Invisible, Hidden, Parallel Cities: Twitter Landscapes

By revealing the social networks present within the urban environment, Invisible Cities describes a new kind of city—a city of the mind. The movie below by Christian Marc Schmidt displays geocoded activity from online services such as Twitter and Flickr, both in real-time and in aggregate. Real-time activity is represented as individual nodes that appear whenever a message or image is posted. Aggregate activity is reflected in the underlying terrain: over time, the landscape warps as data is accrued, creating hills and valleys representing areas with high and low densities of data.

In the piece, nodes are connected by narrative threads, based on themes emerging from the overlaid information. These pathways create dense meta-networks of meaning, blanketing the terrain and connecting disparate areas of the city:





Invisible Cities maps information from one realm—online social networks—to another: an immersive, three dimensional space. In doing so, the piece creates a parallel experience to the physical urban environment. The interplay between the aggregate and the real-time recreates the kind of dynamics present within the physical world, where the city is both a vessel for and a product of human activity. It is ultimately a parallel city of intersections, discovery, and memory, and a medium for experiencing the physical environment anew.

Our movie below of London's Tweets displays a similar 'hidden city':




As we posted a few weeks ago, 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 detail 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. Also thanks to Dr Chris Speed who sent in the invisible cities movie link.

Unique Animated Map Service from Viridian

The movie below by Viridian was originally created as a talking point for their own site, the animated maps proved so popular that they have now become a bespoke mapping service for clients' websites and blogs.



We kind of like it - as a small animated map in the corner of a website or on a contact page we think its a neat idea.

See http://www.viridian-online.com/ for more details.

Atlas of Cyberspace: Now Available as a Free Download

Martin Dodge and Rob Kithen's seminal book 'The Atlas of Cyberspace', is now available as a free download. The book was arguably the first mass market publication exploring the spatial and visual nature of cyberspace and its infrastructure.

It uses a user-friendly, approachable style to examine why cyberspace is being mapped and what new cartographic and visualisation techniques have been employed.

Richly illustrated with over 300 full colour images, it comprehensively catalogues 30 years worth of maps that reveal the rich and varied landscapes of cyberspace.

The book includes chapters detailing:

- mapping Internet infrastructure and traffic flows
- mapping the Web
- mapping online conversation and community
- imagining cyberspace in art, literature, and film

Martin is a CASA Alumni and as such the book captures a moment of CASA's research back in the mid 90's. Look out for the '30 Days in ActiveWorlds Map' (thats ours... :) )

YouCity New York: Stunning 3D Map of Manhattan


You City: Sample Map of Manhattan from digitalurban on Vimeo.

A while ago we posted about ShangHai WangCheng Net Tech Co., Ltd and their maps of cities in China created in a unique 'sim city esk' point of view. The company has partnered with YouCity.com to explore the western market and have just released 3 demos maps of Manhattan.

The results are stunning (see the movie above) with the final version offering multi-angle viewing and an open api promised.


You can take the samples for a spin yourself by visiting http://www.youcity.com. Such maps certainly raise the bar on what will become the norm in city mapping over the next few years.

Google Earth Thematic Mapping Engine



Every now and again a web based service comes along that takes our breath away, Bjørn Sandvik's Thematic Mapping Engine is one of those services.

Bjorn is a project manager at United Nations Association (UNA) of Norway who is currently on study leave to undertaking a master's in Geography Information Science (GIS) at University of Edinburgh. His Thematic Mapping Engine enables you to visualise global statistics on Google Earth in a way that only a few years ago would of been a showstopper using high end tools such as ESRI's ArcGlobe.

Its is quick easy with a colour scale that fits the mapping well, our movie below illustrates Global Population in 2005.



It is simple to use - go the the main page of the Thematic Engine and select a required indicator - we picked Population. You can then choose your technique of mapping - we chose Prism - and date etc. Its self explanatory with a KML provided to open in Google Earth.

For anyone interesting in mapping the Thematic Mapping Engine is well worth a look.

Mapping the Credit Crunch: Mapping the UK's Mood with Radio 4

Over the last few weeks Radio 4's PM show has been carrying out a survey on the UK's fears on the Credit Crunch. In association with our MapTube site at CASA listeners were asked for the first part of their postcode and to answer the following question:

What single factor is hurting you most about the credit crunch?

Please select one of the answers below:

Mortgage or Rent
Fuel
Food Prices
Holidays
Other
The Credit Crunch is not affecting me

We generated a new map every 30 minutes, providing an up to date view of the nations mood.


The results are fascinating, with over 22,000 responses 49% were most worried about fuel price with food running in second at 19%. The interesting part for us is to view these results both statistically and geographically as the results come in, to date the breakdown is as follows:


You can view the map at http://www.maptube.org with full details on the BBC's iPM page - of note is the rural/urban split with urban areas being notably more worried about mortgage or rent payments compared to other areas of the UK.

London Aerial Photography - 4cm Super Zoom

192.com has published the highest resolution imagery of London we have seen. Coming in at a staggering 4cm resolution the imagery is of such quality to pin point individuals and with it come privacy concerns.

The Guardian's Technology section has a full article covering these issues:
The map, from 192.com, publishes aerial photography at a resolution of 4cm for London and 12.5cm for the rest of the UK. In the right conditions, images at this resolution are enough to identify individuals - a step that existing online mapping ventures such as Google Earth and Microsoft's Virtual Earth have so far been careful to avoid.
You can read the full article here.

View the imagery direct from 192.com.maps/

* as an update - the site has great resolution but the interface and screen layout is poor - if it was in Google Maps or Live Local it would be great, as it is its a bit of a disappointment *

*you can view the maps full screen via a beta flash interface by clicking here - the extra screen space definitely helps. Thanks to eAI for the tip in our comments box, the long URL got truncated, thus our update*

Paper Maps Vs GPS with Prof Jim and his Raccoon

Following our previous post on Digital Maps: Paper Map Companies Folding we thought we would post a quick movie on the move to GPS.

Step forward Professor of RVing, Jim Twamley and his test drive of the Mio c520 GPS. We haven't a clue about the hand puppet raccoon reading his paper map but it made us smile enough to do a blog post:



Still not sure about the raccoon...

Digital Maps: Paper Map Companies Folding

Ted Roelofs of Michigan News has written a thought provoking article on the closure of Metro Graphic Arts - a traditional paper map publishing company.

Ted writes: You can still find them hanging in fire stations, city halls, schools, even floral shops: comforting, detailed, familiar guides from a fading world.

William Clifford is president of Metro Graphics Arts, which is to close next month.

The paper map.

Unfortunately for Metro Graphic Arts, of Grand Rapids, they seem to be headed the way of the buggy whip and the typewriter.

The 62-year-old company expects to close its doors by the end of February, as it sells out the last of its street guides and wall maps. Too many customers are turning to GPS devices and Internet maps, instead of what Metro Graphic offers.

You can read the full story at MLive.com. Its a sign of the times, with increasingly numbers of mobile digital devices the need for paper maps is indeed declining. Yet there is something about the paper map that a GPS or teleatlas derived system cannot match and it would be a sad day to see the demise of the paper map companies..

Google's Android - Mobile Maps, Panoramas and Google Earth?

Android the uniquely named new open source operating system for mobile phones is intriguing. We like the open source nature and the tie in with Google allows easy use of their maps application along with the ability to view linked apps such as 'Street View'.

In the video below Sergey Brin and Steve Horowitz discuss the availability of the SDK and provide a walk through of some sample applications. Of note is the 'World Time' using a spinning earth via a touch screen interface - with the link to OpenGL could this be the first glimpse of a mobile Google Earth?



The SDK and more information can be found at http://code.google.com/android/

For an interesting take on Android take a look at Robert Scoble's Google's Android Wants Developers but...

Virtual London in Second Life - Rezzing a City of 3.3 Million Buildings


As part of our GeoVue project at CASA we have the first working example of porting areas of Virtual London into Second Life.

Created around a simple North/South /East/West interface the city has been split up into sections with data loaded as and when required - in theory the whole of London could be loaded in over time.



Second Life has many restrictions on importing objects, our method ports a KML from an extruded building footprint with height attributed via LiDAR data.

The work so far is proof of concept rather than a polished model, as the movie below demonstrates:




Music by Denny Schneidemesser

Loading of sections is currently slow, this being worked upon, the next phase is to read in real-time GPS data of a pedestrian and to get the city to build around him/her while they walk...

Thanks go to Joel for writing the code.

Collaborative Maps via EditGrid

Creating your own maps via Google Maps is getting easier by the day. Using the online spreadsheet EditGrid it is possible to simply enter Longitude and Latitude alongside a placename and view the data via Google Maps.

The Spreadsheet, copied below, is 'live' and can be edited by anyone clicking this link. If you open the spreadsheet and enter your own message/placename along side Longitude and Latitude it will instantly go live to the Google Map (remember to click 'Done' in the top right hand corner after you have entered the data).



As little as a year ago the ability to collaboratively add geographical data via the Internet was a pipedream. We are now able to not only add data and tags but view them instantly anywhere in the world to street level via Google Maps.



The pace such developments are moving is astounding. Geography is suddenly back on the agenda..

Thanks for the pointer to this goes to Digital Geography, its nice to see Digital techniques being used for Geography in the Classroom.
