If you haven’t read the first two installments of the Beyond the Map series, they’re a good start in learning more about how we map the world and keep our data up to date. We want everyone on the planet to have an accurate, up-to-date map, but there’s a lot going on! So our work is never done and we have a variety of different efforts and technologies helping us keep our maps data as up to date as possible. Think about how frequently restaurants in your neighborhood come and go, and then consider all the businesses, buildings, homes and roads that are built–and then scale that up to more than 220 countries and regions that are home to more than 7 billion people in the world. The world is a vast and constantly changing place. How do you make sure Google’s maps data is accurate? So before we get to our third installment of the Beyond the Map series, we sat down with product director Ethan Russell to get answers to a few frequently asked questions about our maps data and how you can help us keep it up to date for your very own applications and experiences.

With more than a billion people using Google Maps every month and more than 5 million active apps and websites using Google Maps Platform core products every week, we get questions about where our maps data come from, how we keep it accurate, and more.
