Method for providing data of a route profile in a vehicle, wherein - for a predefined route section first route profile data are determined, depending on data acquired by means of a predefined sensor device of the vehicle or of a further vehicle, the first route profile data being representative of at least one first local physical roadway property of the predefined route section, - provided encoded second route profile data are read in, which at least partly relate to the predefined route section, the encoded second route profile data comprising a spectral distribution and/or spectral distribution function determined depending on second route profile data, and the second route profile data being representative of at least one second local physical roadway property, - a measure of similarity between one or more progressions - represented in the first route profile data and the encoded second route profile data - of at least one physical property and/or spectral distribution function of at least one physical property is determined, - depending on the measure of similarity, decoding information for the encoded second route profile data is determined and - depending on the decoding information, the encoded second route profile data are at least partly decoded and provided, characterized in that the first local physical roadway properties and the second local physical roadway properties at least partly relate to different physical roadway properties or measurement variables and the first local physical roadway properties being at least partly assigned to a first class and the second local physical roadway properties being at least partly assigned to a second class, the first class and the second class differing in such a way that one of the classes comprises local physical roadway properties which are directly assignable to the roadway, and the other class comprises local physical roadway properties determined depending on a specific property of the vehicle and/or of a further vehicle. - for a predefined route section first route profile data are determined, depending on data acquired by means of a predefined sensor device of the vehicle or of a further vehicle, the first route profile data being representative of at least one first local physical roadway property of the predefined route section, - provided encoded second route profile data are read in, which at least partly relate to the predefined route section, the encoded second route profile data comprising a spectral distribution and/or spectral distribution function determined depending on second route profile data, and the second route profile data being representative of at least one second local physical roadway property, - a measure of similarity between one or more progressions - represented in the first route profile data and the encoded second route profile data - of at least one physical property and/or spectral distribution function of at least one physical property is determined, - depending on the measure of similarity, decoding information for the encoded second route profile data is determined and - depending on the decoding information, the encoded second route profile data are at least partly decoded and provided, characterized in that the first local physical roadway properties and the second local physical roadway properties at least partly relate to different physical roadway properties or measurement variables and the first local physical roadway properties being at least partly assigned to a first class and the second local physical roadway properties being at least partly assigned to a second class, the first class and the second class differing in such a way that one of the classes comprises local physical roadway properties which are directly assignable to the roadway, and the other class comprises local physical roadway properties determined depending on a specific property of the vehicle and/or of a further vehicle.
