Poorly illuminated driving or walking routes may be unpleasant or less safe. Current digital map and navigation applications do not explicitly factor illumination conditions into the navigation metric. This disclosure describes techniques to build a knowledge base of illumination of road segments and parking locations based on pre-existing data sources such as aerial/overhead imagery and street-level imagery. The knowledge base can be utilized for navigation route determination that takes into account illumination conditions, as well as for longer term decision making such as assigning scores to physical properties that can help users make property rental or purchase decisions.
