Google Earth Engine

A planetary-scale platform for environmental data & analysis

Google Earth Engine brings together the world's satellite imagery—trillions of scientific measurements dating back more than 25 years—and makes it available online with tools for scientists, independent researchers, and nations to mine this massive warehouse of data to detect changes, map trends and quantify differences to the earth's surface.

Using this new tool, we've already begun helping scientists develop applications for detecting deforestation and mapping land use trends, and have started working with individual countries to develop their own applications.
