According to Google, the data they compile from the Landsat program amounts to almost a petabyte or 700 trillion pixels. Scientists, researchers, environmental groups, and Google employees are just some people who access the information to learn more about the earth and how it changes over time. The Landsat program is government-funded, but the data it gathers is available to the entire world. All this information is put into a copy of the Google Earth Engine, which crunches all the data and creates the map. Google accesses these images and uses a sophisticated algorithm to detect cloud cover and replace overcast areas with previous footage to get an uninterrupted view of the world. These tools offer very detailed views covering almost the entire surface of the planet. Geological Survey’s (USGS) Landsat 8 satellites. Google Earth uses satellite-based photography from NASA and the U.S. After all, those areas do not serve as traveling necessities. This makes some sense, especially considering how often billions of people worldwide change their homes or backyards.

Smaller things, including examples like your new pool, aren’t deemed important enough for Google to update their content.

For example, if a new land development sprouts up with dozens of houses where there was once a field, Google will update this portion of the map quickly to ensure that they’re offering users not just the ability to see what’s around them but also new addresses of their friends. Rural areas, including much of the United States outside of the coasts, get updated at a much slower rate, only when something is considered important enough to update.

Cities like New York, Washington D.C., Los Angeles, and other important metro areas in the U.S. Regardless, the bottom line is you cannot find out when your area will get updated in Google Maps, although you can see where Street View will go next-more details on that later.Īccording to The Google Earth Blog in 2016, the more populated a place is, the more often it gets updated. For places more isolated, the frequency could be as slow as every couple of months, years, or even longer. In small, highly populated portions of the continental United States, updates happen as often as every week. Of course, multiple areas get imaged at the same time. Regardless, the update frequency depends on what part of the world is getting imaged from empirical data collection. Google doesn’t have a fixed schedule of updates for Google Maps, or if it does, it doesn’t release that information to the public. From this point, it is up to Google Street View to handle the details, which are discussed more below. Although Maps doesn’t display actual images and shows line imagery for roads, it serves its purpose well. The advanced imagery created by Google Earth, as further discussed below, provides clean results when zooming down to specific roads.

The more you zoom in, the more streets you see. Google Maps also zooms in more than Earth, down to small sections of a city. Google Maps includes the Google Earth imagery and adds streets and highways since that is its primary purpose. Google Maps provides personalized directions to help guide you to your destination.

Google Maps is part of the bigger “Google Earth” program and is the most commonly used part of Google Earth. Understanding Google Mapsīefore delving into how often Google Maps updates, you need to understand how it works-at least a little. This article discusses how Google Maps, Google Earth, and Google Street View work and how often they update. In fact, for some places, the maps may be years out of date! Many people have wondered how often Google Maps updates and how to find out when it’s going to update next for a given spot. What’s up with that? Google Maps doesn’t update in real-time or even with a great deal of frequency. Have you ever looked up your home or school or another place of interest on Google Maps, zoomed in, and exclaimed, “Hey! That’s not what it looks like now!” Maybe you installed or removed a swimming pool, or your neighbor’s old red barn burnt down two years ago, and yet there’s the old view of the property.
