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".

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.

Attempts to predict the growth, success and uptake of technology are rife. Accurate predictions, less so. "There's no reason for any individual to have a computer in his home", said Ken Olsen, then founder and CEO of DEC in 1977. "I think there is a world market for maybe 5 computers" is apocryphally attributed to Thomas Watson of IBM in 1943.

It's easy to say "well ... duh" with the benefit of hindsight in 2010 but consider this. The first generation of in-car GPS units appeared in 1996. If anyone had told you that 14 years later you'd be running something infinitely more sophisticated and customisable, more powerful than one of Olsen's DEC VAX computers that I started out on, on a device that you stuck in your pocket and which, by the way connected to a global network of computers and was also a telephone, you'd probably not have believed them or suggested that at a minimum they cut their coffee intake back.

This is not the blog post I set out to write. The one I set out to write was about Flickr, about machine-tags, about noticings and about transport data feeds. I had it all mapped out in my head during one of those wide awake in the middle of the night and your mind's buzzing moments. But as I started to research the blog post that I had set out to write, it mutated.

So with the caveat that I'm well aware that I'm making a sweeping generalisation whilst simultaneously doing a large disservice to a lots of specialist UK data providers ... 

Until recently, if you wanted a source of geo data in the UK you had three choices.
