Google Earth Engine is an online environment monitoring platform that makes available to the entire world a dynamic digital model of our planet that is updated daily. It stores petabytes of satellite data and allows high-performance tools to analyze and interpret this information that can then be visualized on a map, ranging from rainforest changes in the Amazon to water resources in the Congo.
