What Google Earth Engine Actually Is (and What It's Capable Of)
Start with the basics Satellites take pictures of the Earth constantly. Some take pictures of the same spot every single day. Over decades, this adds up to an enormous amount of imagery: what a forest looked like ten years ago versus today, how a city has grown, how a lake has shrunk. The problem is that this imagery is huge. We are talking about more data than a normal computer could ever…
Google Earth Engine is a powerful tool that enables anyone to analyze decades of satellite imagery using Google's computing power, without the need to download massive amounts of data to their own machines. With over 50 petabytes of data, including Landsat, Sentinel, MODIS, rainfall, climate, elevation, and nighttime images, Earth Engine allows users to track changes in the environment, such as deforestation, urban expansion, and drought.
By simply selecting an area on the map and asking a question about how it has changed over time, users can generate insights ranging from agriculture predictions to damage assessments after natural disasters. In 2026, Google introduced a tiered access system for commercial users, but the core functionality remains free for most users, democratizing access to satellite data for researchers, journalists, and businesses alike.
