Many of us use Google Maps on a daily basis, but do you ever wonder how they actually get made? The Atlantic managed to get a behind the scenes look at Google's "Ground Truth" project, which is attempting to build the most accurate maps possible using a variety of sources of data. For example, in America, it starts with a base layer using data from the US Census Bureau, and then things get more complicated with details from the US Geological Survey. Once you factor in things like Google's own Street View data, then you start to get something resembling the Google Maps we all use. It's a complicated process, so be sure to check out the source link below to get a rare glimpse into Google's map-making process.
