What is the Earth Engine?
Earth Engine is a platform for scientific analysis and visualization of geospatial datasets, with planetary-scale analysis capabilities.
It is hosts satellite imagery and stores it in a public data archive that includes historical earth images going back over 40 years.
Earth Engine uses for academic, non-profit, business and government. Now it’s available for commercial use and remains free for academic and research use.

How Earth Engine different from Google Earth?
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.
On the other hand, Earth Engine 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.
