16 million cycle journeys across London

Programming Update

Finally getting the hard-coding of .dxf files out of Processing down... below is the density map of 500,000+ GPS points for four people in Rome that I collected last year.

GPS Maps

Update on the progress of the maps (in processing).

Worked on integrating both velocity of travel (squares) and density (circles) in combination with gps traces.

Pantheon - Different View

I've been trying to figure out how to communicate to those people who may not be familiar with the Pantheon, or its interior: the nature of the space... its proportions and configuration, and then also the path that people took while inside of it.  

 Here's a quick sketch of what I'm thinking:

Work continues on the maps of the gps traces and sketches for the thesis.  I'm hoping to defend in mid-June.

Going to see him speak on Friday in Toronto at the Goethe Institute, 5-6pm.  http://www.goethe.de/ins/ca/tor/ver/en10376198v.htm

Thanks to Nicky for this!

Pantheon and Surroundings

Finally making progress on the maps of the Pantheon as well as the other churches of Rome again, after getting the copy of the Nolli Map from the Vatican Archives scanned at 1200dpi (I'll post link to download the full-size high-res Nolli map when I get around to it).   Here's where I'm at:

Three Minute Thesis

As part of my participation in the Three Minute Thesis Competition at uWaterloo, we had to choose a single slide to represent our thesis (and present it in under 3 minutes). I decided to use one of the first plots I did of the GPS data collected from the uWaterloo Pedestrian Traffic Map study that I completed late last year. Curious to see how the event goes down tomorrow.

uWaterloo Pedestrian Traffic Map

As part of my participation on the uWaterloo New Student Services Building Project Committee, I ran a research study to collect GPS points from students on campus over a 2 week period at the end of last term.



To do this we developed, tested and launched a custom built mobile application in 3 weeks. Students downloaded the app, filling out information about themselves, such as their faculty and expected year of graduation, and then let it run the background over the study period.  By leveraging uWaterloo's social media presence  as well as via word of mouth, videos, and an informative website, we had 367 students log 382,200 GPS points, which exceeded our goal of 1% participation of the student body.

To communicate results of this study, in the form of maps of campus, I developed an interactive html5 web app (see below or visit site here) that allows users to plot the GPS data in various ways.  This tool allows stakeholders of all technical abilities to engage and use the data to make more informed decisions.

 This "map app" shows how data can be made accessible and actionable to all stakeholders. My inspiration for this was from a project my friend Matt did which allowed a client to design their own suspended ceiling (here).





I'm interested to hear any comments or suggestions!

Borges - To the Son

It was not I who begot you.  It was the dead -- 
my father, and his father, and their forebears, 
all those who through a labyrinth of loves
descend from Adam and the desert wastes
of Cain and Abel, in a dawn so ancient
it has become mythology by now, 
to arrive, blood and marrow, at this day
in the future, in which I now beget you. 
I feel their multitudes.  They are who we are, 
and you among us, you and the sons to come 
that you will beget.  The latest in the line
and in red Adam’s line.  I too am those others. 
Eternity is present in the things
of time and its imaptient happenings.

uWaterloo Pedestrian Traffic Map

Hi Everyone who goes to uWaterloo, or knows people who do:

I need your help. We are about to begin making a pedestrian traffic map of students on uWaterloo's main campus from Monday November 26 to December 7th.

Seeing how students navigate campus will allow us to make better design decisions and provide us with a valuable tool for planning the design of the new Student Services Building.

We have developed a mobile app to make participation easy. If you are a current UW student, please consider participating. There is up to $10 in compensation for the first 300 students!

If you are not a UW student please consider recommending this to someone who is.

More info: uwaterloo.ca/sso/map

* The iOS app is coming... we are waiting for Apple to put it up (US Thanksgiving).

Thanks, 

Geoff

Just a sketch... something might come out of it related to how even old, no longer extant physical artifacts effect our path...

Geno 2.0 - DNA testing

In order to understand the story my genes tell about my ancient ancestors: where they lived and when, I am participating in the Genographic Project.  While the rhetoric of the Genographic Project is hubristic and trite, the actual science behind it, as well as the implications of the data base as a whole is interesting and important.

 I am sending in my DNA samples tomorrow (from cheek swabs mailed to me) to the lab to be analysed.  Fingers crossed everything goes well... and I have the results soon.

Smart Geometry

Description:

This simulation is merging 3 things together : tangible table interface, video mapping, and particle system mimicking pedestrian flow. It's purpose is to help with quick assesment of the quality of space for pedestrian movement. This tool allows to use direct manipulation of physical objects in informing real-time simulation, thus visualising the impact of changes immediately. It might simply help to assess natural tendencies in movement of people through space, and to finetune the layout of buildings to allow spontaneous flow. Currently a prototype, still under development.. similar techniques will be used during Smart Geometry 2011 conference in 'Interacting with Cities' cluster. more info on smartgeometry.org Software : openFrameworks, Windows XP Hardware : Kinect sensor, table, DLP projector, laptop

Programming Update

Working in Processing, with java at the moment.  

Explored/attempted Voronoi Tesselation = unsuccessful. Below is someone else's script:

I've put that aside and now I'm working to implement a first two-dimensional array with identities.   The first dimension will hold location of cell (loc=x+y*i*cellsize), second will hold identity number, or the number of points occurring within a cell. 

From there I will plot the array, in the vein of a heat map:

"A heat map is a graphical representation of data where the individual values contained in a matrix are represented as colors"

Fingers crossed...

Impact Event Viz

Described by the creator, Jim Blackhurst(link) as: 

"A visualisation of the spatial clustering of death by impact in the videogame, Just Cause 2. The video is made up of over 11.3 million player death events, specifically, death by impact with terrain or objects."

His work is quite amazing: 

"A heatmap of more than 22.3 million player 'Extraction' events from Just Cause 2" -

Map of Paths in Rome -- Update

Lately I've been working on plotting and cartography.  Above is a screenshot from the map of Rome I'm making for my thesis... it  contains a figure-ground of Rome, in the vein of Nolli's famous map (http://nolli.uoregon.edu/map/index.html), and an overlay of 4 individuals GPS data over 4 months.  In the coming weeks I hope to have some more information on the GPS tracks themselves, such as an indication of the velocity.

Experiments with Super-Helices

Was messing around with the Processing script I've been making (slowly) to plot GPS points but instead of GPS Latitude-Longitude data I plotted the functions for a helix and super helix:

x =100*(COS(x)+0.5*COS(15*x)+2)
y =100*(SIN(x)+0.5*SIN(15*x)+2)

 The bottom two images had some coding problems, but they look pretty neat also:

Thanks to my brother, Alex, for his help with the equations.
