Systems and methods for collecting and using user-contributed map data

摘要

Systems and methods are provided for collecting and using user-contributed map data. In one implementation, a computer-implemented method is provided for collecting maneuver-specific annotations. According to the method, a user is presented with a set of computer-generated driving directions comprising a plurality of maneuvers. In association with presenting to the user the set of driving directions, the method presents to the user an option to submit an annotation for one of the plurality of maneuvers. In response to presenting the option to the user, the annotation is received from the user and stored in association with an identification of the one of the plurality of maneuvers. The stored annotation may be incorporated in the set of computer-generated driving directions.

1. A computer-implemented method, the method comprising:
storing, in a data storage, a first data table comprising a plurality of rows and a plurality of columns intersecting the plurality of rows to define a plurality of cells, wherein a first cell of one of the rows of the first data table comprises an identifier of a maneuver, a second cell of the one of the rows of the first data table comprises an annotation for the maneuver the annotation being based on input from a contributor, and a third cell of the one of the rows of the first data table comprises an identifier of the contributor; storing in the data storage, a second data table comprising a plurality of rows and a plurality of columns intersecting the plurality of rows to define a plurality of cells, wherein a first cell of one of the rows of the second data table comprises the identifier of the maneuver and a second cell of the one of the rows of the second data table comprises directional data for the maneuver; selecting, from the second data table, based on the identifier of the maneuver, the directional data for the maneuver; generating, with at least one processor, a set of driving directions for a user including the directional data for the maneuver; selecting from the first data table, based on the identifier of the maneuver, the annotation for the maneuver: determining, with the at least one processor, a reliability of the annotation; and providing the annotation in the set of driving directions for the user based on the determined reliability of the annotation, wherein providing the annotation in the set of driving directions for the user comprises displaying the annotation in association with the directional data for the maneuver.
