As you may have noticed, FME recently gained support for what3words, in the form of a couple of new transformers available for free on the FME Store.

In case you aren’t aware what what3words does, or how it might be used with FME, here’s a little bit more information for you.

What is what3words?

what3words is a web service that defines spatial locations through a system of three unique words. For example, the main entrance to Safe Software’s office building is located at helipad.sponge.falcon

w3w-safemap

It’s a 3m grid, so each square in the above image has a different combination of words.

What is the use of this? Well, firstly, not all of the world has proper street addressing available, and even if it does a set of simple words might be more memorable. Secondly, to share a location that has no specific address (for example when my car breaks down at the side of the road) it’s much easier to provide a set of simple words, rather than numeric coordinates.

And now, FME provides what3words support. Let’s see how…

what3words and FME: technical

what3words is supported in FME by a couple of transformers; the What3WordsEncoder and What3WordsDecoder. The encoder turns spatial positions into a what3words sequence; the decoder turns a what3words sequence into spatial features.

w3w-transformers

Because they are on the FME Store, you obtain the transformers by simply typing their name into Workbench (Quick Add). They should be available for both FME2015 and FME2016.

Both transformers require a what3words API key, which you can get by signing up on their web site (it’s a two minute task).

NB: Once you’ve put your API key into the transformer, use the button to save that as the default parameter value – then you won’t be searching for your key whenever you want to use it!

So it’s pretty simple to use what3words in FME – but what might you use it for?

what3words and FME: practical

Here’s a scenario I’ve been mulling over for a while.

w3w-graintruckMy wife works as a dispatcher for a trucking company in an agricultural area of Canada. The company picks up grain from farms and delivers it to grain elevators for shipping.

Dispatching trucks has the issue that farms rarely have a meaningful address. Traditionally farms are identified by a legal description based on the Dominion Land Survey; for example (thank you Wikipedia) a farmer might live at SE-12-20-33-W1 (South East quarter of Section 12, Township 20, Range 33, West of the first meridian)!

Plus… even if the farmhouse had an address, it doesn’t follow that the grain silo is at the same location; farms in Canada tend to be several hundred acres in size. So collection could be a long way from any single address point – or you might be picking up directly from the field itself as the crops are harvested.

I don’t have a definite solution, but I reckon what3words – with the bonus of a little FME Cloud automation – would do the trick; something like the following:

Alternatively, you could do the reverse:

I think there’s definitely some potential there – if you have any good ideas, please do let me know.

btw – did you look up best.integration.ever?! I did. It’s in Wyoming, USA. It’s quite fun looking up random words. I think a great trivia question at your local GIS group would be “do you know where worlds.highest.mountain is?”

    Hello Mark

    Funny that worlds.highest.mountain is near Vancover.

    Interesting too that worlds.best.marketing is a bit north in Alaska.

    what.three.words however doesn’t give any result !
    Read from that whatever you like 😉

      That is funny that there’s no what.three.words! Since I posted this folk at Safe have been experimenting too – with FME-related words like desktop.server.cloud and tester.logger.chopper. I think we could spend hours and hours combining transformer names!

    I’ve been looking at what3words lately and struggling to see how a proprietary address system is relevant in this day and age of technology. In scenario 1, the driver could easily use a simple web app (OSM, Carto, google, collector, leaflet, open layers etc etc etc) to store the pickup location in x,y coordinates and let a GPS take care of the collecting bit. The driver doesn’t have to remember the coordinates nor do they need to keep a spread sheet of convoluted 3 word combos. In scenario 2, the driver could get the pickup location and load it straight into a mobile phone web map or something similar to show them on a map (let the GPS which is using WGS84 or whatever else to do the locating). At no point is what3words needed or enhances the drivers experience with location. I’d be happy if someone can convince me that a made up grid of 3 word combos value adds anything to location intelligence but until then, I won’t be developing anything that locks an app into a propriety spatial grid. I might as well create a grid called AlexsWonderGrid and get everyone to pay for its use. AlexsWonderGrid will be made up of a 1m by 1m grid on wgs84 and i’ll name each grid with a unique pokemon name. When someone wants to turn their location from the pokemon name into meaningful map coordinates, I’ll charge a small fee. Although this example is hypothetical, it is exactly what what3words is. We need to take a critical eye to systems like what3words to avoid getting blind sided by a solution to a problem that doesn’t really exist. Does my opinion resonate with anyone else?
