Sat Nav Mishaps for Mobile City Blog

with 3 comments

To start things of, you can probably think of at least one satellite navigation system (sat nav) mishap. Either from your own experience, a friend’s anecdote, or from an article in the “comedy” section of your favourite newspaper. Some stories, however, are far from pleasant for the user or the environment. I wrote this post for the The Mobile City blog. It is related to my New Media MA thesis at the University of Amsterdam, for which I did a case study on “Sat Nav mishaps”, a term derived from Anthony Dunne’s reference to Mobile Mishaps in the 90s. I’ll write a more elaborate post on this subject later, as I’m still in the process of finishing the final version. I’ve also removed the draft version, which was on here for a few days as an example for the Mobile City conference. In a larger scope, the goal of the case study is to research how communication between local and global space in satellite navigation system use can be understood and, more specifically, how communication can be enabled. As we shall see, there are not just consequences for the user of the system, but also for local space and territory. The following stories show just the tip of the iceberg of Sat Nav Mishaps appearing around the globe, in repetitive fashion.

Car wrecked on railroad crossing
Paula Ceely’s story, a 20 year old student from Redditch in England, had her car wrecked after she followed her navigation system onto a railway track. Fortunately, Ceely escaped injury in the incident, otherwise the consequence of sat nav use would have been very grim. ‘I put my complete trust in the sat nav, there were no signs at all and it wasn’t lit up to warn of an oncoming train,’ Ceely told British broadcaster BBC. An article in local Welsh newspaper The Western Telegraph sparked a heated debate by locals as to whether the crossing should be made safer for drivers unfamiliar with the local. However, Paula is not unique, a similar story surfaced in the United States.

What makes Paula Ceely’s story most interesting, is that it exemplifies a locally initiated call to adjust a hazardous situation caused by sat nav. And because the mishap repeats itself, as mentioned by the locals, it tends to change existing meaning of neighbourhoods. This is not just a single case: Dutch and Belgian municipalities have filed complaints about increases in traffic moving through their residential areas.

Netherlands and Belgium: Villages file complaint against Sat Nav use

In September 2006, villages around Dutch municipality Delfzijl filed a complaint about truck drivers, mostly new to the region, using their navigation systems and causing dangerous speeding situations. On the trajectory from Nieuweschans to Delfzijl, drivers can skip fourty kilometers if they choose the shortest route algorithm. The downside is that on large parts of the trajectory the speed limit is only thirty or fifty kilometres per hour. Local Theo Nijland from the village of Woldendorp says: ‘most truck drivers usually drive eighty kilometres an hour and started to hit the breaks just before a turn’.

Sint Gilles Sat Nav

In Belgium, traffic flow through a number of villages has increased after implemention of navigation systems in traffic. In February 2007, Belgian minister of mobility Pascal Smet, in response to a complaint from the municipality of Sint-Gillis, asked nineteen municipalities around Brussels to map all conflict zones dealing with an increase in traffic due to GPS navigation. Before Sint-Gillis two other municipalities, Mortsel en Leuven, already complained about the traffic increase. Especially near schools and village centres traffic should be decreased. Similar stories have surfaced in the United Kingdom, specifically in Micklefield and Barrow Gurney.

From database error to damaging houses
The new routes not only cause a nuisance, in some cases, trucks or cars driving through villages are responsible for physically damaging the local. Villagers in English Carmarthenshire say they fear restoration work is being damaged by drivers using satellite navigation. Local residents mentioned that trucks and lorries were smashing into buildings ‘that have already had thousands of pounds spent on them’. Belgian village Meulebeke is experiencing similar damages. Because of sat nav use, heavy lorries are (illegally) driving through the center of the village. Houses have been damaged because the trucks are unable to make the turns.

Village damage Meulebeke

On a larger scale, English rail road company Network Rail blames drivers ‘following satellite navigation (satnav) instructions down narrow roads for a surge in damage to bridges and crossings.’ According to research done by the company, trucks have caused £15m-worth of damage in the past year ‘by striking low or narrow bridges after being directed under them by their in-cab systems.’

Seeking Solutions: Ignore your Sat Nav signs
Because of these mishaps, new ways are being sought the local to communicate with the user. A local space is being challenged, or tagged, by new meaning of global satellite navigation system use; the consequences of satellite navigation system use are similar all around the globe, as is evident in above stories. However, there seems to be an inability to communicate, or incompatibility, between spaces. The following solutions exemplify this. Firstly, there are calls for GIS database change by (local) politicians, for example in The Netherlands and the village of Barrow Gurney in the United Kingdom.

Secondly, and perhaps most interesting, is the appearing of new signs that constitute a level of acceptance into existing, dominant traffic protocol. Dutch village Roermond has put up signs to ask sat nav users to turn off their systems and follow an official detour (omleiding).

Roermond GPS detour

Exton, an English village, also put up a sign asking drivers to ignore their system. As local Brian Thorpe-Tracey mentions: ‘About two years ago we noticed a real increase in drivers using the lane. Vehicles are getting stuck and having to reverse back up, damaging the wall and fence. There’s even a piece of metal embedded 12ft up in a tree which looks like it’s come off a lorry.’

In a Welsh village, the first official British road signs to warn drivers about the dangers of trusting their sat nav. Especially foreign truck drivers navigating the region with their sat navs found themselves driving unsuitable roads.

Satellite navigation systems, the most widely used GPS enabled application in consumer society today, are causing interesting mishaps and perhaps even more interesting responses by local space and traffic protocol. However, solutions, such as traffic signs and calls for database change, do not enable any dialogue between global user and local inhabitant, battling over territory’s meaning. Therefore, the interesting question remaining is: how can real-time dialogue between local and user, using global technology, be established? If the sat nav algorithm would be able to take into account emotion, for example drawing its information from an Emotion Map, a vibrant dialogue might just emerge. Sat nav algorithms, the automated decision making process of navigation, is taking on existing traffic protocol. But even Sat navs are arguing what route is the best.

Google Geoday Benelux 2007 Report

with 7 comments

MarkerWhen the invitation for the Benelux Google Geoday 2007, shaped in the form of the Google Maps marker which has risen to fame in the past years, landed in my mailbox it promised to become an interesting day in Amsterdam’s EXPO XXI this Thursday. With presentations by Bernard Seefeld (Google/Endoxon), Brandon Badger (Google) and Remco Kouwenhoven (Nederkaart) in the morning and workshops on Google Earth and the Google Maps API in the afternoon. With a big thanks to the people at Generation Next who were responsible for my ticket in the first place.

Google’s Geo development (Google Earth and Google Maps) has taken a big step in the previous years, with the coming of Earth and Maps there is a definite focus on adding layer after layer of information on the globe. Like graffiti on a wall everyone can apply meanings to the maps made available by the Google Geo team. As Lev Manovich noticed in The Poetics of Augmented Space: Learning from Prada when talking about Augmented Space: The 90s were about the virtual, the 2000s will probably be about the physical. Not the infinite Internet, but the finite space of the physical land. And it seems that Google eagerly agrees with this prophecy. Below is my account of the day.

Keynote by Bernard Seefeld
Dangerous dragons were used in the early days of mapping if parts of the map were not known yet to the cartographer. This is one of the examples Seefeld uses from the early mapping practices, which stands for the improving of the image and the filling of the gaps. The early cartographers did not have the information to fill in the holes so they just drew dragons. Another example given is the map of New Holland, or what is now called Australia. The interesting thing is that the Portuguese probably reached this land first, but the Dutch were the first to draw a map of it and therefore being ‘responsible’ for the discovery of the land (a discovery from a Western perspective, anyway, as the Aboriginees were already there).

New HollandSeefeld takes the first example and also the mapping of New Holland, which was not accurate at first to say the least as the shape of the land on this image shows, to the present. He notices that the Google Geo team faces a similar situation in pasting together the best available satellite imagery to create the globe of Google Earth. Sometimes the information is available, sometimes not and in that case lesser detailed imagery has to be used. It is not about drawing dragons, but about improving satellite images.

So now we have an explanation of Google’s basemap philosophy, pasting together a globe in a way that perhaps reminds us of the patched body of Frankenstein. Building on top of that basemap is the next step and this is also the core of the Google Geo team’s stated mission: Organize the world’s geographic information and make it universally accessible and usable. Which is derived from Google’s overall mission statement, which is actually the same but doesn’t include the term geographic.

GoogleAntInstead of discovering new land, like in the age of navigation and in the second example given above, the user is now able to discover new information, the era of the information age. The emphasis here was especially on the enhanced content applied to the base like web links, reviews of places, photographs and featured content. Seefeld actually went as far as too say that the base is nice and the content makes it great. The base is always the same, just like the physical. But it is information and meanings applied to the physical space that make it what it is. The new idea is that meaning is applied with the use of the virtual, leaving aside the physical. Through the geo applications new discoveries can be done in the physical space, as an example Seefeld showed the Google ant; a species that got discovered with the help of geo applications.

But all this information applied to the surface of the Earth requires a way to search the information. This is the territory of the spatial web, which is all about geotagging, KML and more. Making the meanings applied to the Earth searchable. But nowadays discovering the earth isn’t as dangerous as it used to be. The dragons are gone; discovery has become a safe practice. Boring? Perhaps. You can always try the navigation option in Google Maps and Earth and follow the directions, even if it asks you to swim across the Atlantic Ocean.

Dragon Map

What is fascinating is the applying of so many meanings to the finite globe with the help of this virtual reality. I asked Seefeld the question what his views are on potential conflicting meanings. He emphasized the role of the user and also said that it is important to have access to all opinions. Getting everything 100% true is very difficult but the goal is to fix it again and again until it is good, with the help of user opinions. This really reminded me of the already infamous Wikipedia wars, which is more about events, persons, etc. while Google Earth is about space and meaning. As Dorling & Fairbairn say in the chapter Alternative Views from their book Mapping: Ways of Representing the World: ‘Maps have always presented pictures of ‘truth’ and just as many people have many different truths, so there are many maps to be drawn.’

“From API to mashup” by Brandon Badger
The key to presenting all these various views on planet Earth and what a website developer can show his/her visitor are mashups. Using the base map and applying content, meaning, to it. Badger emphasizes the essential role of the user and giving us a rather simple and commercial equation: Google’s tools + You = Victory. A more convincing model for the concept of the mashup was that the sum of the two parts makes for something more valuable than just the sum of the two parts: 1+1=2,53542. I guess it is a good thing Time magazine named us as persons of the year, but it also makes us a lot busier with supplying content for Web2.0 applications. When will “we” get too busy with supplying content until the point that we don’t want to do it anymore? It will probably mark the end of Web2.0: The death of the user.

Mashups by Remco Kouwenhoven
On his website Nederkaart.nl Remco Kouwenhoven shows lots of examples of mashups with the use of the Google Maps API. He showed us some of these on the screen, but the one that struck me the most was this map about the air traffic above Schiphol. What it intents to show is the high density of airplanes at Schiphol airport paired with complaints about the noise.

Schiphol Noise in Google Earth

This reminded me of a remark by Mark Monmonier in the Dorling & Fairbairn piece I already mentioned above: ‘Cartographic propaganda can be an effective intellectual weapon against an unresponsive, biased, or corrupt bureaucracy.’ These mashups can provide this cartographic propaganda in real-time. Current issues can be addressed with the help of real-time information gathering. On Kouwenhoven’s website a lot more examples can be seen and it is a definitely worth browsing and importing some of the examples into Google Earth.

The Workshops
After a morning of presentations the afternoon was reserved for us, the user, to start creating content using the tools supplied by Google as Badger pointed out. Although I’m not sure for how long these links will be online you can check out the small assignments of the workhops at these links: Google Earth workshop and Google Maps API workshop. More technical info is also available through code.google.com. There was one jawdropping example in the Google Earth workshop that I didn’t know about, which is an incredibly detailed 3D city model of Berlin. Definitely a must-see.

Hauptbahnhof Berlin 3D

After spending two hours being immersed in the representation of the physical space on the screen, the pavement on my way to the train station also had some new meaning applied to it. A strange awareness of how easy meaning can be applied to the physical space we navigate each day, or to the places where we live. Being unaware which meaning has been applied in the virtual to the places we call home. What also struck me after this day is the dependence of Google on the user, who is responsible for supplying the content. It makes you think, but for some reason I’m just feeling lucky right now.

A document in time: Anousheh Ansari’s Space Blog

with one comment

Anousheh Ansari

Not many people can say they have been a space tourist, and blogged their experiences at the same time. In the previous weeks the news has been full of Anousheh Ansari, the first female space tourist who spent 20 million dollars on a trip to space. If you want to know how the space travel was as a personal experience for her, read the blog at http://spaceblog.xprize.org/

Even though the event has passed, and the newsbuzz is not as high as it was a few weeks ago, the blog still stands out as a very interesting chronological read about the experience she had. Something that can be read for years to come. Especially “Hello World”, posted on the 21st of September, is a fascinating read. “I’m finally here…” are the famous first blogging words of Anousheh from space. It’s one small step for a (wo)man, but one giant leap for the blogosphere.

The blog as a document in time. TV and Neil Armstrong are sooo old media… or?
