A police officer who went on a rescue operation in a village is missing. How would you find the whereabouts of the policeman using the technological advances in mobile commerce?
What will be an ideal response?

Some location-based services are query based, allowing a user to request local maps and directions to points of interest, local traffic and weather information, or even information on the whereabouts of a friend or coworker.
