Hi Michael

From reading the web site, as I understand it, they have chosen the words from 
a big dictionary file.  The interesting points were that they deliberately 
choose smaller words for built up areas, going to larger words elsewhere on 
landmass and the biggest words out to sea.   This was to make the most likely 
to be used combinations shorter and more memorable.  They also filtered out all 
the rude words.   They have also taken the trouble to ensure that similar 
groups of words are no where near each other.  If you try hovering over the map 
and looking at each square the words from one square to the next are quite 
different. If you go to their map and type in two or two and a half words till 
the suggestions come up you will see that similar suggestions (maybe one ends 
in a plural) are nowhere near each other to make typos obvious.  Another 
feature is that different languages are not just translations of the base 
English, in case words are longer or more easily confused on the other 
languages.   I haven't seen what grid the system is based on ,though i presume 
standard 1984 Sat nav.

Why?  Will their main aim was to give accurate easy mapping to places without 
road names or post codes.  Even our post codes are only accurate to 100 m or so 
but the situation is worse in less developed places. If you live in an over 
crowded place you can still give an accurate address really easily.   If your 
delivery driver was using free open source map from Navmii (sp?) , formerly 
Open Street Map he should be able to find you to 3m. It's free mapping on your 
phone that understands w3w.   Also the web site streetmap.co uk does.
This is their target market.  They don't expect you to radio the coast guard 
with your coordinates in this format!

It's more accurate than a post code , and easy to remember compared to lat and 
long to the same accuracy.

Merry Christmas

Two things that I ask someone to explain:

1. How does the 3-word position-designation work? Aside from the names of the 
positions, what is the co-ordinate system? Latitude & longitude? How are the 3 
words chosen for each of the 3 meter by 3-meter locations?

2. What's wrong with latitude & longitude?

...or, if preferred, some widely-used plane-coordinate system?

Hi Doug

If you haven't been concentrating I added the W3W address to my signature a few 
months back.

Given the 3 m resolution you actually get a few choices of what address to pick 
for any given plot of land.   frog.happy.froze is actually more my living room 
than front door.   I wandered the cursor around till I found the most memorable 
three words

At the moment if you want to navigate by W3W the NavMii free mobile sat nav app 
(using OpenStreetMap data) understands the addresses.


in the descriptions says   "Local Place search (powered by TripAdvisor, 
Foursquare and What3Words)"

The other site that uses them is 
www.streetmap.co.uk<http://www.streetmap.co.uk>.    For those of us dial 
recorders who want to have a location converted to multiple formats as easily 
as possible the "Click here to convert coordinates" under the maps is 
invaluable, and includes the W3W reference on the last line   see 
http://www.streetmap.co.uk/idgc.srf?x=538955&y=177217 for example

I have been told of another method called what3words.com<http://what3words.com>

Designed in 2013 and developed since then, it uses a grid of the world made up 
of 57 trillion squares of 3 metres by 3 metres. Each square has been given a 
3-word address. what3words has named the 17 trillion squares on land with 3 
words in 10 other languages in addition to English. Of potential value to less 
developed countries.  My contact says:  "A very good idea I think as it is 
easier than numbers and covers the whole globe (dependent of course on the w3w 
database continuing to exist, which let's hope it does) to give e.g. addresses 
in African shanty towns or remote villages in India as well as where there are 

An intriguing system, based on the fact that three words, however unrelated, 
are rather more memorable than a latitude/longitude. Typing Greenwich 
Observatory comes up with oval.blast.improving. My house has a similar unique 
set of words.

Well worth a look.

Sundiallers like to give precise locations for dials, but (a little off-list) I 
have a bottle of Campo Viejo Rioja 2014 wine in front of me which gives at the 
top of the label N 42º 28’ 48† W 02º 29’ 08†. Although in a small 
font it is clearly printed above the brand name.

Google Earth shows a large vineyard, and indeed the brand, at this location.

This is a new one on me, and I wonder how many products are giving their source 
location in geographical coordinates.

Open for discussion!


As far as physical 'products' are concerned, these days they would
probably have a "QRcode" - you know, one of those small square blocks
which just seem to contain a 'jumble' of black and white pixels.

Those are mainly used to direct people straight to a website, but
they can contain a lot more information (if you needed to do so).

If you want to include an actual geographical location, then one of
the best ways is to use a "NAC code" - which stands for 'Natural Area
Coding' also known as Universal Map Coding, or a Universal Address).

It is usually included as a 'meta', within any website design coding.

For sundial-related subjects, the only people I know that use these
methods are "Modern Sunclocks" - and (if anyone is interested), I
have 'attached' the QRcode they use to drive people to their website.

Within the 'meta' code of that website they also display a NAC code,
so that any people can find-out their exact Latitude and Longitude.
