SPATIAL PROCESSING FOR MAP GEOMETRY SIMPLIFICATION

A method of simplifying a digital map for display is disclosed. The method comprises receiving a digital map for a geographical region, the digital map being organized into a plurality of raw map tiles associated with a plurality of sub-regions of the geographical region; retrieving configuration data related to visibility to humans for simplifying the digital map; identifying one or more features from each of the plurality of raw map tiles, each feature corresponding to a cluster of pixels, at least two features corresponding to a common pixel; generating a specific modified map tile for a particular raw map tile based on the configuration data by assigning a maximum of all values of pixels of certain features associated with the particular raw map tile that correspond to one or more common pixels to at least one pixel of the one or more common pixels not already having the maximum as a value.
