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.
