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.

Updated September 13th. 2012 with embedded YouTube video.

Wednesday September 5th. 2012 was a day of maps. To be precise, it was a day of maps, maps and MOAR maps. Two events, two talks, back to back. Packed choc-a-bloc full of maps. I also cheated slightly.

Firstly there was the International Cartographical Association's first session of the newly formed Commission on Neocartography. Cartography, neocartography, maps; what is there not to like? I'd previously spoken at the UK's Society of Cartographer's annual conference so it was great to be asked by Steve Chilton, SoC and Neocartography chair, to speak at the Neocartography Commission.

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.

Maps and map imagery seem to be back in the news. Google's recent map update and immense speculation about Apple's "will they, won't they" replacement for the current Google Maps app on iOS seems to be spilling over from the usual tech media into mainstream news.

Firstly, the UK's Daily Telegraph, a "quality broadsheet" seems to have just discovered that today's digital maps also have satellite imagery. It's not entirely clear how this is news, let alone current news. Navteq has had satellite imagery as part of its' maps since the mid 1980's and Google has also included satellite imagery in Google Maps since the mid 2000's. But linked to Apple's recent acquisition of 3D imagery specialists C3, we're told to anticipate a "private fleet of aeroplanes equipped with military standard cameras to produce 3D maps so accurate they could film people in their homes through skylights". The middle market tabloid Daily Mail has also picked up on this story, running with the headline "Spies in the sky that no one will regulate".

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.

And so, as Where 2012 draws to a close and the lobby of the Marriott Marquis in San Francisco fills with a slew of geo'd-out delegates waiting to check out, it's time for the traditional post conference retrospective writeup. If you were at Where this year or in previous years you'll probably want to skip ahead to the next paragraph, right now. Where, previously called Where 2.0, is one of the annual maps, geo, location conferences. Though it's very Californian and eye wateringly expensive, it's still the place to go to talk, listen and announce anything related to the nebulous industry we call Geo.

After skipping Where 2.0 last year, this year I returned as part of the Nokia contingent and found out that some things had changed.

Judging by comments to this blog post, on Twitter and on Google Plus, the consensus seems to be that yes, Apple is using OSM data from 2010 outside of the US; inside of the US it's (probably) TIGER data and no, there doesn't seem to be attribution and Apple may well be getting a communiqué from OSM to that effect. Other sources of information on this include * The iPhoto for iOS Not Using Google Maps thread on the OSM-Talk mailing list * Iván Sánchez Ortega has put up a nice map comparison between OSM and iPhoto's map tiles. * There's also another comparison between Apple's, OSM's and Google's map tiles. * Jonas. K has put up a blog post which comes right out and says that iPhoto is using OSM and other public domain mapping sources. * Finally, as a nice touch, this post seems to have made it into OSM Community Blogs.

In web and location circles, much has been made of Foursquare's recent "little announcement" of the location based, check-in, company's decision to oust Google Maps and instead to go with OpenStreetMap data, by way of MapBox.

From reading a lot of the coverage you'd be forgiven for thinking that Foursquare has completely severed ties with Google's mapping APIs, but this isn't quite the story. As ReadWriteWeb notes in the last paragraph of its coverage, "Foursquare's iPhone and Android apps won't be affected" as the move is for Foursquare's home on the web, foursquare.com, only.

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.
