Google Maps and OpenStreetMap Data Views – Find The 10 Differences

Google Maps had The Atlantic over for a chat about how they work up their ‘deep map’ from various sources. It’s interesting to read about how Google invests incredible amounts of money and manpower to try and do the best job possible of capturing ground truth without people on the ground.

The article contains some ‘data views’ of Google Maps data in various stages of being worked up. I don’t know if it’s actual screenshots of an editing environment, but regardless, it’s an interesting peek behind the scenes that I had not had before.

This is from the article:

This is about the same area loaded into the OpenStreetMap desktop editor JOSM:

Now you can look long and hard to try and make out ten or maybe a hundred differences in the data, but there’s one difference between these two views that reaches much deeper. The data behind Google Maps you will never get to see, let alone touch. The data in OpenStreetMap on the other hand is there for anyone to download, use, make great products out of and, most importantly, edit and improve. That difference marks a cardinal characteristic of the Google Maps platform that the article failed to raise. Consider that itch scratched.
