scraping --> web services
publishing --> participation
content management systems --> wikis
directories (taxonomy) --> tagging ("folksonomy")
stickiness --> syndication

Wikipedia notes that Web 2.0 refers to a perceived second generation of web-based communities and hosted services — such as social-networking sites, wikis and folksonomies — which aim to facilitate collaboration and sharing between users. Web 3.0 is nipping at its heals as a new dawn of read/write/execute leaves Web 2.0 behind.

This post should perhaps be filed under 'ways to write anything but that tricky bit in the paper that's due next week'...

Noticings : The Game of Noticing the World Around You

This is a nice concept - taking photos of things you 'notice' and uploading them to flickr with the tag 'noticings' and a geolocation. Noticings are interesting things that you stumble across when out and about.



In short, Noticings is basically a game about learning to look at the world around you, as their site states - Cities are wonderful places, and everybody finds different things in them. Some of us like to take pictures of interesting, unusual, or beautiful things we see, but many of use are moving so fast through the urban landscape we don't take in the things around us.

You need a camera, and a way of recording where a photo was taken. That might be adding it by hand to the image within Flickr, or it might be a GPS. The ideal device to play Noticings is a camera with GPS built-in, such as the camera on a Smartphone like an iPhone or Android device.

Head over to http://noticin.gs/ to take part, we like it a lot!

Thanks to Ben over at Section 9 for sending this in.

Make a 3D Paper City

Sometimes its good not to be digital - the movie below, expertly made by brusspup, shows how to build a 3D city out of paper:



Best of all, you can download the template here: http://img442.imageshack.us...

Voxopolis: 3D City via Conway's Game of Life

Build a 3D city using the rules from Conway's Game of Life and you've got our attention. The movie below details such a 3D city engine based developed in Processing by Jeannette Kuo, Dino Rossi and Dominik Zausinger:



The team seem to come from the
The Master of Advanced Studies in CAAD at ETH in Zurich - a one-year postgraduate program with a focus on computer-based architectural design and its automated production. The program examines the use of current information technologies as an augmentation of concepts of architecture.

Very neat...

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

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

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

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:
