Looking at nuclear disasters in Google Earth

mar 22-07-2014

Sylvan Lane at Mashable recently posted an in-depth look at nuclear disasters over the years, and he made solid use of Google Earth and Google Maps to explain each event. Along with discussions of Chernobyl and Fukushima, Sylvan also took a look at Three Mile Island and Kyshtym.

You can check out the full article for yourself over on Mashable.

To highlight other nuclear facilities around the world, the folks at Google Sightseeing have put together a few “nuclear power megaposts” over the years.

The first post covered nine reactors around the world, and the second post covered seven more. As they always do, they’ve posted KML files for all of the sites that they listed in the posts (part onepart two).

45th anniversary of the Apollo 11 mission

ven 18-07-2014

This Sunday 45 years ago, July 20, 1969, Apollo 11 astronauts Neil Armstrong and Buzz Aldrin became the first humans to set foot on the moon.

One great way to experience the landing is by viewing this amazing Google Earth tour that Sean Askay put together a few years ago.

As you can see in the tour, the landing that Armstrong made was remarkable. With very little fuel, he had to carefully maneuver the ship into a gentle landing. Paul van Dinther created a game to simulate the landing that he calls the Apollo 11 Moon Lander. The game is very fun, and quite challenging – here is a review written by Frank when it was released. In the years since then, Paul has updated the game with some new graphics, Facebook integration and bug fixes. You can also watch this short video of the game in action:

You can check out the game for yourself at

Lastly, of course, is the excellent “Moon” feature in Google Earth, released in 2009. There is some remarkably sharp imagery in places on the moon, and even 3D models of the Apollo 11 Lunar Module.

London goes 3D

ven 18-07-2014

Google has finally added 3D imagery to London, and it appears they’ve done a great job with it. As with other recent cities, it appears that their techniques for creating this imagery continue to improve and London seems to be the best-looking 3D city we’ve seen so far!

In particular, streets are smoother than many others we’ve seen, and buildings tend to have fewer random artifacts sticking out of them. It’s imperfect, but improving very quickly. As I’ve mentioned before, I hope that Google eventually uses street view imagery to improve it further, but this is certainly another step in the right direction.

To try it for yourself, you can grab this KML file to fly to London, and just make sure you have the “3D Buildings” layer turned on.

Google Begins Selling Their Own Imagery

jeu 17-07-2014

Part of the business model of Google Earth has always been that free access to seeing all of the imagery helped raise the visibility of the satellite and aerial photography businesses.  But, if a business wants to use this imagery, they are supposed to purchase the imagery from the provider mentioned at the bottom of the Google Earth screen (see Google’s geo-permissions guide).

During the past 10 years of Google Earth and Maps development, Google has increasingly developed sources of their own imagery.  Everyone is familiar with their Street View imagery.   Google’s 3D cities (introduced in 2012) are developed using aerial imagery which they also make available in their maps. And, with the purchase of Skybox, Google will soon have their own satellite imagery.

Now Google is taking the next step.  Google has announced their imagery will be available for sale, initially to businesses in the US through their Google Maps for Business imagery program.  The imagery can be used in a variety of ways explained in the program materials, including Google Earth.  Interestingly, in what was perhaps a mistake that fortells the near future, they state they are selling “high-quality satellite photography” in the announcement – although I think they meant to say aerial photography.

It should be noted that using Google Earth historical imagery feature (introduced in 2009), businesses can also view alternative imagery available from other imagery businesses if they are available for their location.  So, although Google is now competing with these businesses, their competitors have equal visibility.

Exploring earthquake fault lines in Google Earth

mer 16-07-2014

We’ve talked about Earthquakes quite a lot over the years, as Google Earth is a great tool for visualizing those types of events. However, we’ve not shown very much related to the actual fault lines themselves.

Ervin Malicdem at S1 Expeditions recently took a look at the West and East Valley Fault System in the southern Philippines. The fault line is growing in interest for a simple reason that Ervin explains:

The last known activity along this fault line was the year 1658 and is estimated to be active every 300 years plus or minus 100 years. As of the time of this writing, it has been 356 years ago and is well within the potential period of its movement.

He has created an excellent overlay that shows the fault line in comparison to infrastructure along the path of it.

You can read more on this blog entry or download this KML file to view it in Google Earth.

The USGS also has some solid fault line maps that you can use in Google Earth. If you visit their Quaternary Faults in Google Earth page, you’ll find a variety of KML files that you can download and explore in Google Earth.

Protecting uncontacted tribes in the Amazon rainforest with Google Earth

mar 15-07-2014

Scientists from the University of Missouri and the University of New Mexico have been using Google Earth imagery to track an uncontacted tribe in Amazon rainforest in Brazil. While Google Earth adds a level of convenience for the researchers, tracking the tribe from afar can be essential to their survival. From

Small populations like these risk imminent extinction due to various threats. But contacting these tribes may prove even more disastrous. Diseases commonplace in our society, like the common cold, can wipe out large portions of such tribes in a matter of days. Therefore, using satellite images to regularly and remotely survey their populations, and track their movements could prove a good non-invasive way of keeping a close eye on the tribes and protecting them from afar.

The researchers have had difficulty finding the tribe in more recent satellite imagery, possible due to the tribe’s movement to escape drug traffickers in the area, but they continue their search to regain information about their current location.

Be sure to check out the full article on the Mongabay website.

Goodbye Old Friend: Implicit Deprecation of the Earth Plug-in

lun 14-07-2014

This is a long winded guest post by me, Sean Maday, a guy who spends quality time thinking about maps and pondering about geospatial visualization.

Houston, we have a problem! The technology that brought mainstream 3D geospatial visualization to the web browser is rendering on borrowed time.

It appears that the Google Earth Plug-in is on the brink of deprecation.

Google has not made any official announcements about deprecating the Earth Plug-in, but the Google Chrome team has continued to push forward with their advancement of web standards.

In the Chrome team’s drive for modernization, they have announced that in September of this year Chrome will no longer support legacy plug-ins. As if to leave no doubt, they specifically mentioned our beloved Earth Plug-in.

The world has certainly changed since that day in October of 2008 when the Earth Plug-in was first released to the world. Back then there were no iPads, and Android releases weren’t yet named after desserts. In the time since, mobile has become pervasive and the web has been optimized for small screens; legacy browser plug-ins have become an anachronism.

I am personally still in denial about this harsh reality. I spent many hours of my life developing with the Earth Plug-in and showing off nifty 3D browser-based demos. It is hard to believe that those glory days of visualization are fading to memory.

As I march toward acceptance of this prolific deprecation, I am starting to date 3D technologies  again. I have played with Cesium, but she is rough around the edges and has the usability of an old handheld GPS unit. I have thought about licensing something from a traditional GIS vendor, but can’t justify the expense. In a moment of desperation, I even gave World Wind another, albeit fleeting, look.

None of those options are bad, they are just different, and won’t work for my 3D geo visualization needs.

My sincerest hope is that Google will announce an API for their WebGL instance of the “new Google Maps”. Although, even if a new 3D API is announced soon, I assume it won’t have feature parity with the Earth Plug-in, and won’t support the same instantiation and interaction methods.

That is to say, whatever 3D greatness Google releases next won’t be a plug-and-play replacement for the Earth Plug-in, and will require website administrators to refactor their code and redevelop their current offerings.

In summary, as I reflect back on all of the panning and zooming I have done in the Earth Plug-in, I am comforted knowing that I am a better neogeographer today for having crossed paths with this nifty piece of technology. On a personal level, I really hope that the Earth Plug-in enjoys her retirement.

Afterthought: It is unclear what a one year deprecation policy actually means when an entire class of technology is overcome by external events.

Update: It is important to note that Firefox has also started to distance themselves from NPAPI plug-ins like the Google Earth Plug-in:

Mapping slave history with Google Earth

ven 11-07-2014

A group of archaeologists in Asheville, North Carolina are using Google Earth to document the history of slavery in their city. The project is described as the following by Audie Cornish of NPR:

In Asheville, North Carolina, an effort is being made to do more in remembering the city’s slave history. A team of archaeologists is using technology to map gravesites in a cemetery that served the black community in that city for generations.

The maps have been around for a while, but in a less than useful fashion. As with many uses of Google Earth, adding geographical context is key as Jeff Keith explains:

Before we made this map and put it on Google Earth, we still had a map, per se. It was, you know, a flat, 2-D representation of the 1,961 graves that in the 1990s, a team of archaeologists went out and probed the earth and actually discovered were all these graves were. But it wasn’t on a map like it is now in terms of being represented in geographical space. Now we can see where it’s situated in the context of Asheville as a whole.

To see their work in action, you can visit the South Asheville Cemetery “online grave viewer”, which uses the Google Earth API to display the info directly on the site.

Finding Dinosaurs in Google Earth

jeu 10-07-2014

Pterosaurs, the first flying vertebrates that lived between 66-228 million years ago, went extinct around the end of the Cretaceous period. To help make it easier to understand where they lived, Matthew McLain at Loma Linda University has worked with come colleagues to put together PteroTerra, a Google Earth-powered database of pterosaurs.

An article on CBS News explains why McLain is tackling this project:

“Anybody can just pull this up really fast — the point being that you’d be able to plot where all these different specimens are on Earth, and you might be able to see if there was any sort of trend that maybe we haven’t noticed,” McLain said.

McLain said that other paleontologists have approached him to discuss starting databases for other ancient beasts, like the marine plesiosaur. He would like to create a database of dinosaur footprints and trackways, as a way to get a broader geographical view of dino travel.

To see the data for yourself, visit the PteroTerra website. The map page will give you a good overview, and then you can download the KML file to view all of the data in Google Earth.

Great work, Matthew!

Using Google Earth for crime analysis

mer 09-07-2014

We’ve talked about crime on here quite a lot over the years, many of which we discussed in this post last year.

Scott Dickson at Bair Analytics recently wrote a post that talks about some of the ways that he uses Google Earth to help with crime analysis. He talks about some great ways to use basic features, such as:

Another feature I use quite often is the “Show Ruler” tool. This tool allows you to measure distances on your maps. There are a number of criminal law penalty enhancements in Texas that increase penalties for offenses if they occur within a specified distance of a school. This tool allows you to easily determine just how close the offender was to that certain geographic feature.

He also talks about his bigger picture use of Earth:

Google Earth also makes it very easy to export your map as an image file that you can then drop into a report or presentation. I use this feature quite often when I create briefings on crime series or other types of bulletins. The old adage about a picture being worth a thousand words is true. By including maps in your presentations or briefings you can easily communicate geographic relationships. They also make your reports visually appealing.

It’s an excellent use of Google Earth, and it’s worth reading his full post at to learn more.

The differences between Google Earth and Google Maps

mar 08-07-2014

Google Earth and Google Maps used to be very different products, but over the past few years they’ve become much more similar. This is largely due to the addition of new features to Google Maps, such as support for 3D Imagery and other features that used to only be available in Google Earth.

The folks at Social Bubble recently wrote a post that discusses some of the difference between Earth and Maps. That inspired us to take it a bit further and lay out some of the differences.

To start, there are a handful of similarities between both programs. They both feature the same satellite imagery, allow you to search for locations, save places and get directions. In addition, both feature Street View imagery.

Google Maps
Google Maps offers a few advantages over Google Earth. It keeps your data synced across devices, has excellent turn-by-turn navigation features, and allows you to go into the past with historical Street View imagery. They recently crossed the one billion download mark, a testament to how popular it is.

Google Earth
While Google Maps is more convenient when you’re on the go (largely due to the turn-by-turn navigation), Google Earth has a lot of features that make it more powerful for digging in. Earth offers additional 3D content, makes it easier to stack layers of information, allows you to use special controllers such as the SpaceNavigator and the LEAP Motion, has an excellent flight simulator feature, allows you to view historical aerial imagery, and gives you additional tools such as the ruler and elevation profiles.

What is your favorite feature that you can only find in Google Earth?

Revisiting Louis Zamperini and Unbroken

lun 07-07-2014

(We first posted this three years ago, but sadly Louis Zamperini passed away last week so I thought it’d be a good time to check this out again. Enjoy.)

Last year, Laura Hillenbrand released a book titled “Unbroken: A World War II Story of Survival, Resilience, and Redemption“, based on the life of Louis Zamperini (details on Amazon). The book has been very popular, quickly becoming a best-seller and recently being picked up by Universal Studios to be turned into a movie.

The life of Zamperini is amazing, and the book is excellent. Zamperini, a world-class runner that competed in the Berlin Olympics in 1936, is drafted into World War II. He fights a number of missions before his plane goes down and he’s trapped in a raft at sea. After 46 days at sea, he floats into the Japanese-controlled Marshall Islands, and he’s placed in various POW camps for the next few years.

In reading the book about his journey, I realized that it would pretty cool to track down his various missions and POW camps in Google Earth. I was right! However, I was unable to find a decent timeline of his life, so I spent a few hours researching it and created one myself. After that, I did more research to find all of those locations in Google Earth and ended up with a pretty cool file.

The file includes locations from his early days (homes, school), the various places he went for military training, the Pacific missions he completed, the POW camps he was placed in, and the various stops on his journey home. You can download the KMZ file here to try it for yourself.

I had hoped that historical imagery might come into play with this, but the old imagery in the Pacific and Japan doesn’t go back nearly far enough (as opposed to Europe, where many locations have historical imagery dating back to the mid-1940′s). However, one good example was Hamilton Field, where he stopped over on his way to Hawaii. The present-day imagery no longer shows a runway, but if you switch to the 1993 imagery you can clearly see the runway still there.

All of that being said, I’m sure the file isn’t perfect. If you make any corrections to it, please email me the updated version ( and I’ll update this post.

So, have you read the book? What did you think of it?

Happy 4th of July!

ven 04-07-2014

Today in the US it is Independence Day, often referred to as simply the 4th of July. Banks are closed, BBQs are being heated up, and fireworks will fill the sky for most of us today.

Speaking of firewoks, here’s a neat post I found from Rick Klau a few years ago, when he used Google Earth to determine if he’d be able to view a local fireworks display from the comfort of his home.

He determined that fireworks typically reach a height of 300m, so he drew a polygon to that height, then used Google Earth’s terrain feature to see if the polygon was visible from his house. It was, and they enjoyed a great show that evening!

If you’re looking for more fireworks, check out the thousands of geotagged photos on Panorama tagged with the words “fireworks“. If you take any yourself, be sure to upload them on Panoramio for everyone else to enjoy.

For those of you running (or watching) the Peachtree Road Race in Atlanta today, our post from a few years ago shows you a lot of neat ways to view the course. The easiest is to simply load up this KML file and explore it for yourself.

Whatever you do today, have a great time and please stay safe!

Using Google Earth tour builder as a real estate agent

mer 02-07-2014

Since the introduction of Google Earth nearly a decade ago, it has been a great tool for real estate agents. One of the earliest examples was when Trulia added Google Earth support for real estate searches back in 2006. We’ve also seen property visualizations, Re/Max using Google Earth and many others.

Thanks to improved tools in recent years, particularly related to embedding Google Earth on websites, we’ve seen many other amazing pieces come along. A great example is what some agents are doing with Google Earth’s Tour Builder. An example is this handy tour of a home, which shows a variety of amenities and stores nearby to help give potential buyers a solid understanding of the area.

A great explanation of how realtors can use the tool came from Jason Fox, a realtor who has build some himself. From Fox’s blog:

By utilizing the Google Earth Application you can easily zoom around your community, neighborhood, city, or county and place a pin on the location you would like to highlight. Then add up to 25 Photos or Videos, Description, Title, Pin Style, and pan and zoom into your highlighted area to capture what you want your audience to see.

Once you have completed your tour you can share it with your client with a link to opens the Tour of your community.

The technology behind Google’s “Santa Tracker”

mar 01-07-2014

Back in 1955, CONAD (handing it off to NORAD a few years later) began “tracking” Santa on Christmas Eve night for children to call in and get his current location. Starting in 2004, that information has been available in Google Earth and it is a stunningly popular feature.

The technology behind Google’s latest Christmas Eve tracking service is quite impressive. As explained by an article on ZDNet:

By 2013, the Santa Tracker user experience grew into a full-fledged online, snow-kissed winter village with interactive HTML5 games, keystroke animations, a soundtrack, and of course, an elaborate Google Map that can even be integrated with Chromecast for viewing on larger screens.

As part of Google I/O, there was a session titled “How 20% engineers built Santa Tracker” that explained it quite a lot. The full video of that session can be seen here:

We saw some amazing new Google Earth-related stories in June, and here are some of my favorites.

We saw an amazing use of historical Street View imagery in Detroit, showing the rapid decay of some neighborhoods.

Hurricane season has begun, and Google has some tips for staying on top of the weather.

DigitalGlobe announced that they will be allowed to sell higher resolution imagery to companies such as Google, so look for that in the coming months.

We took a look at some more famous movie locations in Google Earth.

Thanks to Google Sightseeing, we looked at the rapid growth of kudzu in the United States.

We showed you the 12 stadiums being used for the 2014 World Cup.

The 2014 Tour de France begins soon, so we showed you a map of the entire course.

How to remove imagery from Street View

ven 27-06-2014

We get a few emails every week from people asking how they can get their image removed from Google Street View, so we thought we’d discuss it here. Thankfully, it’s a fairly simple process.

As you likely know, Google automatically blurs any faces or license plate numbers that appear in the imagery, as seen here:

However, sometimes a face will be missed or you’ll have some other reason to request that an image be removed. The steps are as follows:

  1. Locate the image in Street View.
  2. Click “Report a problem” in the bottom-right of the image window.
  3. Complete the form and click “Submit”.

That’s it! They’ll review your report and take appropriate action. You can use a similar technique in Google Maps to help update the map if you see any incorrect information (misspelled street names, etc).

For more, check out the privacy section on the Google Street View website.
