Traffic Payout

The is the first of several posts taking you behind the scenes of how Google makes its Maps. Stay tuned to the Lat Long blog over the next few days for the rest of the series. —Ed.

When you head out your door, you’ve got directions in your pocket—whether you’re driving to your aunt’s place in the mountains, cycling to a new biergarten or taking the train downtown. For Google Maps to get you there, it needs to be a digital mirror of the real world. But the real world is always changing. So to make sure your map is an accurate reflection of your world, we started Ground Truth, a project that brings the freshest, most relevant information to Google Maps.

Today, we’ve reached our 50th Ground Truth country with the addition of five new countries: Taiwan, Malaysia, Poland, Romania, and the last regions of Russia. We’re also rolling out Google Map Maker and Report a Problem—our crowdsourcing map tools—to Taiwan, Russia and Malaysia, giving anyone in those locations the ability to share and contribute their local knowledge directly to Google Maps.

For these countries, that means clearer, more detailed depictions of points of interest like walking paths in parks or department labels in universities, a reworking of the road network with new street names and turn restrictions, and faster updates to the map. In the unique case of Poland and Romania, both of which have Map Maker communities that were instrumental in building the map from scratch, it also means providing more resources to bring the same level of map detail to all regions in these places.

Over the next week, we’re pulling back the curtain to show you how Ground Truth and Map Maker work together to build Google Maps. Much of the magic behind Maps comes from people—from the Googlers who spend hours perfecting every road in the world, to the users who come together to improve the quality of maps in their local communities. To build the map, we have to gather high-quality information; in the next post, we’ll show you what that process looks like—and show off a new mapping technology.
