Even if you're not a cartographer, when you first see a map there's almost always a gut feel for whether you like a map or whether you don't. Critiquing a map is a deeply subjective thing. You may not know why you like a map but you can tell whether the map's cartography works or it doesn't work, for you at least.

The image at the top of this post is a great example of what I mean by this. It's a map of Berlin on the inside of an umbrella. Which is a great idea and this map is one I'm very fond of, both because of the time I spent in Berlin and because it was a present from one of my old HERE Maps team. But as a map, it's far from pleasing to me; I love what's being mapped, I just think it needs a better cartographer.

So much of what appears on today's digital maps is crowdsourced. Whether it's a totally crowdsourced map such as OpenStreetMaps' or a more focused effort such as HERE's Map Creator or Google's Map Maker, the so called wisdom of the crowd is an integral part of so many maps. But what would happen if you tried to crowdsource the critiquing of maps rather than the map itself?

Imagine for a moment you're in the city you live in; you know it like the back of your hand and yet you know there's shops, businesses or services nearby that you haven't yet come across. Or maybe you're in an unfamiliar city and you want to explore and stay away from the same old global brands that you see everywhere, in every city and on every street.

Now imagine putting this on a map.

"Ah hah!" you might say, reaching into your pocket and brandishing your smartphone. "I can do that easily" you say triumphantly as you fire up Google's or Apple's or HERE's mapping app.

But no, I'm talking about something a little more focused, a little less broad. "No worry" you say, firing up Foursquare, or Yelp or Facebook or TripAdvisor.

The geo industry has always been a fairly vaguely and nebulously defined industry and it takes a brave conference organiser to try and cover everything that's geo related in a single conference. But that's what GeoBusiness tries to do and it almost succeeds. This year's conference agenda and trade booth sideshow managed to cover the whole lifecycle of all things geo, from dodging drones, centimetre accurate GPS devices and LIDAR cars outside the Business Design Centre in London, through use of geo-data, with far too much BIM for my personal tastes, through mapping and cartography and ending up with crowd sourcing mapping data and using maps for emergency responses.

This year's high points were a jaw dropping talk on using airborne remote sensing to search for illicit nuclear explosions, surely a first for any conference I've been to, if only for the title alone and Chris Sheldrick from what3words recapping his talk on addressing the world. Less than high points were conference coffee that tasted like it had been brewed the month before and wifi that recalled the heady days of a 19.2K baud rate dial up modem. Thankfully the impending coffee emergency was prevented thanks to an espresso machine in the middle of the Leica exhibition stand and some rather fine coffee shops around the conference centre.

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.
