[Placelab-users] ApViewer problems

[<che...@si...>]

 Hi, placelab team
      Now, I am doing my project: "WiFi Positioning".So I need the placelab to show the longitude and latitude of the beacons. I can run ApViewer and it can find different APs but dosen't show the estimated coordinates. I' ve read the documentation but I can't find how to create the database and which file should the database be in? Could you tell me the detailed steps? I am really anxious!

Thank you very much!
