The route master: Natural navigation

Without a satnav, Google maps or even a compass, Tristan Gooley finds his way using clues from the natural world. He shows Tim Walker how it's done

Put your iPhone back in your pocket, switch off your sat nav and stow away your A to Z. On a clear evening, Tristan Gooley can point you towards your destination (though only, he would emphasise, to within one degree) using nothing but the stars to guide him.

Gooley says he may be the world's sole living professional practitioner of an ancient discipline: natural navigation. In his new book, The Natural Navigator, he imparts the lessons that he has been teaching himself for 10 years, and has taught others, at his natural navigation school in Sussex, for the past two: how to find north by studying the puddles on a country path or the moss on a tree trunk; how to get home by following clouds, or crowds, or flocks of geese; how to use the wisdom of the Bedouin or the Pacific Islanders to make your way back to where you parked the car.

Gooley is already unique in being the only living person to have both flown and sailed solo across the Atlantic. During the trips – both completed in 2007 – he had the benefit of the best modern navigational devices.

Yet, he says, "That didn't stop me appreciating where the sun was rising, or where Orion was in the night sky. When I took off from Canada I knew I could expect the sun to rise in the north-east at that time of year, so seeing the glow over the white of Greenland was immensely comforting. I had at least six different instruments – compasses, GPS, radio navigation aids – but the thing that made the experience most exciting was feeling connected to the world beyond the cockpit window."

The author decided to turn his passions loose on the public after a conversation with a friend and fellow pilot. "He flies for British Airways, and I asked him where the sun rises. He said, 'In the east.' So I replied, 'Alright, tell me everything you know about where the sun rises.' And he said: 'I just did.' I found it strange that a professional navigator felt so removed from natural navigation. That made me feel evangelical about the subject, so I decided I had to set up the school – even if nobody came!"

Natural navigation isn't solely a rural skill, and Gooley has agreed to meet me at The Independent's headquarters in London's Kensington, to show me just how easily the art can enhance an urban walk, too. Planned, gridded cities like Milton Keynes or Canberra are tediously simple to find your way around, he explains, but London is a web of former villages, a perfect maze of misdirection for the natural navigator to overcome.

His first lesson is in finding the nearest Tube station. Especially at peak hours, the Underground breathes commuters in and out like lungs; all I need do is follow the herd.

A multidisciplinary art, natural navigation requires that I collate various different pieces of information to work out which direction I'm facing. It's a Holmesian process of deduction: clouds frequently move with the prevailing south-west wind; satellite dishes in the UK tend to point south-south-east towards the Astra satellite, which transmits Sky TV; the south-facing side of a street is likely to enjoy more direct sunlight, and therefore to have wider pavements and a higher retail presence. Kensington High Street, I confirm, runs east to west.

We move on to St Mary Abbots church at the bottom of Kensington Church Street. "The older and more dominant a building is," Gooley explains, "the more reliable a guide it is for the natural navigator." Sure enough, the building's north-facing walls – those less exposed to warm sunlight – are moss-covered and moist. Because the church was built before it could be hemmed in by the smaller buildings around it, its steeple is at the east end, as religious convention dictates.

In Hyde Park, the natural signposts become a little more, well... natural. More often than not, Gooley tells me, the south side of a tree will be bigger, with more branches curled towards the sun. A flock of geese passes overhead in formation, and he tells me that medieval monks sailed to Iceland by tracking the flight paths of migrating Brent geese. In the Pacific Islands, fishermen can follow the birds back to land at dusk. Closer to home in west London you can find the North End Road food market by the cries of the gulls that pick on its daily leftovers.

Our trek takes in a monument in Kensington Gardens to the great navigator John Hanning Speke, the first European to reach the source of the Nile at Lake Victoria. By the mid-19th century, European explorers were already slaves to their instruments; natural navigation was to them a thing of the past. Speke describes in his journal how he showed the workings of a compass to some awed local people in East Africa.

Perhaps thanks to his adventuring past, Gooley says that his natural navigation lessons are often wrongly confused with survival skills. "If you found yourself in a sticky situation, the information in the book would be very useful. But for all the times a walk ends in a survival situation, there are a million or more that turn out rather nice. That's where my interest lies. I want to enrich people's experiences, not just enable them.

"What I love about my subject is that it touches on lots of different areas, from survivalism to ancient history. One day I'll be talking to a botanist about different types of lichen, the next I'm emailing an astronomical society."

Sure enough, the book takes in Shackleton and Shakespeare, Inuits in the Arctic and Touaregs in the Libyan Sahara. "The question, 'Where am I looking?' can be answered in one word – south," he says, "or in a 5,000-word dissertation including everything from the ancient Greek astro-nomers to arboriculture."

Ideally, he says, his pupils would find themselves making good time on a walk to meet a friend, say, and duck off down an unfamiliar side street "to get that slight excitement of being a bit lost and finding your way again. You'll connect with an area in a way that you wouldn't otherwise. We all tend to repeat the same journeys over and over again; if I can help people to see their journeys in a new light, that would be great."

Gooley himself is a veteran of the scenic route. His airborne Atlantic crossing may have been brief, but his solo sailing trip took him 26 days, at the end of which he made landfall at St Lucia. Again, he was surrounded by instruments, but it was the power of nature that moved him most.

"Sometimes, during my course, I make up a pot of leaves, grass, honey, cloves and mixed spices," he says. "I get people to waft it a couple of feet below their noses. When you've been deprived of the scent of land for weeks, had only marine smells for company, and you get a waft of that rich, tropical earth – it's pretty emotional."

The future of pedestrian navigation

Written by jeff

February 28th, 2009 at 6:56 pm

Today’s pedestrian navigation relies heavily on top-down maps, and hasn’t yet made the leap to 3D point-of-view navigation like many in-car systems have. A major reason for this is that GPS+compass navigation lacks the precision needed to create a compelling experience on a handheld device. Several meters and several degrees of error creates an unpleasant jittery experience — even in-car systems occasionally make mistakes about what road you’re on — and the acceptable precision on the road is a lot lower than on foot.

So how do you build an inexpensive navigation system that is sub-meter precise, with degree-accurate heading?

Four months ago, Occipital built a system that is able to achieve this level of precision, by using standard mobile video as an auxiliary position sensor. After an approximate GPS position is established, video frames are transmitted to a server, where they are compared against a vast database of street-level imagery captured by earthmine. Each earthmine image is backed by a dense 3D point cloud. Using all of this information, we are able to estimate the user’s position within a meter, as well as three precise angles of orientation (6 degrees of freedom altogether).

Tomorrow’s pedestrian navigation won’t be top-down; it will be superimposed on the world in front of you.


Google Turn-by-turn Navigation Finds its Way to the iPhone

April 23rd, 2010 at 10:43 AM - News by Jeff Gamet

Google is bringing its own turn-by-turn navigation to the iPhone, and it won’t be charging for the feature. The Internet search giant hasn’t said when it plans to roll out its new navigation features for the iPhone, but did confirm that it’s also rolling them into its Google Maps app on the Android platform, according to MacUser.

Unlike some turn-by-turn GPS navigation apps for the iPhone that include their own built-in map sets, Google’s system will rely on an Internet connection to build and map routes to locations. Google will, however, cache the maps for a route ahead of time assuming users have an Internet connection when they enter their destination.

“Google Maps pre-caches the entire route. It needs a data connection when you ask for navigation. But while driving to your destination, if you intermittently lose the connection, it will still carry on. As long as you stay on the route,” explained Google’s Mobile Maps product manager, Steve Lee.

Google’s plans may be good news for iPhone owners that can’t afford other turn-by-turn navigation apps, but companies that already offer similar products through Apple’s App Store will no doubt be watching closely to see what impact Google’s route into their territory has.

MyFord Touch Gets Eco-Route Navigation Function To Help Curb Fuel Consumption




By Viknesh VijayenthiranEditorApril 16th, 2010

When it comes to achieving the best possible fuel mileage the way you drive can be nearly as important as the vehicle you drive. That’s why Fordhas developed a new feature for its MyFord and MyLincoln vehicle interface systems that offers an array of real-time information on fuel economy performance that can coach drivers to get more miles to the gallon and save on fuel costs.

Dubbed MyFord Touch Eco-Route, the new system works with the map-based navigation and builds on the fuel efficiency “coaching” conceptFord introduced with its SmartGauge EcoGuide display. If you don’t recall, the SmartGauge EcoGuide provides real-time fuel economy data and promotes fuel-efficient driving by showing a graphic of growing leaves and flowers.

With MyFord Touch, when a driver provides a destination to the navigation, the system accesses historical and real-time traffic data as well as posted speed information to calculate three navigation options: Fastest, Shortest and Eco-Route.

Eco-Route is not necessarily the fastest or shortest route but is the most fuel efficient. Typically, it charts a course that avoids congested freeways while maximizing the use of major roads where the driver can maintain an efficient rate of speed. Initial testing of MyFord Touch has shown fuel consumption improvements of around 15 percent.

In addition to its Eco-Route feature, MyFord Touch enables drivers to monitor and track their vehicle’s real-time fuel economy performance and mile-per-gallon averages for the past five, 10 and 30 minutes in the form of a bar chart next to the fuel gauge on the display. Drivers can customize the amount of information provided to meet their needs and hone their eco-driving skills over time.

Ford Eco-Route Navigation Option Saves Fuel On Roads Less Traveled

Friday, April 16, 2010 - by Ray Willington

Navigation still has a long ways to go in vehicles to match the value provided by standalone units. These days, an in-car nav from the factory can cost thousands, while a basic Garmin or TomTom unit will go for $100 to $300. But Ford is making strides to bring the in-car factory experience up a notch, and while Sync has done a lot to move things in the right direction, there's still a big concern around mapping and gas mileage.



Today, Ford has introduced their MyFord Touch Eco-Route feature, which is a new concept that will be implemented in many of the company's 2011 vehicles. When entering an address into the NAV system, drivers will be given three main routing options: fastest by time, shortest distance and the new Eco-Route, which is said to direct you in the way that would route you around traffic and save the most gas. It may end up taking you longer (lower speed limits) but it should save you on fuel in the long run.

MyFord Touch launches this summer on the 2011 Ford Edge and will be available globally on the 2012 Ford Focus; also, it will be standard equipment on new Lincoln vehicles beginning with the 2011 Lincoln MKX. Going green really is hitting every industry, isn't it?

  • New MyFord Touch™ driver connect technology provides an array of real-time feedback on fuel efficiency performance that helps coach drivers to optimize their miles per gallon
  • MyFord Touch map-based navigation offers an Eco-Route option, which instantly calculates the most fuel-efficient route for the driver. Ford testing shows Eco-Route can help achieve fuel economy gains of up to 15 percent
  • MyFord Touch launches this summer on the 2011 Ford Edge and will be available globally on the 2012 Ford Focus. MyLincoln Touch will be standard equipment on new Lincoln vehicles beginning with the 2011 Lincoln MKX
