Introduction to Google Earth Engine (GEE) - AulaGEO

Get started with geospatial data by applying the JavaScript programming language

Google Earth Engine is a platform for scientific analysis and visualization of geospatial datasets, for academic, non-profit, business and government users.

Google Earth Engine hosts satellite imagery and stores it in a public data archive that includes historical earth images going back more than forty years. The images, ingested on a daily basis, are then made available for global-scale data mining.

Earth Engine also provides APIs and other tools to enable the analysis of large datasets.

Google Earth enables you to travel, explore, and learn about the world by interacting with a virtual globe. You can view satellite imagery, maps, terrain, 3D buildings, and much more.

Earth Engine, on the other hand, is a tool for analyzing geospatial information. You can analyze forest and water coverage, land use change, or assess the health of agricultural fields, among many other possible analyses.

While the two tools rely on some of the same data, only some of Google Earth's imagery and data is available for analysis in Earth Engine.
