Last month, in response to the news that Uber had acquired LBS platform provider deCarta, Marc Prioleau penned an article asking is this the start of a mapping war?

A few days ago, Bloomberg announced news that Nokia is looking to sell off HERE, the maps business forged from the, sometimes unwilling, union of NAVTEQ and Nokia's Ovi Maps. Potential buyers for HERE include ... Uber.

This looks like either a skirmish before an all out map war offensive or this is the start of that mapping war.

This may be a personal foible but when I join a new company I mentally set myself two targets. The first is what I want to achieve with that company. The second is how long it will take to achieve this. If you reach the first target then the second is a moot point. But if the first target doesn't get reached and your self allocated timescale is close to coming to an end, then it's time to take stock.

Sometimes you can extend that timescale; when reaching your achievement target is so so close and you can be happy to stretch those timescales a little. Sometimes though this just doesn't work, not necessarily for any reason of your own making. Large companies are strange beasts and a strategic move which is right for the company may not align with your own targets and ideals.

In 2010, I left the Geo Technologies group at Yahoo! and departed from a very Californian large company to take up a new role with a very Finnish large company called Nokia. Though Nokia started life as the merger between a paper mill operation, a rubber company and a cable company in the mid 1800's, by the time I joined Nokia it was best known for mobile and smart phone handsets and the software that makes these ubiquitous black mirrors work.

In addition to mobile data connectivity, apps and GPS, one of the things that defines a smartphone is a maps app and the suite of back-end platforms that drive that app as well as all of the other APIs that enable today's smartphone location based services. Just as TomTom acquired digital map maker Tele Atlas in 2008, Nokia had acquired rival maps provider NAVTEQ in 2007, putting in place the foundations for Nokia's maps and turn-by-turn navigation products, part of the company's Ovi brand of internet services.

Warning. This post contains a sweeping generalisation. Yes, I know that Places are not just part of today's digital maps; see the James Fee and Tyler Bell hangout The One Where Tyler Bell Defines Big Data as a proof point. But for the sake of this post, just assume that Places and maps are synonymous.

It's never been easier to make a map. Correction. It's never been easier to contribute to a map. Today we seem to be makingcontributing to maps everywhere, even underground, or should I say Underground?

To makecontribute to a map, you used to have to be a professional map maker, with easy access to an arsenal of surveying or an industrial grade GPS.

If you're an avid Foursquare user you can already display your last checkin, visualised on a map, in the sidebar of your WordPress powered site with the WP Quadratum plugin. Foursquare, checkins and maps ... what more could you ask for? Maybe the answer is more maps.

Version 1.1 of the WP Quadratum plugin, which went live this morning, now has added maps. The previous versions of the plugin used Nokia's maps, because I work for Nokia's Location & Commerce group and I wanted to use the maps that I work on. But if Nokia's maps aren't the maps for you then how about Google's, or maybe CloudMade's OpenStreetMap maps or perhaps OpenLayers' OpenStreetMap maps.

It's a glaringly obvious oversight but a few month's back I realised that given what I do for a living, there's something missing from my blog and that something is a map.

There's a whole slew of "where am I" style WordPress plugins out there, but after some careful research I decided that none of them did precisely what I wanted, which was to show the last check-in I made on Foursquare, on a map, in the sidebar of my blog.

Those that did come close still didn't do the key thing I wanted and that was to use the map I work on as part of my day job. Now don't get me wrong, I've got nothing against the maps that I could have used; Google, Bing, Mapquest and OpenStreetMap produce very fine maps and they all have the JavaScript API I'd need to display my last checkin. But none of them used my map and that means a Nokia Map.

In May of this year, Nokia announced the retirement of the Ovi brand and the observant map watchers amongst you may have noticed that pointing your browser of choice at maps.ovi.com now automagically redirects you to the new, shiny maps.nokia.com.

What you may not have noticed is that Nokia maps doesn't just work on your desktop or laptop web browser or on Nokia smartphones, as Electric Pig nicely pointed out, Nokia has invaded the iPhone too. Point your iPhone or iPad at the Nokia Maps for Mobile Web at m.maps.nokia.com and you'll see something like this ...

Yahoo's JavaScript and AJAX API was the first mapping API I ever used and it now seems hard to remember when Yahoo's API offerings were the dominant player, always iterating and innovating. The Yahoo! API set formed and continued to underpin the majority of my online presence. When I wrote about leaving Yahoo! and joining Nokia in May of 2010 I said ...

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.

... and I meant every word of it. The Yahoo! APIs were stable, powerful and let create web experiences quickly and easily. But now a year later a lot has changed. I still use Flickr on a pretty much daily basis, but Delicious is no longer a Yahoo! property and I transitioned my other web presence from using YQL for RSS feed aggregation to use SimplePie as YQL was frequently down or just not working. The original core set of Yahoo! APIs I use in anger is now just down to Flickr and YUI.

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.
