Google Earth updates its satellite imagery on a rolling schedule, not all at once
Google Earth does not refresh every image on the same day. Instead, satellite images update in waves across different regions — some areas get new photos every few months, while others may wait a year or longer between updates. The timing depends on which satellite company Google contracts with, cloud cover in that region, and how often Google prioritizes that location for fresh imagery.
When you open Google Earth and zoom into a city, the image date appears in the bottom right corner. That date tells you how old the picture is. A neighborhood might show imagery from three months ago while a rural area 20 miles away displays a photo from two years prior. This staggered approach lets Google balance the cost of constant satellite passes against the demand for current images in populated areas.
Key Takeaways
- Urban and suburban areas typically receive new satellite images every few months to a year, while rural and remote regions may wait one to three years between updates.
- The image date stamp in Google Earth's bottom right corner shows exactly when that particular photo was taken, not when Google added it to the service.
- Google contracts with multiple satellite providers including Maxar Technologies and Airbus, each with different coverage schedules and image quality.
- Cloud cover, seasonal changes, and the satellite's orbital path all affect whether a location gets a usable new image during a scheduled pass.
- You cannot request a specific location be updated, but Google's historical imagery feature lets you see how a place has changed over years or decades.
Why some places update faster than others
Google prioritizes satellite coverage for areas where the most people live and work. Major cities like New York, Los Angeles, and London receive new imagery several times per year because demand is high and the satellites pass over frequently. Suburban areas around these cities typically get updates every six to twelve months. Small towns and rural farmland might see new images only once every two to three years.
The satellite companies themselves determine the orbit paths and scheduling. Maxar Technologies, which supplies many of Google Earth's images, operates satellites that circle the Earth on fixed paths. A satellite might pass over Denver every three days but only reach a remote mountain valley once a month. Google cannot change these orbital patterns, so coverage frequency depends on geography and the satellite operator's business priorities.
Weather also plays a major role. A satellite might pass over Seattle on a cloudy day, making the image useless. The same satellite might need to wait weeks for clear skies before capturing a usable photo. Tropical regions with frequent cloud cover update less often than dry climates where clear days are common.
How to check when an image was taken
Open Google Earth on your computer or phone and zoom to any location. In the bottom right corner, you will see a date label — this is the capture date of the satellite image you are viewing. If you see "Image date: March 2024," that photo was taken in March 2024, not necessarily when Google added it to the service.
To see how a location has changed over time, use the historical imagery feature. On the computer version, click the clock icon in the toolbar at the top left. A slider appears showing all available images for that location, sometimes going back 30 years or more. You can drag the slider to jump between different dates and watch how a neighborhood, forest, or coastline has transformed.
The historical imagery feature only works on the desktop version of Google Earth, not the mobile app. If you need to check image dates on your phone, zoom in on the location and note the date stamp, but you cannot access the full timeline from the mobile interface.
Which satellite companies supply Google Earth imagery
Google contracts with multiple providers rather than operating its own satellites. Maxar Technologies is the largest supplier, operating the WorldView satellites that capture high-resolution images. Airbus Defence and Space provides images from its Pleiades and SPOT satellites. Planet Labs supplies some imagery as well, though their images are typically lower resolution than Maxar's.
Each company has different orbital schedules and image quality. Maxar's WorldView satellites can capture images with 30-centimeter resolution — detailed enough to see individual cars and buildings clearly. Airbus satellites offer similar quality. Older imagery in Google Earth sometimes comes from lower-resolution sources, which is why some historical images look grainier than recent ones.
Google does not publicly announce which satellite company captured a specific image or when the next update for your area will arrive. The company treats its satellite sourcing and scheduling as operational details rather than public information.
How Google Earth updates compare to other mapping services
Apple Maps, Microsoft Bing Maps, and other mapping services use similar satellite imagery sources, so their update schedules are comparable. Apple Maps often displays the same satellite images as Google Earth because both services license from the same providers like Maxar. Bing Maps sometimes shows fresher imagery in certain regions because Microsoft has different licensing agreements and priorities.
Mapbox and Esri, which serve professional users and developers, offer more frequent updates in some areas because their customers pay for current data. A real estate developer or city planner might use Mapbox to access satellite images updated monthly, while Google Earth remains on its slower public schedule.
Street View, which is Google's ground-level photography service, updates on a different cycle than satellite imagery. Street View cars drive through neighborhoods every few years, while satellites pass overhead more frequently. A street might have current Street View photos but older satellite imagery, or vice versa.
What affects image quality and freshness in your area
Population density is the strongest predictor of update frequency. If you live in a major metropolitan area with over one million people, expect satellite imagery to refresh every three to six months. In a mid-sized city of 100,000 to 500,000 people, updates typically arrive every six to twelve months. Small towns and rural areas often wait one to three years between updates.
Seasonal changes also influence what you see. Winter images in snowy regions may be less useful than summer ones because snow covers details. Google may skip a winter pass over a mountain valley and wait for summer when the landscape is clearer. Tropical regions with monsoon seasons face similar timing challenges.
The age of the satellite itself matters too. Older satellites sometimes produce lower-resolution images, which is why some historical Google Earth imagery looks pixelated compared to recent photos. As Google contracts with newer satellite operators, overall image quality improves, but older regions may still show outdated, lower-quality pictures.
Frequently Asked Questions
Can I request Google Earth update my neighborhood?
No, Google does not accept update requests from individual users. The update schedule is determined by satellite operators' orbital paths and Google's internal priorities. If you need current imagery for a specific project, you can purchase satellite images directly from Maxar or other providers, but this costs money and requires a commercial license.
Why does my street look different on Google Earth than in real life?
The image you are viewing may be several months or years old. Check the date stamp in the bottom right corner — if it says 2022 and you are looking in 2024, that explains why new buildings, trees, or road changes do not appear. Use the historical imagery slider to see when the most recent photo was taken.
Is Google Earth real-time?
No, Google Earth is never real-time. The newest images are typically weeks to months old by the time they appear in the service. Satellite imagery requires time to capture, process, and integrate into Google's system. If you need live or near-live satellite data, services like Sentinel Hub or Planet's public data offer more current options, though they require technical knowledge to use.
Do all countries get updated at the same rate?
No, update frequency varies by country and region. Developed nations with large cities receive more frequent updates because satellite operators prioritize populated areas. Remote countries and regions with less commercial demand may see updates only every few years. Political relationships and data licensing agreements also affect which regions get priority access to fresh imagery.
How far back does Google Earth historical imagery go?
Historical imagery availability varies by location. Major cities often have photos dating back to the 1980s or 1990s, while rural areas may only have images from the last 10 to 15 years. The oldest available image depends on when satellite companies began capturing that region and which images Google chose to archive. You can see the full timeline by using the historical imagery slider on the desktop version.
