Terrapattern is a fun prototype that lets you search satellite imagery simply by clicking on a map. For example, you can click on a tennis court, and through machine learning, the application looks for similar areas.
Sedimentary geologist Zoltan Sylvester downloaded Landsat data using Earth Explorer and strung together images of the Ucayali River to see the changes over thirty years.
Thanks to the Landsat program and Google Earth Engine, it is possible now to explore how the surface of the Earth has been changing through the last thirty years or so. Besides the obvious issues of interest, like changes in vegetation, the spread of cities, and the melting of glaciers, it is also possible to look at how rivers change their courses through time.
Excellence is hard to keep quite.

Great tool to see the differences between different projections, with the differences visible for the latitudes too.
Get the right projection for a chosen extent, be it equal-area, conformal or equidistant.
Wow, pretty impressive panoramic views, with multiple functions, like time lapse, archive, panning, …
Interesting, simple display of migration trends, in total numbers and as percentage of the population. NYT
Very interesting to see how countries “loose” size while dragging them over the earth. Due to the usual global projection, Greenland for example looks really huge, but, when compared correctly in size with African countries around the equator, it looks rather shrinked….
Looking for some tool to collaborate together on a text-document? PiratePad could do it…

The Global Peace Index measures the state of peace in 162 countries according to 23 indicators that gauge the absence of violence or the fear of violence. It is produced annually by the Institute for Economics and Peace.
This year the results show that globally, levels of peace remained stable over the last year, however are still lower than in 2008.
Since last year, 81 countries have become more peaceful, while 78 have deteriorated.
Many countries in Europe, the world’s most peaceful region, have reached historically high levels of peace. 15 of the 20 most peaceful countries are in Europe.
Due to an increase in civil unrest and terrorist activity, the Middle East and North Africa is now the world’s least peaceful region for the first time since the Index began.
Globally the intensity of internal armed conflict has increased dramatically, with the number of people killed in conflicts rising over 3.5 times from 49,000 in 2010 to 180,000 in 2014.
The economic impact of violence reached a total of US$14.3 trillion or 13.4% of global GDP last year.
The most peaceful countries are Iceland, Denmark and Austria. The countries that made the biggest improvements in peace over the last year, generally benefited from the ending of wars with neighbours and involvement in external conflict. The biggest improvers were: Guinea-Bissau, Cote d’Ivoire, Egypt and Benin.
Syria remains the world’s least peaceful country, followed by Iraq and Afghanistan. The country that suffered the most severe deterioration in peace was Libya, which now ranks 149th of 162 countries. Ukraine suffered the second largest deterioration: following a popular revolution which brought down the administration of Viktor Yanukovych, Russia moved to destabilise the country, meaning it scored poorly on organised conflict indicators.
‘2014 was marked by contradictory trends: on the one hand many countries in the OECD achieved historically high levels of peace, while on the other, strife-torn nations, especially in the Middle East, became more violent. This is a real concern as these conflict become even more intractable they spread terrorism to other states.’
