Abstract
A mobile device can send a request to a server having a plurality of tiles of location data associated with a venue, each tile having location data associated with a portion of the venue, the request including data representing an estimated location of the mobile device. The mobile device can receive a first tile of location data sent from the server, the first tile being associated with a first portion of the venue that includes the estimated location. The mobile device can receive a first sensor reading and determine a first location of the mobile device at the venue using the first sensor reading and the first tile of location data. The mobile device may receive a second tile of location data sent from the server, the second tile being associated with a second portion of the venue. The mobile device may receive a second sensor reading and determine a second location of the mobile device at the venue using the second sensor reading and the second tile of location data.
