Disclosed are methods, devices, systems, apparatus, processor-readable media, and other implementations, including a method that comprises receiving from multiple mobile devices, at a processor-based server, measurement data representative of sensor measurements performed by at least one sensor of each of the multiple mobile devices, and determining environmental characteristics associated with one or more environments at which each of the multiple mobile devices are located based on one or more environmental rules applied to the measurement data received from the multiple mobile devices. Also disclosed are methods, devices, systems, apparatus, processor-readable media for determining environmental rules based on sensor measurements provided by mobile devices for known locations or known environments. |
