Abstract: A method of retrieving a map is disclosed. The method includes receiving a grid data of the map comprising lane segments, wherein the grid data includes an array of grids each associated with a list including none or at least one of the lane segments intersecting the respective grid; receiving coordinates of a location; identifying a first grid including the location based on the grid data; identifying a target grid that has an associated list including at least one of the lane segments as first lane segment; and outputting the first lane segment.

Abstract: Disclosed are devices, systems and methods for displaying a map for a user. A method of displaying a map for a user comprises: receiving, from a user device, a request to display the map for a geographical region around a vehicle, wherein the request identifies one or more layers of the map; retrieving, in response to the request, map data corresponding to the geographical region from a map database that stores a multi-layer representation of the geographical region; selecting, in response to the request, the one or more layers from the multi-layer representation; and displaying the map on a display of the user device based on the request.

Abstract: A computer-implemented method of map data processing, comprising generating, for a grid-based representation of map data, raw grid features; building a grid map by reading from a memory that stores the raw grid features; and processing the grid map using one or more post-processing operations including a smoothing operation applied across zero or more grid lines of the grid map according to a rule.
