Using GPS and maps on mobile phones

Over a year ago I wrote Mobile Phone futures, with a few key ideas on how location-aware mobile devices / phones could potentially revolutionise how we navigate and get information on unfamiliar surroundings.

Google recently announced Google Maps with “My Location” technology that does just this for all mobile devices, whether they have built in GPS or not. For phones with built in GPS like the high end Nokia N95, the maps displays a constant location indicator. For phones without built-in GPS, it displays the current position based on some form of triangulation of cell phone towers.

Google Maps for Mobile runs on most J2ME-enabled devices, including BlackBerry phones, Windows Mobile, Palm, and Symbian devices.

Clearly a technology that has uses beyond navigating London or urban areas.
