Abstract: A method for searching a database for at least a recorded location data set includes: (a) deciding at least one facility availability condition; (b) searching the database for at least a specific recorded location data set matching the facility availability condition; and (c) displaying the specific recorded location data set found in the database that matches the facility availability condition.

Abstract: A routing method determines a route according to a distribution of POIs within a distance extending from the route. The distribution of POIs is derived from a POI density that is calculated by dividing an amount of POIs within the distance extending from a path with a length of the path. The cost value of the path is calculated by multiplying a weighting value to a length of the path, and the weighting value is given corresponding to the density. The route is then determined dependent on a cost value of the route derived by adding the cost values of all paths contained it.
