Nowadays people use maps everyday in many situations. Maps are available and free. What was expensive and required the user to get a paper copy in a shop is now available on any Smartphone. Not only maps but location-related information visible on the maps is an obvious feature.
This work is an application of opportunistic networking for the spreading of maps and location-related data in an ad-hoc, distributed fashion. The system can also add user-created information to the map in form of points of interest. The result is a best effort service for spreading of maps and points of interest. The exchange of local maps and location-related user data is done on the basis of the user position. In particular, each user receives the portion of the map containing his/her surroundings along with other information in form of points of interest.
