The mapping revolution could, in short, change the way we think of the World Wide Web. We’ve long spoken of the Web as if it were a place–with “sites” that we “go to”–but as places go, it’s been a rather abstract, disembodied one. Now that’s changing. Geotagging means the Web is slowly being wedded with real space, enhancing physical places with information that can deepen our experiences of them and making computing into a more “continuous” part of our real lives.
For example, users of smart phones and wireless PDAs with location technologies such as Global Positioning System chips may soon be able to automatically retrieve stories, photos, videos, or historical accounts related to their current locations, along with ads and listings for nearby shopping, dining, entertainment, and business outlets.
And the information is already flowing both ways: users can upload their own texts, photographs, and other data to the Internet and pin them to specific latitudes and longitudes. “Historically, maps were a ‘read-only’ medium,” says Schuyler Erle, chief engineer at Locative Technologies and coauthor of Mapping Hacks. “Maps were only created by professional cartographers and professional GIS [geographic information systems] people. What has happened because of Moore’s Law is that people now have the computing power on their desktops to manage the vast amounts of data that are required for digital cartography. Maps are increasingly a ‘read-write’ medium. That changes how we interact with them and the impact they can have on our everyday lives.”
