Google Earth Engine is a cloud platform that combines a large catalogue of satellite imagery and geospatial datasets with tools for analysing them at scale. Users work through a web-based code editor or through the Earth Engine API, which is available in Python and JavaScript. It is aimed at scientists, researchers and developers and is delivered entirely as a cloud service, so no analysis software needs to be installed locally.
Earth Engine is provided by Google LLC, a company organised under the laws of Delaware and headquartered in Mountain View, California, and it runs on Google Cloud infrastructure. Because of this US ownership and jurisdiction, US authorities, for example under the CLOUD Act, can reach the provider regardless of where the data is stored. The product page does not state where datasets or user data are kept, so European organisations with data residency requirements should check the contractual terms before use. For sensitive or sovereign workloads, self-hosted open-source tools such as SNAP or QGIS are the European alternatives.
