Just a few years later, the Berkeley software engineer is editing digital maps so precise they include drinking fountains and benches in the Bay Area parks where he hikes, and the mapping community Dell inspiron 1520 battery has swelled to more than 240,000 global members. The effort, OpenStreetMap, is a kind of grass-roots Wikipedia for maps that is transforming how map data is collected, shared and used ¡ª from the desktop to smartphones to car navigation.
Volunteers have mapped everything from bike paths in Silicon Valley to bear cages in the Berlin Zoo, and added places like Nairobi slums that are often ignored by commercial cartographers Sony VGP-BPS8A ,Sony VGP-BPS9 . In the hours after the devastating earthquake in Haiti, OpenStreetMap produced detailed digital maps of a quake-altered Port-au-Prince that were crucial to relief workers on the ground, a "crisis mapping" template for future disasters
Its master Internet map is also based on large amounts of data uploaded by volunteer mappers who use GPS units to trace roads, trails and other features. In November, CloudMade released a free web application inspiron 1521 battery called Mapzen that allows people to edit the shape of a building, trace in a pond or label points of interest from benches to bike shops, together with an iPhone application, Mapzen POI Collector that simply lets users add points of interest.
Google also increasingly relies on feedback from users to make sure its digital maps are accurate and comprehensive, but it does not allow users to directly upload data into its maps, at least not yet. In the next few months, though, Google plans to introduce a product Sony VGP-BPS8 battery in the U.S. called Map Maker, which gives users much more power to customize maps.
And Tele Atlas, a company that supplies digital map data used for everything from car navigation devices to 911 dispatching, now allows individual users to suggest map changes directly from their navigation devices Dell 1525 battery .OpenStreetMap uses public mapping data from government agencies and aerial imagery donated by Yahoo and others.
