Tesla and Lithium

ven 01-04-2016

Tesla has started taking orders for the Model 3, its first electric car targeted at the mass market rather than the luxury car market. It was unveiled at a special even in California last night, March 31st, 2016. Tesla’s cars run on lithium-ion batteries. To make enough batteries for their cars, Tesla is building what will be the world’s largest lithium-ion battery factory, Gigafactory 1.

Tesla’s Gigafactory 1 under construction.

To make the batteries, they need large quantities of lithium. They are hoping to get a lot of it from a mine in Nevada, not far from Gigafactory 1. Read more about it here. They will, however, probably need lithium from all over the world.

Some lithium mines look pretty much like any other mine in Google Earth, but a number of the larger ones get the lithium from brine water pumped up from underground into large evaporation ponds. Evaporation ponds used for obtaining salt from seawater often turn red, as we have seen before but it seems lithium evaporation ponds tend to be turquoise, with occasionally some green.

While researching this story we came across an image in South America dated February 28th, 2015, which is not yet in ‘historical imagery’. This means that there has been at least one imagery update in Google Earth since the last one we reported. We will not be able to tell the extent of the update until the imagery is pushed into ‘historical imagery’.

The best of Google Earth for March 2016

jeu 31-03-2016

This month saw the fifth anniversary of the Great East Japan Earthquake and Tsunami. In memory of the disaster, Google released fresh Street View and aerial imagery. Some was captured soon after the disaster and some much more recently. Because the older aerial imagery would not be visible in the default layer, Google pushed the fresh imagery and other imagery from around the world that had been added earlier into historical imagery. This allowed us to create imagery update maps. This in turn gave us the opportunity to look at a few interesting places in the new imagery.

This month Sri Lanka got Street View. Although the blue outlines do not show in Google Earth, the Street View is available and there is a lot to explore. We also had a look at the Batcave in Street View and some Thailand Street View captured with the Trekker.

Thanks to a tip from GEB reader Jackson, we discovered that several buildings in Lexington, Kentucky have not been rendered correctly in Google’s 3D imagery.

The posts we most enjoyed writing this month involved creating animations. The first used Landsat imagery to watch an Antarctic ice sheet as it cracks. Then we had a look at the growth of artificial islands, first in the Persian Gulf region and then the rest of the world.

Google acquired satellite imaging company Skybox back in 2014 and this month renamed it to Terra Bella. The name change is intended to indicate a change of focus from just a satellite imaging company to pioneering the search for patterns of change in the physical world.

We had a look at fairy circles in Namibia and Australia and also found similar patterns in other parts of the world. Thank you to GEB reader for linking to this Google Earth Community post on the topic. It includes a KML that shows the extent of fairy circles in Namibia.

We had a look at the cluster of earthquakes in Oklahoma caused by pumping waste water from drilling operations into deep wells. As was noted in the comments by GEB reader David Newton the vast majority of these quakes were not big enough to cause damage.

We provided a few tips and tricks for Google Earth:
* We had a look at a technique for caching Google Earth imagery using Google Earth ‘line tour’ feature.
* We created a tool for reducing the size of KML files by reducing the precision of the latitudes and longitudes.
* We showed you how to create custom icons.
* We had a look at advanced techniques for formatting the print options in Google Earth Pro.

We showed you how our code for determining whether or not a point is inside a polygon works.

We discovered Street View portals to the Moon, Mars and Atlantis.

Street View Trekker visits Thailand

mer 30-03-2016

Thailand has had Street View as far back as 2012. This post on the Google LatLong Blog says that over 150 other places and national treasures have recently received Street View. However, many of the places listed have Street View dated 2014, and the first place mentioned, Sukhothai Historical Park, even has Street View from 2013. So either they have taken a really long time to process the imagery, or they have made a mistake somewhere. Nevertheless, Thailand has some really beautiful places and is well worth a visit.

Expect to see elephants, spikes and intricate carving.

The Oklahoma Earthquakes

mar 29-03-2016

Starting in 2009 the state of Oklahoma has seen a dramatic increase in seismic activity. According to Wikipedia, it has gone from an average of less than two 3.0+ Mw earthquakes per year to hundreds in 2014 and 2015. This has been caused by increased drilling for oil and the subsequent pumping of waste water into disposal wells deep underground. Read more here. As a result of the increased seismic activity, the U.S. Geological Survey (USGS) has released a new ‘damage map’ showing the risk of damage due to earthquakes significantly increased for the region. Read more about it here and find the map here.

Google Earth has a built in ‘Earthquakes’ layer found in the ‘Gallery’ layer. It only shows earthquakes over 3.0 Mw and as you zoom out it filters out the smaller ones. The result is that when looking at the whole of the continental U.S., Oklahoma doesn’t stand out as being particularly unusual.

However, the ‘Earthquakes’ layer is provided by the USGS and it is possible to obtain more detailed layers directly from them. Go here for automatic live feeds that show recent earthquakes, or here for more advanced queries.

If we choose the “Past 30 Days, M2.5+ Earthquakes” and “Colored by age”, the cluster in Oklahoma immediately becomes apparent:

We can also use the more advanced queries to compare 2008 and 2015:

Earthquakes 2.5+ Mw during 2008.

Earthquakes 2.5+ Mw during 2015.

To see the above in Google Earth download this KML file. The 2008 and 2015 datasets only cover the region around Oklahoma as the USGS website has a limit on the number of quakes allowed in a single query.

The Batcave now visible in Street View

lun 28-03-2016

As revealed by Google Maps Mania, “Bruce Wayne’s residence” has been captured in Street View and it includes the Batcave. It is not true Street View, but what Google calls either ‘Business View’ or ‘See Inside’. As such, it does not show up as the normal blue lines used for Street View, but rather an unassuming orange dot by the side of the road near Orion Charter Township in Michigan, USA.

To explore it in Google Earth download this KML file then place the yellow man on the location it marks. Alternatively, go here to explore it in Google Maps.

Once you have entered Street View you find yourself in a small, unassuming country residence by a lake. Walk to the end of the room and you will suddenly find yourself in an underground tunnel that leads to the Batmobile.

The Batmobile in the underground lair.

A Batsuit in the making.

According to Wikipedia, a number of different buildings have been used to represent Wayne Manor. The only one we were able to get close to in Street View is Wollaton Hall, found in Nottingham, England.

Watching artificial islands grow in Google Earth – Part 2

ven 25-03-2016

Yesterday we had a look at some artificial islands in the Persian Gulf region. Today we are looking at artificial islands in other parts of the world. We have chosen only islands that have been created or substantially modified within the time span of available Google Earth imagery (typically the last fifteen years or so).

Japan is mountainous and most of the available land on the coasts has been used. As a result, many of its airports are on artificial islands.

Haneda Airport, Japan, on an island itself, had an extra runway added that is on a new artificial island.

Kobe Airport, Japan.

Kitakyushu Airport, Japan.

Island City, Fukuoka, Japan. This is the only artificial island in Japan that we are featuring that is not an airport.

The Hong Kong–Zhuhai–Macau Bridge is, as its name suggests, a bridge connecting the three cities of Hong Kong, Zhuhai and Macau. The route consists of several long bridges and an undersea tunnel with artificial islands for the two entrances to the tunnel and a third island at the Zhuhai/Macau end of the bridge. As we have mentioned in the past, when satellite imagery extends into the oceans, Google Earth does not show it in high resolution. Sadly the Hong Kong end of the tunnel is, according to Google Earth, in the ocean and as a result the imagery showing it being constructed is out of focus.

The Zhuhai/Macau terminus.

The tunnel entrance in the Zhuhai/Macau direction.

The Maldives are a group of coral atolls in the Indian Ocean. Several of the atolls have been converted into more substantial islands.

Hulhumalé, Maldives.

Thilafushi (left) and Gulhi Falhu (right), Maldives.

We move on to Malaysia and its first man-made island – Marina Island.

Marina Island, Malaysia.

And finally we have Singapore, a small nation with a desperate need for more space.

Looking at the growth of artificial Islands in Google Earth

jeu 24-03-2016

There are quite a lot of artificial islands being built around the world. For example, last year we had a look at the islands that China is building in the Spratleys. Today we are looking at artificial islands in the Persian Gulf, where shallow seas and oil wealth create perfect conditions. In a later post we will have a look at artificial islands in other parts of the world.

We tried gif animations but the gif format has limited colours so we decided to create jpg animations with JavaScript. If they do not show correctly in your browser, please let us know in the comments.

We start with Bahrain, a small island nation that clearly feels the need to expand:

Amwaj Islands and Diyar Al Muharraq, Bahrain.

Durrat Al Bahrain, Bahrain.

Sitra, Bahrain.

Reef Island, Bahrain.

Next is the UAE, which is sprouting islands all along its coast:

The Palm Jebel Ali, Dubai.

Palm Jumeirah, Dubai.

The World, Dubai.

Then we have Qatar whose capital Doha is spreading into the ocean:

The Pearl, Qatar.

Lusail, Qatar.

Sri Lanka gets Street View

mer 23-03-2016

Google has recently released Street View for the country of Sri Lanka. Read more about it on the Google LatLong blog.

As of this writing the blue outlines for the Sri Lankan Street View are not yet in Google Earth, but the outlines do show in Google Maps and Street View imagery is available in both products.

Sri Lanka is the world’s fourth largest producer of tea and much of the Street View shows vast tea plantations.

Mackwoods is a tea brand, and we believe that is tea growing on the hillsides. See it in Street View.

Most of the roads in Sri Lanka are very narrow. Although there are cars and buses, motorbikes and especially auto rickshaws seem to be a very popular form of transportation. See it in Street View

The locals seem pleased that they are finally getting Street View. See it in Street View.

A temple being repaired. See it in Street View.

Caching Google Earth imagery with path tours

mar 22-03-2016

We have recently been catching up on the outlines for our KML of Google Earth 3D areas. The internet speeds here in Cape Town increase every year, but we still seem to spend a lot of time waiting for Google Earth imagery to load. When tracing out 3D areas, we have found it helpful to pre-cache an area before starting to draw and we thought we should share the technique, as our readers could find it useful in a variety of circumstances.

The border of the 3D imagery areas is often quite intricate.

The basic technique is very simple. Just draw a path where you wish to pre-cache imagery, then select the path and click the ‘Play Tour’ button that appears. Once the tour starts, go away and do something else for a while then come back when it is finished and you will find that imagery in the area you are interested in now loads much faster.

A ‘Play Tour’ button appears in the divider between Places and Layers whenever you select a path.

The default settings have the Google Earth ‘Camera’ follow the line quite closely and thus only imagery very near the line is cached. In addition, depending on the speed of your internet connection, the camera may move a bit too fast to fully cache the imagery before moving on. However, this can be adjusted with the settings found in Tools->Options->Touring:

We like to set the Camera Tilt Angle to zero (looking straight down) and the Camera Range to 1000 metres. Start the tour and see if the imagery is managing to load completely before it goes off screen. If not, reduce the Speed setting.

The above technique can also be used if you plan to use Google Earth offline, as you can pre-cache an area by drawing a zigzag path across it. Be sure to test it before setting off on a long journey.

To learn more about Google Earth’s cache see some of our previous posts on the topic.

What’s that Image: Fire, Flood and Mud

lun 21-03-2016

Today we are having a look at some of the interesting imagery we have been able to find in the latest Google Earth imagery update.
.sliders img{ max-width:none; }

In November last year there were a number of bush fires in South Australia. The imagery below shows the burn marks of one of those fires.

Drag the divider left and right to see the before and after images of a fire in South Australia.

December last year saw major floods in South America, including Uruguay, Brazil, Paraguay and Argentina. One of the cities that were hit hard was Asunción, the capital of Paraguay. They had already experienced floods in July, 2015, which we have looked at before. Judging by the imagery available, the December flooding was worse.

Flooding in Asunción, Paraguay

Be sure to explore the imagery in Google Earth. By January 20th, 2016 the flood waters appeared to have subsided a little, but the area above was still flooded. There is a problem with the imagery for the area, with Google Earth sometimes switching to the January image as you zoom in, even if the time slider is set to a December date.

On November 5th, 2015, Bento Rodrigues, Brazil, was inundated in toxic sludge after a mine dam burst. We had a look at the imagery of the site in January. At the time we were able to follow the mud a little way downstream. More imagery further downstream has now been released, including some images of the mud entering the Atlantic Ocean.

Watching Antarctic Ice Sheets Crack with Landsat Imagery

ven 18-03-2016

We recently came across this interesting story about an ice shelf in Antarctica which is slowly breaking off. The original story is on the NASA website here. The article features a couple of Landsat images captured in December 2013, and December 2015. However, Landsat imagery is freely available and relatively easy to obtain and put into Google Earth.

Our current favourite method for browsing Landsat imagery is with NASA’s Earth Explorer as it allows you to quickly browse through the imagery available and download low resolution versions, which can easily be put into Google Earth Pro.

In this particular case there is a surprising amount of imagery of the location in question. As we saw when we looked at the coverage that Landsat provides, the imagery is divided into rows and columns that cluster together towards the poles. This means that polar locations actually get covered by several adjacent columns and get imaged every couple of days or so. Most parts of the world only get imaged once every 16 days. However, the poles are also dark for about half the year so there will only be good images during the summer months.

In addition, many of the images have significant cloud cover, so we had to go through them and choose ones that showed a clear view of the location we were interested in. As you can see below we were able to obtain imagery all the way from January 2000 to March 2016. The latest image in the series was captured just last Saturday! (March 12th). There seems to be a bit of a gap in imagery around 2004/2005 but we did not investigate why.

Animation showing the ice crack moving and growing over the years. Larger version

You can see the ice flow like a very slow river. It moves approximately 3.8 km in the 16 year period shown above.

If you wish to explore the imagery in Google Earth you can download this KML file. We have had to crop the Landsat images considerably, showing only the location of interest in order to make the file a reasonable size.

The crack from the story has a precursor in 2000, which was as far back as we could go. However, it only lengthens and widens in 2013, when it starts to look like part of the ice shelf is breaking off.

The default imagery for the location in Google Earth is Landsat imagery from about January 2003.

Fairy circles

jeu 17-03-2016

In January we had a look at ant and termite colonies as seen from space. In that post we mentioned the phenomena of Fairy Circles from Namibia. Fairy Circles are regular patches of bare ground in the grasslands of Namibia as seen below

Fairy Circles in Namibia

A similar phenomenon has now been found in Australia. Read more about it here. This is what they look like in Google Earth:

Fairy Circles in Australia

There is Street View going through the area in Australia with Fairy Circles and you can see them along the sides of the road.

There has long been controversy over the origin of the Namibian Fairy circles, but the Australian scientists are fairly sure that the circles arise from feedback mechanisms related to plant growth and water run-off. They also predict that such patterns will arise in other parts of the globe with semi-arid conditions. So, we thought we would have a look and see if we could find any more examples.

The closest we have found so far are:


Burkina Faso.


The above patterns occur over vast areas. They are not quite the same as fairy circles and we could not find any ground level photos.

We also came across this interesting pattern in Australia:

Fairy Circles are patches of bare ground in grassland. This looks like patches of grass in bare ground.

St. Patrick’s Day with Google Earth

mer 16-03-2016

Tomorrow, March 17th is St. Patrick’s Day. St. Patrick’s Day originated in Ireland but is now celebrated in many other parts of the world. The United States, for example, has major celebrations in many of its cities. Green is the traditional colour of St. Patrick’s Day and many places in the world ‘go green’ for the occasion. This includes adding dye to fountains or rivers, painting roads or road markings or lighting up buildings or even whole mountains with green lights. See some examples here. We had a look though imagery captured on St. Patrick’s Day, but were unable to find any imagery of celebrations.

Although we couldn’t find any St. Patrick’s Day imagery, we did find some imagery relating to St. Patrick. St. Patrick is the patron saint of engineers, and the Missouri University of Science & Technology has an organization called St. Pat’s board. We were able to find their logo in two places in Google Earth:

Making KML files smaller by reducing precision

mar 15-03-2016

Our KML map of 3D areas has been steadily growing in size as new areas are added. We have considered converting it to KMZ format, which is the compressed version of KML files. KMZ uses standard ZIP compression and in many cases provides significant compression ratios. In our case it would shrink our KML file by over 60%. We have held back because this would mean changing the link to the file and as most users access it via a network linked KML we would also have to notify them to re-download the original KML with a new link. There are workarounds to this problem, so it might be worth doing. The other downside is that it adds an extra step to the process of updating the file as we would have to convert it to a KMZ file before uploading it.

Because of the above complications we have been giving some thought to other methods of making the file smaller. One thing we have noticed is that Google Earth saves KML files with an unnecessary amount of precision for latitudes and longitudes. It typically saves latitudes and longitudes using 16 significant digits. If you configure Google Earth to use decimal degrees then edit a placemark in Google Earth, it only actually shows 5 decimal places.

So how many decimal places are actually needed? We calculated that rounding to five decimal places results in a maximum error of just under a metre. Rounding to six decimal places gives an error of less than 10 centimetres. 14 decimal places gives an accuracy of less than a nanometre. Given that most Google Earth data such as altitude data or even image alignment can be off by many metres, having nanometre resolution in your KMLs is just wasting space. For our KML file five decimal places should be more than enough.

As you can see below, the results were quite impressive. Simply discarding unnecessary decimal places reduces the file size by almost half. We also show the effects of using the KMZ format.

We thought that other people with large KML files might find the idea useful. So, below is a JavaScript tool that will take a KML file and reduce the precision of the latitudes and longitudes.


  • The current version only reduces precision in placemarks, polygons and lines, it does not affect some other KML elements that include latitudes and longitudes.

  • To achieve the reduction of precision the code parses the KML and recreates it using our in-development KML library, so we can’t guarantee that it will properly handle unusual KML elements. If you use it, double-check that the resulting file still has everything in it that you require, and let us know in the comments if you encounter any bugs.

  • Unnecessary white-space is also removed which makes the file smaller but less human-readable.


Precision: (decimal places)

Google Earth Imagery update – February 2016

lun 14-03-2016

Google has finally pushed the most recently published imagery into the historical imagery layer, so we can find and map out the imagery. We have been aware of new imagery being in the default layer ever since Super Bowl 50, when Google added an image of the stadium captured on 1st February. But other than a few images we came across by chance we did not know how extensive the update was. Even now, we can only map out imagery by date, which means we can be sure that all February imagery is new and we can tell roughly how much January imagery is new by comparing with the map we made in January, but we do not know how much older imagery has been added.

Imagery in Google Earth dated February 2016.

Imagery in Google Earth dated January 2016.

To find the imagery in Google Earth download this KML file. It has been created using the Google Earth plugin and the outlines are only approximate. To spot the actual imagery switch to historical imagery when looking at one of the regions highlighted then switch back and forth between the most recent image and previous images and you will be able to see which images are new.

Cyclone Winston struck the islands of Fiji in the Pacific on February 20th, 2016. There are several images in Google Earth captured a few days later. However, they are poor quality and we have not yet been able to identify any damage caused by the cyclone.

The most interesting imagery we have found so far in this update is actually not recent imagery at all. Google has added a large quantity of aerial imagery of Japan captured not long after the 2011 tsunami. The imagery was added together with some aerial imagery from February 2016 as we mentioned in this post last week on the fifth anniversary of the tsunami. However, the older imagery had not yet been pushed into ‘historical imagery’ at that time so it was inaccessible.

It is well worth having another look at the devastation caused by the tsunami as the new imagery is noticeably higher quality than what has been available until now.

The above image was captured several weeks after the tsunami. You can see an upturned boat (1) amongst the debris more than a kilometre inland. You can also see cleanup operations beginning (2).

For the location of the above image use this KML file, but we highly recommend exploring the whole north eastern coast of Japan. Switch to ‘historical imagery’ and look for the aerial imagery captured in April 2011.

Some of the imagery was incorrectly processed and streaks off into the ocean, resulting in what we see below:

Custom Icons in Google Earth

ven 11-03-2016

When you create placemarks in Google Earth you can change the icon of the placemark by going to the placemark properties and clicking the icon button found just to the right of the placemark name. Google Earth then shows you a default set of icons you can use. However, it is also possible to use custom icons, which you can easily get from the web, or even create your own. Simply click the ‘Add Custom Icon…’ button and enter the URL of the icon you want or select ‘Browse’ to choose an icon you have created or saved to your local computer.

Also of interest is the option to set ‘No Icon’. This is very useful when you want to put plain text somewhere on the screen.

You can easily find a wide range of icons by searching on Google. The two best collections we know of are the icons provided by Google that are catalogued here and, which provides a variety of free icons specifically designed for maps.

There are a few things you need to be careful about when using custom icons. If you use an icon off the web using the URL and at a future date the website you linked to removes the icon, the icon will no-longer display properly in Google Earth. The icons from Google mentioned above should be pretty reliable, but if you get an icon from other sites and you are distributing your KML file, make a judgement as to how long those sites are likely to remain active and consider hosting the icons yourself or downloading them to include in the KML file.

If you use an icon from your local computer and you wish to distribute your placemarks in a KML file, make sure to save the placemarks in the KMZ format, as that will include the icons in the file. If you send someone the placemarks as a KML file, they will not have the icons and will see the red X that Google Earth uses when it cannot find an icon file.

If you add a custom icon it will remain in the list for the duration of the session, but if you exit Google Earth it resets the list to the default set and you have to add it again if you want to use it in new placemarks.

Google Earth’s default icon set has been updated in the past.

Below are some icons that we created for our own use. Feel free to download them to use in your own KML files. They work best if you do not give the placemark a name. If you want to include a name then create an extra placemark with no icon then you can adjust the position of the text. You can save the individual icons by simply right clicking on them and selecting ‘Save image as..’ (or the equivalent depending on your browser) or download the whole collection as a zip file here.

Google Earth Pro print options advanced formating

jeu 10-03-2016

When Google Earth Pro was first made available for free we had a look at the advanced printing options in Google Earth Pro that are not found in the standard version.

We recently had an enquiry from a GEB reader about how to change the background colour of the Title element. This YouTube video from Google gives some idea about what is possible and points out that the HTML Area element can contain just about anything that can be done with HTML, including an external website. However, it doesn’t mention that the Title and Legend elements can also be styled with HTML and CSS.

If you want a fancy title, one easy solution is to simply turn off the title element and use the HTML Area element instead, as that is easier to work with. However, if you want more than one section of text on your map you may find it easier to use both.

To change the background colour or transparency of the Title element, have a look at the contents of the HTML Area element element to get an idea of how it works there. The HTML Area element has a DIV with an id of ‘white_box’. It turns out that both the Title and the Legend boxes also have an identical DIV.

So for example, if you want to get rid of the background in the Title element simply edit the element and paste the following text anywhere. We recommend putting it at the end of the description for neatness.


The above also changes the heading and description to white to make them more visible. Note that the heading can be styled with the H1 tag and the description using the P tag.

The Legend element works exactly the same way – simply paste the above or your own styles into any of the legend entries.

Unfortunately, it seem that CSS gradients are not supported.

If you spend a long time working on the print settings be sure to save them, as they will otherwise be lost when you exit Google Earth Pro.

The above Title was formatted by adding the following text to the description:

<style>#white_box {background-color: #a2d7d8;border:5px #fcd059 solid;border-radius:20px}h1{color:#de5842;text-align:center}p{color:black;text-align:center;font-style:italic;font-weight:bold}</style>

Google’s Skybox Imaging renamed Terra Bella

mer 09-03-2016

Google has just announced that Skybox Imaging has been renamed Terra Bella. The new name is intended to indicate a change of focus from just a satellite imaging company to pioneering the search for patterns of change in the physical world.

Google acquired Skybox Imaging back in June 2015. We have not seen Skybox imagery in Google Earth, mainly because it is lower resolution that than offered by Google’s usual imagery suppliers. Despite the lower resolution, Skybox has produced some interesting products over the years. We saw a gif animation of the Burning Man festival and in the same post you can see the first HD resolution video of Earth from space. We also had a look at Skybox’s image of the November 2014 Poppy display at the Tower of London. We love the Google Chrome extension “Earth View” and we noticed that it includes a few images from Skybox Imaging. In October 2014 Skybox announced the Skybox for Good programme, which works with non-profits to provide fresh satellite imagery where they need it.

Terra Bella plans to launch a lot more satellites in the coming years and we hope to see great things from them in the future.

As of this writing, the old domain, seems to be inaccessible, making any links to the old Skybox Imaging blog no-longer valid.

Thank you to GEB reader Eric for letting us know that the Terra Bella name is derived from the street where they have their offices (Terra Bella Ave, Mountain View, California, USA).

Fifth Anniversary of the Japanese Earthquake and Tsunami

mar 08-03-2016

This week marks the fifth anniversary of the Great East Japan Earthquake and Tsunami. Google has been using Street View and aerial imagery to record both the devastation caused and the subsequent rebuilding process. They have recently released a new batch of Street View imagery for some of the worst affected areas, allowing you to see the changes over the last five years. Read more about it on the LatLong blog. You can also explore the imagery at the “Great East Japan Earthquake Digital Archive Project”.

Google has also been gathering aerial imagery of Japan, including the affected areas. They have recently released some imagery dated February 2016. It is not yet in ‘historical imagery’ but can be found in the default layer. It is unusual for aerial imagery in that it shows quite a lot of snow cover. The LatLong blog shows an animation of one location showing the situation before the Tsunami, the devastation caused and the recovery and rebuilding process to date. Below we show similar images for another location. You could do the same for almost any location along the North East coast of Japan.

August 2010, before the Tsunami.

March 2011, showing the devastation after the Tsunami.

February 2016, showing rebuilding taking place. However, they are avoiding building houses within the danger zone.

We have marked out the areas covered by the new 2016 aerial imagery, which you can view in Google Earth with this KML file.

Google did some similar imagery comparisons one year after the disaster, which we covered here.

Total Solar Eclipse March 8-9, 2016

lun 07-03-2016

This week there will be a total solar eclipse starting in the Indian Ocean, crossing Indonesia then out into the Pacific, ending up North East of Hawaii. A partial eclipse will be visible longitudinally from India to Alaska and latitudinally from China to Australia. An interesting side effect of the fact that it crosses the dateline is that the eclipse starts on March 9th and ends on March 8th.

One of our favourite resources for eclipses is the HeyWhatsThat eclipse page. It depends on the Google Earth plugin, which was set to be shut down last December, but has been kept running by Google so far, and you can still view the HeyWhatThat website with Firefox. You will have to allow the plugin to run.

Another excellent resource is Xavier Jubier’s site, which has this page that has a lot of detailed information about the eclipse and local viewing conditions and this map, which shows the path of the eclipse and a number of viewing locations, including a number of cruise ships and aircraft that appear to be planning to view the eclipse.

If you don’t live in the path of the eclipse then it is possible to view it online. It will be live-streamed by Slooh, a community telescope service. However, to view it you need to sign up as a member. They are currently offering one free month’s membership, but they do seem to require a credit card.

See here for previous solar and lunar eclipses.
