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.
