Claim 12:
13. A method of providing navigation information, the method comprising:
collecting first sound data captured by a sound capturing device at or proximate to a road segment;
determining whether the first sound data correspond to a sound type associated with a database including a map layer;
responsive to the first sound data corresponding to the sound type, generating a first data point for the map layer, wherein the first data point associates the sound type to the road segment;
responsive to the first sound data not corresponding to the sound type or any other sound types stored in the database, collecting second sound data captured by other sound capturing devices within a predetermined distance from a location at which the sound capturing device captured the first sound data;
determining whether the second sound data corresponds to the sound type or one of any other sound types stored in the database;
responsive to the second sound data corresponding to the sound type or the one of any other sound types stored in the database:
classifying the first sound data as corresponding to the sound type or the one of any other sound types stored in the database;, generating the first data point or a second data point, wherein the second data point associates the one of any other sound types to the road segment; and
storing the first data point or the second data point in the database, wherein the map layer comprises: (i) the first data point or the second data point; and (ii) one or more other data points that associate the sound type or one or more other sound types to one or more other road segments;
generating navigation information based on one or more data points stored in the database; and
causing a user interface to output the navigation information.
