A company, ‘what3words’, established in 2013 has developed a system for communicating geographical locations with a resolution of three metres. What3words is a really simple way to talk about locations using just 3 words rather than lengthy GPS coordinates which could easily be miscommunicated. Any location can be written as ///word1.word2.word3 and the words are currently available in 37 languages with more on the way.
What3words (W3W) have divided the whole world into 57 trillion 3×3 metre squares and given each square a unique address that will never change. Many locations in the world don’t have an address in the usual format but now every small square in the world has a unique simple address that’s easy to communicate. W3W addresses are easy to say and share and are as accurate as GPS coordinates. The location of the entrance to the What3words head office in London for example is 51.520847, -0.19552100 in GPS coordinate form, or ///filled.count.soap which do you prefer?
What3words make sure that similar sounding W3W addresses are a long way apart so that if a W3W address is entered slightly incorrectly, and the result is still a valid W3W reference, the error will be immediately obvious. For example if the London address in the previous paragraph was mistakenly given as ///filled.counts.soap you will find it is in Oregon USA!
Some manufacturers such as Ford, Mercedes, Jaguar and Land Rover are adding W3W into some SatNavs for voice input. W3W is now also widely used by 80% of UK emergency services and the list is growing all the time as it’s invaluable for accurately locating those in need especially when out ‘in the middle of nowhere’ as we ralliers often are. In addition to emergency situations you may find such addresses useful for locating friends maybe on a beach or in a caravan or tent on a large site or outdoor event. Imagine trying to find a friend’s tent at somewhere like Glastonbury Festival! Now you can.
You can use W3W addresses on a computer or tablet via the Internet or on a smartphone with an iOS or Android app. With the smartphone app you need a good GPS signal, but you don’t have to have mobile data available to find your W3W address. Similarly, when out in the open the app allows you to navigate to a W3W address using the phone’s compass; the accuracy is only limited by your device.
I have added a column of W3W addresses to the printed list of all rally location coordinates which you will find on our website under the Members Area ’Rally Info/UK Rally Locations’ menu. (PDF File icon on the web page). I have also added these to the Online Rally Program web page along with the facility to view the locations on Google Maps. You cannot currently type these W3W addresses directly into Google Maps but you can enter them into the what3words app or their website for viewing and navigation. You will find much more information and examples of usage on the what3words website what3words.com in the Business and About Us sections. It’s well worth a look.
