The most detailed map of European population shifts
European population is not as mobile as American. While Americans are used to upping sticks and heading for new and greener pastures, in Europe lack of common language as well as cultural emotional attachment to home are significant factors stopping people from migration.
But the situation has changed. German Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) revealed the new trends with the most detail population map ever made in Europe. BBSR collected a data between 2001-2011 from municipalities all around Europe. The effect is amazing choropleth map map of unprecedented level of detail.
Although it’s incredibly detailed, the map is relatively easy to analyse. The different colours represent average annual population change for each municipality over the ten years studied. Blue means the population shrank, red means the population grew. Areas in beige have experienced no significant change. The darker shade of blue and red the more significant changes occurred. The different sizes of each coloured shape, meanwhile, show the radically different sizes of municipal units across the continent. Large areas in the Baltic States, Turkey or Scandinavia, and far smaller in Ireland, Greece, and the Czech.
Conclusions are quite obvious. Despite economic growth in Central and Eastern Europe, the continent is still migrating to the Northwest. We can see a lot of dark blue colour in Balkans or in Latvia with a significant increase in France or Ireland. Another visible trend is urbanisation. It is well visible in Poland where every larger agglomeration grew in favour of decreasing population of rural area. It is also visible on a large scale in east Germany and the north of Spain where Berlin and Madrit absorbed Citizens of small cities and villages in the range of 200 km.
Google Eddystone: What does the iBeacon Rival mean for next-gen Location based apps
Bluetooth beacons represent the next step in indoor positioning and are part of the larger Internet of Things (IoT) infrastructure. Using low-powered Bluetooth Beacons to send out location-based information and marketing content isn’t a new development. These low-power transmitters send out information to devices in their range and are as a tech-savy marketing departments’ dream (and for us, Location-based services fans) and now Google is the latest entrant to start working on this exciting tech, with project Eddystone.
Apple’s iBeacon, Facebook’s PlaceTips and now Google’s Eddystone
Apple entered the market in late 2013, increasing our interest in this cool new tech (Read: Will Apple’s iBeacon change the indoor positioning market) and they implemented their tech in a few places including the Apple Store. (Read: location-based discounts at Macy’s). Quite recently Facebook announced its own Bluetooth Beacon technology and service – Place Tips and they have already started rolling out their Bluetooth beacons to businesses in USA. So in some sense, Google is a late entrant to the arena.
Google Eddystone: an open BLE beacon format
Apple’s iBeacon has one major issue, and you probably guessed it already, it only works with iDevices. Eddystone is an open format that anyone can use, an important difference considering the number of non iDevice users. Google’s main focus for the Eddystone project is not sending you ads but instead sending you relevant information based on your location directly to apps like Google Now.
Eddystone is a protocol specification that defines a Bluetooth low energy (BLE) message format for proximity beacon messages. It describes several different frame types that may be used individually or in combinations to create beacons that can be used for a variety of applications. – Google’s Eddystone Github page
The Nearby API and Proximity Beacon API
Nearby API makes it easier to communicate with devices and beacons that are – well as the name implies – nearby. For e.g. specific bus stops, etc Google has already worked with the transport authorities in Portland, US to implement this.
What does it mean for Location-based Services?
An open format like Eddystone is definitely going to help tremendously increase the overall number of devices that are going to start using BLE tech for indoor positioning and location-based marketing. Back when Apple launched iBeacon in 2013, there was a lot of hype about how long it might take for Location-based marketing to become mainstream, we are yet to see that dream fully realized.
Google Now On Top + Location: #Geoawesomeness
The more exciting development could actually be in the machine learning and contextual information front. Google Now On Tap is widely regarded as the next killer application for android and interestingly it’s a contextual search app. For e.g. a simple “Ok Google, who wrote this song” is going to help find the name of the artist who wrote the song you are listening to, without having to leave the app or having to enter a detailed query. Google Now already has a lot of cool features and contextual location information will only help increase the number of things it can do with your location.
All this is great, what about using WiFi instead?
The Bluetooth vs WiFi debate has gone on for a while now and I am no expert but things are getting more interesting as a new standard is now going to let WiFi devices talk to each other. Maybe the future is going to see Bluetooth and WiFi tech co-exist and provide indoor positioning and push notifications.
