Seattle Map and Borges

Interesting short video on correspondence of "map to terrain".


Simulations of events, not only disasters but also banal daily occurences (commute, lol) is likely going to grow in importance, scope, scale, as we begin to make use of the reams of data we are collecting.

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 naviga
te 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

To download app: https://play.google.com/store/search?q=uwaterloo+pedestrian&c=apps

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

Thanks, 


Geoff

Reality Games

A few examples of smartphone based games, in which you play the game within the "real" enviroment.  The games are location aware: objects, tasks, or effects are stored at locations within a city: but you can only see these objects, tasks, or effects when you have you are looking at the enviroment through your smartphone screen. The thought of people running around the city, fighting off the attack of deamons and mages which only they can see, is terrifying. 




From the article: 

The idea of playing in an area that you are intimately familiar with or to explore your city more was intriguing. While other apps use geographical location purely for reference, Shadow Cities really emphasizes your particular neighborhood and surrounding ones. After all, there is an inherent desire to defend what’s ours, and neighborhoods are a good place to start. By using actual location, the iPhone becomes a window to a parallel world, hence the name of the game.

The iPhone is a magical device that allows you to become a mage and take part in battles against mages from the other faction, of which there are two, the Animators and Architects. You discover friends on your team near your location and working together through in-game chat, you conquer your city neighborhood-by-neighborhood. There are NPCs, which are roaming spirits, and real players around you that you can fight. You fight by learning spells, which you cast my using the iPhone’s touch surface to draw the rune shape. When you are on the move, you can patrol areas for enemies.

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.

Vacuum Maglev Train

"The National Power Traction Laboratory of Southwest Jiaotong University is developing a vactrain, or a maglev train that runs through in an airless tunnel, allowing it to run at speeds of 600 kilometers to 1,000 kilometers per hour, Beijing Times reported."

From: http://www.china.org.cn/china/2010-08/02/content_20624621.htm

Also see:

Trans-Atlantic Maglev Train: 

Norway has studied neutrally buoyant tunnels (concluding that they’re feasible, though expensive), and Shanghai is running maglev trains to its airport. But supersonic speeds require another critical step: eliminating the air—and therefore air friction—from the train’s path. A vacuum would also save the tunnel from the destructive effects of a sonic boom, which, unchecked, could potentially rip the tunnel apart

...Then air would be pumped out, creating a vacuum, and alternating magnetic pulses would propel a magnetically levitated train capable of speeds up to 4,000 mph across the pond in an hour...

Photographic Timelines

A photographic technique developed by Jay Mark Johnson.  



From the site: 

"In the image, anything that is stationary is repeated throughout the sequence (that’s the horizontal lines across the image), but objects that move are only in part of the scene. Furthermore, the faster they move, the thinner they appear. In this way, a single image is capturing objects and their rate of motion through a sliver of space. The leftmost edge of the image is the furthest back in time."

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...

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.

Off to Burning Man


Yeah!!!

See below for an exerpt from the "abstract/rationale"...

My thesis/research into the paths communities take, and how these path contain historical information, will be heavily engaged by studying the ephemerality of paths/movement Black Rock City.

As the cosmologists studies singularities, so I travel to Black Rock City.

The questions I will attempt to answer are:

1.) What is the shape of the general liturgical rite within the Temple of Diana to be erected this year? I have previously mapped the shape of Catholic liturgies in 5 churches in Rome and a map of the path of people in the Temple will form an important partner to this selection.

 ^ Map of Paths in Piazza della Rotonda

2.) What is the shape of individuals during the Festival? Using a GPS receiver,  I will map 4+ individuals in a series of day-long gps mappings, collecting over 200,000 gps data points over the duration of the festival. This information will form an addition to the similar Data I have collected on Rome and Toronto.






















 ^ Map of Paths in Trastevere, Rome. 

I will be back from Burning Man around first week of September and hope to have some exciting new maps/stories/etc.

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

GPS Mapping


















Some etchings I have been working on... testing out how to do it.

Current approach:
1.) Using custom built Java script Export GPS path data as 3d DXF.
2.) Take DXF into AutoCad. Set lineweights to etch.
3.) Plot on Acrylic with 50W laser cutter.
4.) Rub acrylic paint onto etched sheet.
5.) Mount multiple mappings in wooden frame, overlayed to show similar patterns.
6.) Remove blue-plastic scratch covering.

Had alot of difficulty with dado's on frame, and also scratchs on acrylic. Generally happy with result (which will be displayed at Open Eyes Toronto 2012 on August 9th).

M1 - 7 - Catacombs of Domitilla


The Catacombs of Domitilla in Rome is an early Christian burial site in Rome.  The followings images were derived from a 1.2 billion point laser-scan of the interior: 30GB of data.



"The Domitilla Catacomb is the largest of Rome’s over 60 known catacombs, built by the early Christian communities between the late 2nd and the early 5th century. The soil around Rome consists mostly of tuff, which allows easy digging, and therefore catacombs were extended frequently and without plan. The result is a very irregular network of galleries, 15km in the case of the Domitilla Catacomb, which is challenging to document.... The documentation of the geometry of archaeological monuments, buildings, or findings by laser-scanning evolved rapidly over the last years, as scanning devices became more precise and are able to record more points in one
pass. One of the first large scan projects was the Digital Michelangelo Project, where 10 statues created by Michelangelo were digitized. The largest single data
set, the statue of David, consists of 2 Billion triangles... (Scheiblauer, et all. 2009)

M1 - 6 - Random Walk with Notes


"A man starts from a point O and walks L yards in a straight line; he then turns through any angle whatever and walks another L yards in a second straight line. He repeats this process N times."
- K. Pearson, Nature 1905.

A "random walk" is defined as a mathematical formalisation of a trajectory that consists of taking successive random steps (wiki).  


A similar concept to the "random walk" is a "stochastic process", defined as: a collection of random variables often used to represent the evolution of some random value, or system, over time (wiki).   


Physicist Leonard Mlodinow's book Drunkards Walk is about the role of chance in human endeavours.  It is an interesting and accessible read, though one which is generally resigned about things. The subtitle, "How Randomness Rules Our Lives" is illustrative of this as well as the following larger-bit: 

In the scientific study of random processes the drunkard’s walk is the archetype. In our lives it also provides an apt model, for like the granules of pollen floating in the Brownian fluid, we’re continually nudged in this direction and then that one by random events. As a result, although statistical regularities can be found in social data, the future of particular individuals is impossible to predict, and for our particular achievements, our jobs, our friends, our finances, we all owe more to chance than many people realize. On the following pages, I shall argue, furthermore, that in all except the simplest real-life endeavors unforeseeable or unpredictable forces cannot be avoided, and moreover those random forces and our reactions to them account for much of what constitutes our particular path in life. I will begin my argument by exploring an apparent contradiction to that idea: if the future is really chaotic and unpredictable, why, after events have occurred, does it often seem as if we should have been able to foresee them? (p.63)

To test out the idea I decided to actually go for a Random Walk.  


I download an app for my smartphone which claims to be random and use it to decide which direction to walk every time I come to an intersection.   

Above is the GPS track I had while conducting the random walk in the city of Rome, March 22, 2012 from 2100-2200 hours. 

Some notes taken on the random walk:

A: 
I walk four times by the door of my own house

B: 
I walk 3 times past the entrance to a restaurant in which some VIP is eating, and in front of which sits a half dozen black gleaming Mercedes with security cards milling about in front in preparation for the imminent departure. I am a security threat. 

E: 
I try with all my strength to predict which direction the stochastic process will take me: sometimes I guess right, most often times wrong, and I frustratingly walk back upon the street I have walked on 3 times before.

F: 
I walk up half the Janiculum, then am instructed to turn mid-slope and head back, walking once again on streets I had just walked: the stochastic process almost brought me to the top of a mountain.  

G:
If I wish to walk half-way up a hill and past the door of my own home 3 or 4 times moving only a few hundred meters in an hour of  continuous walking, then I should use a stochastic process to inform my daily decisions.   

The conclusion above, in Excerpt "G" is very similar to that of Karl Pearson, inventor of the "Random Walk" as formulated in a 1905 edition of Nature: "The lesson... is that in open country the most probable place to find a drunken man who is at all capable of keeping on his feet is somewhere near his starting point!"

M1 - 5 - Jeremy Woods

Jeremy Wood is a British artist who uses his path as as pencil.  He records his route with GPS to draw massive paintings across cities and landscapes.  He has worked at many different scales, exploring the possibility that are inherent in walking and paths, in a pursuit variously called “human geography”.

Jeremy Woods' bag was stolen:

My bag got stolen in a pub.  Inside the bag was a GPS receiver that I’d left switched on. 
The bag was handed in at a local police station in the early hours of the following morning. 
It was mostly emptied of valuables except for the GPS that was still recording.

From the GPS data he was able reconstruct what the bag was doing while it was stolen, with entries such as: "[21:21:09] Bag stops in Golden Square where it remains for two hours and forty minutes".  He then overlayed the GPS track onto John Snow's "Cholera Map" (the bag was apparently stolen from the John Snow pub).

“Our work is site-specific and relationship-specific. Two faces of the same coin. We either explore the nuances of our own relationship or our relationship to a location or both - a kind of looking inward and outward at the same time.” -planb



I took their work as my case study and will present one of their projects here, as well as images from another. 

The project Monday Walks, took place from June 24th to the 27th, 2010 in Leipzig and was "inspired by the demonstrations that took place in Leipzig leading up to the fall of the Berlin Wall in 1989 and beyond, the so-called Montagsdemonstrationen (Monday Demonstrations).” -planb 

The Monday Walks consisted of two parts:

1.) “a GPS animation of recreations of the journeys people took to the demonstrations in 1989. Students from the University of Leipzig interviewed people from Leipzig who had taken part in the demonstrations, and then the students reconstructed their journeys, following the specific path taken by the demonstrators. These reconstructions were recorded on GPS’s, and the journeys were then visualized”



2.) “a walk re-tracing part of the Monday Demonstrations, finishing where many of the demonstrations ended, at the Stasi headquarters, the Runde Ecke. The walk was developed in collaboration with the students and it featured original sound material from the actual time, interviews with Leipzigers who took part in the demonstrations, and some live interventions into the space and social fabric of the city”

Students were asked to interview a Leipziger who had taken part in the Monday Demonstrations in 1989, in order to reconstruct the route they took to the protest.  Their responses are documented were document a blog for any interested persons to reference:

I have taken the route of Niels Adam. Now 39, lives in Jena and operates a cinema...Many things he remembered no more, and only came with telling details, such as how he has mastered the way home without a tram. 
-Posted by tim at 02/06/2010 11:29:00 PM and translated from German.

The combination of collecting anecdotal qualitative evidence, a physical re-walking of a historical reconstructed route, and the recording of these re-walkings with GPS provides a very compelling method for documenting the path which historical events took through space, “uncovering  realities  previously unseen or unimagined, even across seemingly exhausted grounds” (James Corner. Agency of Mapping)
