Americans inhabit an intricately
mapped world. Type “Burger King” into an online box, and Google will
cough up a dozen nearby options, each keyed to a precise latitude and
longitude.
But throughout much of the world, local knowledge stays local. While countries might conduct censuses, the data doesn’t go much deeper than the county or province level.
Take population data, for instance: More than 7.4 billion humans sprawl across this planet of ours. They live in dense urban centers, in small towns linked by farms, and alone on the outskirts of jungles. But no one’s sure where, exactly, many of them live.
Now, Facebook says it has mapped almost 2 billion people better than any previous project. The company’s Connectivity Labs announced this week that it created new, high-resolution population-distribution maps of 20 countries, most of which are developing. It won’t release most of the maps until later this
year, but if they’re accurate, they will be the best-quality population
maps ever made for most of those places.
The maps will be notable for another reason, too: If they’re accurate, they’ll signal the arrival of a new, AI-aided age of cartography.
In the rich world, reliable population information is taken for granted. (There are even nerd jokes about the need to remove population density from U.S. geographical data.)
But elsewhere, population-distribution maps have dozens of applications in different fields. Urban planners need to estimate city density so they can place and improve roads. Epidemiologists and public-health workers use them to track outbreaks or analyze access to health care. And after a disaster, population maps can be used (along with crisis mapping) to prioritize where emergency aid gets sent.
In the next half decade, a fleet of Silicon Valley-funded satellite companies will release many more terabytes of imagery to the public than was previously available to civilians. These photos will be cheaper than ever before, and they’ll be more recent: Thanks to cheaper rockets and advances in small satellite-building, some companies are promising “revisit rates” of six or seven times per week.
This new data won’t be valuable unless companies—especially financial companies—get good at deciphering it without human labor. Already, startups like Skybox (owned by Alphabet) and Descartes Labs say they’ve made advances in pulling information out of pictures without a person sitting at the table. If Facebook’s map works, it’ll be one more sign that such a goal is feasible.
