The best of Google Earth for May 2017

We saw a lot of imagery of flooding this month, including:
* The ongoing flooding in Sri Lanka.
* Flooding in Peru, New Zealand and Madagascar.
* Another look at the Peru floods.
* Flooding in Queensland, Australia.

Using Sentinel-2 imagery we saw two large tornado tracks crossing Canton, Texas.

We had a look at a crack slowly forming in Larsen C ice shelf, Antarctica. When it eventually breaks off, the iceberg created will be about 5000 square kilometres and will be among the largest icebergs ever recorded.

We had a look at a number of landslides in Kyrgyzstan, a country which seems to be particularly prone to landslides.

We did a series of posts looking at satellite and aerial imagery calibration targets around the world. Some were quite difficult to find, but in the end we had quite a large collection.

We enjoyed Google’s April Fool’s joke – a fake data centre on Mars. We also managed to find Mars rover Curiosity’s tracks in Google Maps, and by downloading the full image, were able to find Curiosity herself.

We had a look at some strange patterns and other sights around Jiayuguan, China.

We had a look at how DigitalGlobe managed to transfer its vast archive of imagery (100 petabytes) to the cloud.

DigitalGlobe released imagery of the Mocoa Landslide in Colombia. We also had a look at a remarkably similar event, the Armero Tragedy, that occurred in 1984.

Ongoing Sri Lanka flooding visible in Sentinel-2 imagery

Sri Lanka is currently experiencing severe flooding across its south-western region, reportedly killing at least 122 people so far. We had a look at Sentinel-2 imagery and were impressed to find some very recent imagery from May 28th, 2017, already available on Amazon Web Services (AWS).

Below you can see the southern city of Matara surrounded by flood waters, as well as the muddy water streaming into the Indian Ocean.

The Canton, Texas Tornados with Sentinel-2 imagery

by Timothy Whitehead on May.29, 2017, under 3D Models, Argentina, Australia, Brazil, California, Denmark, England, Germany, Google Earth News, Google Earth Tips, Google Sky, Google maps, Hawaii, Indonesia, Ireland, Italy, Japan, Kenya, Mexico, Natural Landmarks, Netherlands, Sightseeing, Street Views, USA

On April 29th, 2017 a tornado tore through Canton, Texas leaving 5 dead and over 50 injured.

We had a look at the Sentinel-2 imagery of the region and we can see two tornado tracks across Canton:


Two tornado tracks near Canton, Texas.

There were tornadoes reported in nearby Eustace and Caney City. We suspect they are reports of the tornado shown on the left below.

Tornado tracks as far as we could trace them in Sentinel-2 imagery.


Zooming in on Canton, we can see how the track passed over several residential areas.

A section of the left (western) track shows a relatively straight right edge with curved tails coming off the left edge. We believe we can conclude from the shape that the tornado was rotating clockwise. We do not know which direction it was travelling (north or south).

Hopefully, we will see higher resolution DigitalGlobe imagery at a later date.

To see the relevant Sentinel-2 imagery in Google Earth, download this KML file. We have also included the locations of all US tornadoes of 2017 as listed on Wikipedia. Keep in mind that Wikipedia’s tornado locations are often far from accurate.

There have been a number of other strong tornadoes in May, but the relevant Sentinel-2 imagery is not yet available on AWS.
