Google’s map offerings build in the human intelligence on the front end, and that’s what allows its computers to tell you the best route from San Francisco to Boston.

In an exclusive story by the Senior Editor at The Atlantic, Alexis C. Madrigal, Google for the first time gives us a look at “Ground Truth”. It is a project described by Madrigal as a secretive, complex internal map that contains data, such as “no-left-turns and freeway on-ramps, speed limits and traffic conditions,” necessary to help users navigate through Google Maps:

I was slated to meet with Gupta and the engineering ringleader on his team, former NASA engineer Michael Weiss-Malik, who’d spent his 20 percent time working on Google Mars, and Nick Volmar, an “operator” who actually massages map data. 

“So you want to make a map,” Weiss-Malik tells me as we sit down in front of a massive monitor. “There are a couple of steps. You acquire data through partners. You do a bunch of engineering on that data to get it into the right format and conflate it with other sources of data, and then you do a bunch of operations, which is what this tool is about, to hand massage the data. And out the other end pops something that is higher quality than the sum of its parts.”

Describing Ground Truth to be an elaborate internal Map Maker of sorts, perhaps the most interesting aspect of the story is just how much human input goes into making the Google Maps experience accurate. In the story, Madrigal noted the Ground Truth Geo team aims to address most of the fixable problems reported by users (thousands daily) within minutes: expand full story

Brian McClendon Stories September 5, 2012

Today on the Official Google Blog, VP of Google Maps and Earth Brian McClendon announced Google is expanding Google Maps to new locations across the globe with the addition of new turn-by-turn navigation with traffic condition data, biking directions, as well as StreetView and Map Maker imagery. The first big addition goes to a number of towns across indian cities such as Bangalore and Delhi:

First, we’re expanding Google Maps Navigation (Beta) with voice guided, turn-by-turn directions in thousands of towns across India. Navigation is one of the most frequently requested features in this region and can be especially helpful when driving in densely populated cities like Delhi or Bangalore. We’re also adding live traffic conditions for major roads with estimated travel times to help you save time and to reduce stress on the road.

New Zealanders are also getting new access within Google Maps with the roll out of both Map Maker and Biking directions in the region. However, perhaps the biggest update today comes with new Street View imagery being released this afternoon for over 150 new university campuses around the world. Google noted a few of the more recognizable additions including UCLA and Royce Hall at the University of California in the U.S, Sophia University in Japan, Pembroke College in the U.K, and McGill University in Quebec. expand full story
