Google launched their new indoor maps technology yesterday in Germany, allowing users to find their way round some of the harder to walk around buildings.
The first place to get the indoor maps treatment in Germany is the airports, for which Google has partnered with airports in Munich and Cologne, alongside it the service will also launch in various department stores including “Alster in Hamburg, KaDeWe in Berlin or Pollinger in Munich, many Saturn electronics markets (Cologne, Hamburg, Berlin, Dusseldorf and Munich), various arcade shopping centers and the German Museum in Munich and the Signal Iduna Park in Dortmund”
For all of these buildings maps have been provided to Google which has been uploaded to the service for use on both Android devices and on their PC Maps viewer.
To view indoor maps you will simply zoom in on a location which will then turn into an indoor map if available.
But this is only the first as the service will be making its way to other countries in Europe, however the service is already available in the UK , France , of Switzerland , Denmark , Sweden and Belgium.
