Google Earth Engine brings together satellite imagery from the last 40 years, and allows users to quickly analyse the data online using a set of online clickable algorithms. It aims to make the vast amount of satellite imagery available online more easily accessible and understandable, since much satellite imagery is either difficult to access, or requires considerable preparation and expensive software to analyse.
A global high-resolution (30m) dataset of forest cover for the year 2000, and deforestation between 2000 and 2013 is also freely available through the Google Earth Engine. Other applications have included the visualisation of roadless areas.
Data visualisation and analysis is open for non-commercial use to everyone who signs an evaluation agreement. However some aspects, such as downloading some raw data, is only available to members of their trusted tester programme.
