Map With AI: RapiD Editor Interface
Facebook AI researchers and engineers have developed a new method for using deep learning and weakly supervised training to predict road networks from commercially available high-resolution satellite imagery. The resulting model sets a new bar for the state of the art for accuracy, and the data is now publicly available through Map With AI (https://mapwith.ai/).

If we’re going to map the world, we’re not going to do it with ever-greater volumes of elbow grease. There’s just too much work to do. AI and computer vision are helpful assistants in this task, however, as a collaboration between Facebook and OpenStreetMaps has shown, laying down hundreds of thousands of miles of previously unmapped roads in Thailand and other less well-covered countries.
The problem is simply that there’s a whole lot of Earth and only a handful of people actually making maps of it. Sure, Google and Apple have dueling products — but their focus is on businesses in cities and accurate navigation, not including every dirt path and gravel road.
Millions - People - Paths - Roads - Thoroughfares
Yet for millions of people, those dirt paths and gravel roads are important thoroughfares, and ought to be clearly marked on maps so that they can be reached by other modern services or, you know, get directions. With thousands and thousands of miles not just unmarked but difficult to make out, the mapping community has its work cut out for it.
“Most modern algorithms, training sets, and techniques were invented to work for the areas with highly developed infrastructure. In the developing world — for example, Africa, Southeast Asia, Latin America — where roads are not well-defined, maintained, or developed, even the best-trained human eye can struggle to identify and properly classify features,” said Dmitry Kuzhanov, a mapping expert in the ride-sharing industry, in a Facebook blog post about the AI-powered effort.
Facebook - Course - Folks - Services - Year
Facebook, of course, wants these far-flung folks to engage with its modern services. Over the last year and a half the company has collaborated with OpenStreetMaps and its users to map 300,000 miles of roads in Thailand, more than doubling what OSM had to begin with. The Map With AI effort resulted in RapiD, a machine learning-enhanced labeling tool...
