Google has unveiled an online technology that allows scientists and researchers to track and measure changes to the environment using 25 years worth of satellite data. Google Earth Engine, introduced during climate talks in Cancun, utilizes “trillions of scientific measurements” collected by NASA’s
LANDSAT satellite, the company said. Google is already working on applications for tracking deforestation and mapping land use trends, including the creation of the most comprehensive scale map of Mexico’s forest and water resources ever made.
