Yesterday, Google launched their Maps Engine Lite beta; a way of quickly and easily visualising small scale geographic data sets on (unsurprisingly) a Google map. The service allows you to upload a CSV file containing geographic information and style the resulting map with the data added to it. I thought I'd give it a try.

I turned to my tried and trusted data set for things like this; a data set I derived from a Flickr set of geotagged photos I'd taken of the London Elephant Parade in 2010. It's a known data source and I know what the results of this data set will give me; it lets me do a reasonably meaningful visual comparison of how a particular product or service interprets and displays the data.

Back in 2010, when I left Yahoo! to go and join Nokia, I wrote some words that at the time seemed full of hope for the future of the Geotechnologies group I'd left.

I’ll continue to use my core set of Yahoo! products, tools and APIs … YQL, Placemaker, GeoPlanet, WOEIDs, YUI, Flickr and Delicious. Not because I used to work for Yahoo! but because they’re superb products.

Time and changes of corporate heart have not been kind here. Maybe it's time to take a look at the state of the geo union.

First a disclaimer; there's one elsewhere on this blog but this post merits another. I used to work for Yahoo! as part of the Geo Technologies group. I now work for Nokia as part of their Location group. The opinions and ideas expressed in this post are absolutely just my own, and should not be confused with, or taken for, those of my current or past employers. It's just me here.

You may not have realised it but Friday May 27th. was a sad day for the Geo industry in London. Even without the benefit of knowing what was going on from ex-colleagues inside the company, the signs were there if you knew where to look for them and how to read them.

Before the Internet, companies, teams and projects could fade quietly into anonymity and into oblivion. But on the Internet, everything is in public and it's much harder to hide the tell tale signs. API updates and bug fixes cease. A web site or blog stops being updated or goes down altogether. A Twitter feed stops being an active living thing and becomes merely a historical record. Ex-colleagues start following you on Twitter or you start getting connection requests on LinkedIn whilst other colleagues start polishing and updating their LinkedIn profiles.

And May 27th. 2011? That was the day that the last of the remaining members of my old team at Yahoo! Geo Technologies left the Yahoo! office in London and that was the day that Yahoo! ceased to have a Geo presence in the UK.

About 6 months ago, when I announced that after 4 years I was leaving Yahoo! to join Nokia I wrote ...

So whilst I’m going to Nokia, I’ll continue to use my core set of Yahoo! products, tools and APIs … YQL, Placemaker, GeoPlanet, WOEIDs, YUI, Flickr and Delicious. Not because I used to work for Yahoo! but because they’re superb products.

That's still true but the recent news of the closure, or shutting down, or selling off of Delicious has been one of those significant events that makes you sit up and take notice. In this case, it's made me take notice of just how much I rely on the vague and nebulous technology we call the Cloud.

Last month I wrote that a map says as much about the fears, hopes, dreams and prejudices of its target audience as it does about the relationship of places on the surface of the Earth. With the benefit of hindsight I think I was only half way right.

Sometimes a map becomes more than just a spatial representation and becomes something else.

Sometimes a data visualisation becomes more than just the underlying data and almost takes on a life of its own.

When these two things meet or collide the results can be spectacularly compelling and produce, unintentionally ... art? Look at the image below ... filigree lace work? Crochet for the deranged of mind? Silk for the sociopath? Macrame for the mad? Sadly none of the above.

It's instead an image from the Geotagger's World Atlas but it's still unintentionally beautiful.

Longitude and latitude have been formally used as a geographic coordinate system offset from the Greenwich Meridian since the International Meridian Conference of 1884 in Washington D.C.

As a spatial coordinate system, longitude (abbreviated as φ, or phi) and latitude ( λ, or lambda) work very well in defining a point on the surface of the Earth. But to gain further meaning from a long/lat pair you either need some clever algorithmics or you need to plot the long/lat point on a map which even then will yield information only as good as that which is rendered on the map itself.

Which is why I think identifier systems, such as Yahoo's WOEID, add so much value. A WOEID adds a linked web of rich metadata, describing not only a point with a long/lat centroid, but also reinforces the concept of a place, with neighbouring and hierarchical relationships.

Coordinates describe the where of a place, identifiers such as WOEIDs describe the how of a place but both conveniently (in a slight embarrassed, foot shuffling short of way) overlook the when of a place.

I take a lot of photos, most of which end up on my Flickr photo stream. While some of them are taken with a proper camera  (though some would say that my Lumix FX12 isn't a proper camera), most of them are taken with my iPhone, which doesn't take great pictures but takes pictures which are good enough and with the added bonus that I have it on me almost all of the time.

My photos all used to be publicly accessible and with an all rights reserved copyright on them but then I lost my Flickr innocence, which was a bad thing at the time and switched all of my photos to friends and family visibility. About a week later, when I'd calmed down a bit, I went through all of my photo sets; photos of my family and of home stayed out of the public eye and stayed all rights reserved. But everything else, I opened up and changed the license to some rights reserved using the Creative Commons Attribution Share-Alike license.

We all produce lots of online content these days; photos, videos, blogs, microblogs, status updates, Tweets, that sort of thing. Most of the pictures I produce go up on my Flickr account and there's a lot of photos, almost 3.5 thousand at the last count. Most of these almost 3.5 thousand photos are of my family, my wife, my children and last year I changed my default upload model from "anyone can see this" to "only friends and family can see this" and I went back and changed permissions on those photos I'd uploaded. On all of them. Or so I thought.

I'm writing this in my hotel room in New York, where I've been taking part in Yahoo's Open Hack NYC event and I've been taking a lot of photos which I've been posting to Flickr. Some people seem to like these photos and favourite them; each time this happens I get a nice friendly mail from Flickr telling me this. So this morning I went and looked at all the photos of mine that had been added as a favourite and I didn't like what I found. There was a photo taken last year while on holiday; a photo of one of my children, a photo which I thought was "friends and family only".
