Is Sat-Nav Destroying Local Knowledge?

Hugh Pickens writes "Joe Moran writes in the BBC News Magazine that Sat-Nav clearly suits an era in which 'map-reading may be going the way of obsolete skills like calligraphy and roof-thatching.' Sat-Nav 'speaks to our contemporary anxieties and preoccupations about the road,' writes Moran. 'More roads and better cars mean we can travel further, and so the risk of getting lost is all the greater.' But do real men use sat-nav? Moran says that men seem to recoil from being given digital instructions by a woman, and read the satnav woman's pregnant pauses, or her curt phrases like 'make a legal U-turn' and 'recalculating the route', as stubborn or bossy. Still we don't quite trust the electronic voice to get us where we want to go. 'Since before even the arrival of the car, people have worried that maps sever us from real places, render the world untouchable, reduce it to a bare outline of Cartesian lines and intersections,' writes Moran. 'Sat-nav feeds into this long-held fear that the cold-blooded modern world is destroying local knowledge, that roads no longer lead to real places but around and through them.'"

After struggling for an hour, he stepped into a big box store along the way in a small town and picked up a GPS, got there in about an hour after that.

      To be fair to you and your friend, neither of you had any local knowledge to destroy-- that's why you both needed the GPS. What was missing that we used to use was a set of turn by turn directions on paper which you could read to him over the phone when he called.

      Really, the question is silly. People who rely on GPS don't have local knowledge to destroy. In situations where they do, they ignore the GPS and use it instead. I use my GPS daily to find work sites I've never been to, but the ones I have, I spend a lot of time ignoring the GPS's instructions. "Make a left here onto the most congested street in the city", it suggests, while I retort "no, you idiot, I'm going to parallel that street on a small side street where there's no traffic". My GPS is good at reading a map, but it's a complete moron when it comes to actual local knowledge. Where the GPS shines is at giving accurate turn-by-turn directions based on your current position, which is a hell of an improvement over the kind of human generated guidance we used to have to put up with: "turn down the street with all the trees along it and turn left where the old schoolhouse used to be; when you see the big oak tree, you've gone too far".

Local knowledge trumps GPS every single time, however, because GPS devices can't make decisions based on information that isn't necessarily related to getting from point A to B. GPS can't tell you to avoid such-and-such street because it's a really rough part of town, nor can it tell you that Local Sports Team is playing a home game today at 5:00 PM, so if you drive too close to the stadium you'll be stuck in traffic for two hours. Also, from personal experience I can tell you that GPS doesn't always work accurately in places like Baltimore, MD or Washington, DC, places where the whims of urban development have created streets that are one-way during some hours of the day and two-way during others, and where a straight(ish) street will change names four times over five blocks, or where some streets are really more like paved alleys.

      I lead a motorcycle group of over 450 people. We ride our motorcycles all over the area surrounding Phoenix, Az. I personally put between 15,000 and 20,000 miles on my bike every year.

      I started to use a GPS on our trips because when you need to get 30 bikes ready for a left turn, it's nice to know it's two miles ahead instead of waiting for the sign to show up. Plus, it's really hard to read a map while you riding a motorcycle, the wind tends to move it all around unless you use a tank bag.

      I moved to Phoenix 6 years ago, and can now ride my motorcycle anywhere in this beautiful state or the Phoenix metro area without a map or GPS. The GPS and the mapping software on my PC have helped me to design routes much easier than I could have with a map. I can use Google maps to get a satellite view of roads and determine if they are dirt or not.

      These tools have helped improve my local knowledge, not lessen it.

      My wife has similar experience in her car. Her GPS has given her the confidence to go into areas in Phoenix with the knowledge that she will be able to get there safely. With that experience, she has gained a better understanding of the Phoenix area.

      The above notes, while anecdotal, indicate that for some people, the GPS helps them learn the area.

      Maybe it's all about how smart or observant the person using it is to begin with. Smart people learn faster without effort, and observant people notice their surroundings without having to work at it. I've always been good at finding my way back to a place after I've been there once or twice, even if someone else was driving. So maybe I'm just naturally more observant that those that don't learn their local area when using a GPS.

    Even in Western Europe, the digital map makers miss stuff like cycle and walking trails. If you look at a detailed map like the British Ordnance Survey, which has been built upon local knowledge for hundreds of years, you'll see an amazing amount of information that is missed in the digital maps. I was surprised the first time I looked up my local area and saw that even the tiniest woods were named, and every hill was named and had elevation data. This is local data that almost no-one cares about anymore, but it still seems a shame to lose the history.

    http://science.nasa.gov/headlines/y2008/06may_carringtonflare.htm

    In December 2005, X-rays from another solar storm disrupted satellite-to-ground communications and Global Positioning System (GPS) navigation signals for about 10 minutes. That may not sound like much, but as Lanzerotti noted, "I would not have wanted to be on a commercial airplane being guided in for a landing by GPS or on a ship being docked by GPS during that 10 minutes."

    The same article says

    On Earth, power lines and long-distance telephone cables might be affected by auroral currents, as happened in 1989. Radar, cell phone communications, and GPS receivers could be disrupted by solar radio noise. Experts who have studied the question say there is little to be done to protect satellites from a Carrington-class flare.

    Granted, recent the recent flare-related GPS disruption didn't last several days, but large flares do happen on a fairly regular basis (the article mentions 'huge' storms in 1942 and 1989). Which confirms the parent's main point: that backup tech (like sextants) is really a necessity when lives are at stake, simply on the basis of solar flares.

    Obviously, backup tech is also needed to cover everyday problems like systems breakdowns while at sea.

Oh, you can be passable and earn a decent living, but all the really good ones know exactly how the CPU is going to execute their code and how all the different parts fit together. The same thing goes for any other part of life. You can get around fine without worrying too much about how your GPS works or about the finer details of cartography, but when it comes down to it, anyone who can use a map is automatically better at navigating than someone who can't because there are going to be situations where a GPS just isn't going to be good enough, and even if you never come across those, knowing how to use a map will make you better at following directions, anyway, much like knowing how the CPU works can help you even when you're writing in a high level language.

This means that the magic voice will have incredible power in shaping urban traffic patterns. Some roads will be jammed while others will be empty, and all because of sat-nav.

    So far this year, I think all the cyclists that have been killed in London have been undertaking lorries that were turning left. Be sensible, alert and assertive and you'll be fine, even on the busy roads. The book CycleCraft has some useful guidance, but it comes down to:
    - don't undertake lorries or buses (unless they're stationary and you're sure they won't move before you get past)
    - don't ride in the gutter as cars will squeeze past and you'll hit drain covers. Ride close to where a car's left wheels travel ("secondary position"). Ride in the centre of your lane ("primary position") if you don't want cars to try and overtake, e.g. on narrow roads or approaching junctions with filter lanes.

    It's easy enough to avoid the heavy traffic by taking back streets, cycle paths and parks. I take the back streets from my flat to the South Circular (cars don't have this option, as there's a "dead end" with a gap for bikes to get through in the middle). I go along the Souch Circ for 800m, then take back streets to the Thames Path (another 2 barriers means cars don't use this route much) which gets me almost to work. It's slightly quicker to take an A road more of the way (and I sometimes do, if it's raining and the Thames Path will be muddy) but, well, people cycle along the Thames for leisure, and for the sake of one minute I can take it every day to work :-)

    Order the free TFL maps for the areas you need (link in my previous post). You can then look for a route using quieter roads, which are highlighted, along with routes through parks and along canals. For instance, the "car route" from Holborn station to Waterloo station is down Kingsway, round Aldwych then Strand, across Waterloo Bridge and around the big roundabout. Cycling, the nicer route (similar distance) is along Great Queen Street/Long Acre, down Bow Street/Wellington Street (and through the no-cars bollards), across Waterloo Bridge (in the wide bus lane), and then onto the car-free bit around the Royal Festival Hall to the station.
