Using Web Tools, Amateurs Reshape Mapmaking

By Christopher Berkey for The New York Times

On the Web, anyone can be a mapmaker.

With the help of simple tools introduced by Internet companies recently, millions of people are trying their hand at cartography, drawing on digital maps and annotating them with text, images, sound and videos.

In the process, they are reshaping the world of mapmaking and collectively creating a new kind of atlas that is likely to be both richer and messier than any other.

They are also turning the Web into a medium where maps will play a more central role in how information is organized and found.

Already there are maps of biodiesel fueling stations in New England, yarn stores in Illinois and hydrofoils around the world. Many maps depict current events, including the detours around a collapsed Bay Area freeway and the path of two whales that swam up the Sacramento River delta in May....

“What is happening is the creation of this extremely detailed map of the world that is being created by all the people in the world,” said John V. Hanke, director of Google Maps and Google Earth. “The end result is that there will be a much richer description of the earth.”

...Yet that is nothing compared with the boom that is now under way. In April, Google unveiled a service called My Maps that makes it easy for users to create customized maps. Since then, users of the service have created more than four million maps of everything from where to find good cheap food in New York to summer festivals in Europe.

More than a million maps have been created with a service from Microsoft called Collections, and 40,000 with tools from Platial, a technology start-up. MotionBased, a Web site owned by Garmin, the navigation device maker, lets users upload data they record on the move with a Global Positioning System receiver. It has amassed more than 1.3 million maps of hikes, runs, mountain bike rides and other adventures.

On the Flickr photo-sharing service owned by Yahoo, users have “geotagged” more than 25 million pictures, providing location data that allows them to be viewed on a map or through 3-D visualization software like Google Earth...
