The new 3D cities on Google Earth for Android

Explorers of the world, rejoice! There is now a new way to explore the world, right from the palm of your hand. Gone are the days when the only way to get a bird’s eye, 3D view of your favorite metropolitan area was from the window of a penthouse apartment or helicopter. Now you can soar above your favorite cities in 3D, with Google Earth for mobile.

 

New 3D Imagery

We recently shared a preview of this striking new 3D imagery and starting today, you can take flight yourself with our latest version of Google Earth for Android. An updated version of Google Earth for iOS will be also be available soon.

 

 

 

New 3D imagery of Portland, Oregon

Creating this comprehensive 3D experience is possible due to advanced image processing. Using 45-degree aerial imagery, we’re able to automatically recreate entire metropolitan areas in 3D. This means every building (not just the famous landmarks), the terrain, and any surrounding landscape of trees are included to provide a much more accurate and realistic experience.

 

Get started today by taking a virtual flight over one of our initial 3D imagery cities: Boulder, Boston, Santa Cruz, San Diego, Los Angeles, Long Beach, San Antonio, Charlotte, Tucson, Lawrence, Portland, Tampa, Rome or the San Francisco Bay Area (including the Peninsula and East Bay). We’ll continue to release new 3D imagery for places around the world over the coming months; by the end of the year, we aim to have new 3D coverage for metropolitan areas with a combined population of 300 million people.

Tour Guide

Not sure where to begin? Let the new tour guide help show you the way. We’ve put together short tours of thousands of famous places and historical sites across the globe so it’s easier than ever to discover amazing places. Just pull up the tab at the bottom of the screen to open the tour guide. Each image highlights a tours or place of interest in the area you are looking. Click on an item and you will be flown there. As you fly in and around the sites, snippets from Wikipedia provide additional information about the location. It’s like having a local expert right beside you!

We hope this more accurate, comprehensive and realistic 3D representation of the Earth brings out the inner explorer in you. Whether you are visiting familiar grounds or venturing out into the world, Google Earth is there to show you the way.

The seafloor in Google Earth

More than two-thirds of Earth is covered by oceans. If you drained all of that water away, you’d see huge basins that have never been explored, an undiscovered planet in our own backyard.

Today is the three year anniversary of an explorable ocean seafloor in Google Earth. We just released a major update to our global underwater terrain dataset, called bathymetry, from the Scripps Institution of Oceanography, in partnership with NOAA, the US Navy, NGA, and GEBCO (with major contributions from IFREMER and IBCAO).

The update covers ocean topography from all over the globe and reveals our most accurate view of the seafloor to date. This new detail comes from spacecraft measurements of bumps and dips in the ocean surface as well as shipboard soundings from surveys carried out by over 40 countries. With this update to ocean terrain data in Google Earth, 15 percent of the seafloor is now available at 1 km resolution.

You may remember a Sun article reporting the discovery of a street grid where it’s believed the lost city of Atlantis would have been located off the West Coast of Africa. The discovery turned out to be a data artifact related to the way data was collected from a ship sailing back and forth to survey an unknown area. This recent seafloor update has been improved to blend better, and “Atlantis” has again disappeared into legend.

Previous terrain data showed what appeared to be a city grid on the ocean floor (left), which was confused for the lost city of Atlantis. Updated data more accurately reflects the seafloor terrain (right).

Another place you’ll notice an improvement in the ocean terrain data is the Mediterranean Sea, particularly south of Cyprus, where the boundary between the Eurasian and Arabian plates is now more clearly defined.

Our last example shows improvements to the land-sea mask along the coastline of Guam. You’ll notice a dramatic improvement in the resolution of both the coastline and neighboring Mariana’s Trench, the deepest trench in the world.

In order to make this update possible, our partners at the Scripps Institution of Oceanography at UCSD have curated 30 years of data from more than 8,000 ship cruises and 135 different institutions. If you’d like to get a closer look at these changes, watch our video tour of this new terrain.

We hope you enjoy diving deeper than ever in Google Earth!

Google Earth: High-resolution imagery in Antarctica

As Google has continually improved the quality of their imagery across the globe, one area always seemed to stay low-res — Antarctica. Thanks to the help of the Polar Geospatial Center (PCG), that’s beginning to change.

A great example of that is the Mackay Glacier Tongue, located in Granite Harbor, seen here:

You can see it for yourself, as shown in the article, using this KML file.

So far, the PGC has helped Google update nearly 1,000,000 square kilometers, with another 275,000 square kilometers added every three months. While it will take a while to get the entire continent updated (more than 14,000,000 sq km), they’re certainly making great progress.

Along with updating the quality of the imagery, they’re also working to improve the accuracy of the location of the imagery. The PGC’s Paul Morin will be heading down to the Antarctic Peninsula soon to help improve the imagery from being off by as much as 30 meters to being accurate within a single meter.

The full article at The Antarctic Sun is quite interesting and well worth your time to read. We all enjoy the constantly improving imagery quality in Google Earth, and the PGC is just one of many companies working with Google to help move things forward.
