Web 2.0 has enabled new location-based services through increased sharing of geographic data, collaborative intelligence, and continuous improvement. Some examples of location-based services mentioned are DialPlus which changes phone calls, Rough Guides which provides travel information for cities, and Kinjo which provides automated location finding services both outdoors and indoors using GPS and Wi-Fi. The proliferation of mobile phones and new technologies like cameras with geotagging capabilities are driving future trends in location-based web mapping services.
