Google Earth Engine

Google Earth Engine (GEE) is a powerful web-platform for cloud-based processing of remote sensing data on large scales. It brings together the world’s satellite imagery — trillions of scientific measurements dating back almost 40 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 on the Earth’s surface. Applications include detecting deforestation, classifying land cover, estimating forest biomass and carbon, and mapping the world’s roadless areas. The advantage lies in its remarkable computation speed, as processing is outsourced to Google servers. The platform provides a variety of constantly updated data sets, so no download of raw imagery is required. One of GEE’s tools, the Earth Engine Code Editor, is a web-based integrated development environment which facilitates developing complex geospatial workflows.

Gorelick et al. (2017) write in the 2017 Remote Sensing of the Environment article:

“Google Earth Engine is a cloud-based platform for planetary-scale geospatial analysis that brings Google’s massive computational capabilities to bear on a variety of high-impact societal issues including deforestation, drought, disaster, disease, food security, water management, climate monitoring and environmental protection.”
