Last Saturday, on 17th June, a landslide in Greenland caused a tidal wave killing four people and injuring nine in the community of Nuugaatsiaq. Two other communities Igdlorssuit and Viaqornat were apparently affected. Read more about it on the Landslide Blog.

We love Landsat and Sentinel-2 imagery for their easy accessibility and global coverage, but they are rather low resolution at 10 m per pixel for Sentinel-2 and 15 m per pixel for Landsat. Commercial satellite imaging company Planet, now covers the globe with greater regularity and higher resolution (typically about 3 m per pixel) and for the US state of California, releases the imagery under creative commons licence within a couple of weeks of capture.

Thank you to GEB reader Dieter van Werkum for letting us know about a Google Earth quiz maker he has created. See here for a sample of what it can produce, and the source code is on Github. He has adapted it to work with the new web based Google Earth as well as Google Earth classic.

Thank you to GEB reader Adino for letting us know that the island nation of Malta is the latest country to get Street View. We also discovered that South Korea has also received expanded coverage.

We recently came across this article about a scientific study of the populations grey seals in the North Atlantic that used Google Earth imagery to do a census.

In January we created a simple KML converter that takes a KML file and produces a csv file that is easily opened with Microsoft Excel. Recently GEB reader David Kettle asked whether it would be possible to go both ways.

When looking through the latest imagery update in Google Earth, we came across some images in northern Uganda. They were captured by DigitalGlobe as part of their ‘FirstLook’ program and relate to the movement of refugees from South Sudan into Uganda. There is ongoing violence in South Sudan which has in turn created a famine in the region. The combination is causing many people to flee the country. According to Wikipedia, the refugee camp is named Bidi Bidi, and with over 270,000 residents is the largest refugee settlement in the world.

Mudslides in Argentina
In January, 2017, heavy rains in the northern Argentine province of Jujuy resulted in several mudslides that killed two women and injured at least five other people. Google has recently added some imagery captured soon after the event. As of this writing, the fresh imagery is only available in the default layer and has not yet been pushed to ‘historical imagery’.

The new web-based Google Earth is based on a completely new graphics engine. So, we wondered whether or not Google had implemented any compression algorithms or other mechanisms to reduce the amount of data that Google Earth needs to download. An example of such a mechanism is Google’s own Draco 3D compression library which they open sourced in January.

Google recently posted on their blog an article saying they have recently released Street View of the iconic Uluru, also known as Ayers Rock, Australia.
