Abstract:

Techniques for storing information representing a venue are described. A venue data provider may upload venue data to a venue data service. The venue data can include locations, geometries, and business categories of the buildings and floors. The venue data service can validate the venue data, and request a survey service to survey the venue using the validated venue data. A survey can include recording measurements of an environment variable at various locations of the venue. The location service can generate location fingerprint data from the survey. The location fingerprint data can include expected measurements of the environment variable at various locations of the building. The venue data service can provide the location fingerprint data to a mobile device such that the mobile device can determine a location of the mobile device in the venue using sensor readings of the environment variable.
