While mainstream #webmaps still route #pedestrians around the edges of open spaces, #OpenStreetMap engines like #OSRM and #Valhalla make the leap to true area #routing across squares and other open spaces. This shift beyond line-based paths brings digital #navigation much closer to real-world human movement and urban #walkability.

Apple has begun rolling out ads to its Maps app, displaying them in search suggestions and results with a blue "Ad" badge, though critics question their relevance and value.
