Abstract
Methods and systems are provided for generating an electronic map display. In one implementation, a method is provided for determining a route distance based on information for a route, comparing the route distance with a distance threshold, defining a search area when the route distance is less than the distance threshold, the search area including boundaries, calculating, using a processor, a points of interest (POI) density of the search area, comparing the POI density with a first density threshold and a second density threshold, adjusting the boundaries of the search area based on a result of comparing the POI density with the first density threshold and the second density threshold, identifying POIs in the adjusted search area, and providing POI information for an electronic map display, the POI information being associated with one or more POIs identified in the adjusted search area.
