It is a layer that you use within the mobile application Layar.
All entrances to the Stockholm metro system.
I used a bunch of different map services such as Eniro and Google Maps to locate the entrances.
I tried contacting SL to get more exact coordinates but they didn't want to help me in any way.
Because of this there might be some inconsistencies in the information, if you find any entrance that is missing or in the wrong place, please don't hesitate contacting me using this form
First thing you need is a smartphone able to run the application Layar, right now that means an Android or iPhone device.
