![]() If three channels are needed it’s already 600 MB of data. If the image is stored with 16-bits precision without compression that’s 1,600,000,000 bits or 200 MB for each channel. Sentinel-2 data is a good example as it consists of multi-spectral satellite images with up to 10-meter spatial resolution and an orbit revisit period of 5 days considering both Sentinel-2A and Sentinel-2B satellites.Īs an example, if you are studying a region of 100 x 100 km and your data spatial resolution is 10 meters, your image size will be 10,000 x 10,000 pixels. In other words, it is a service freely available that combines a large set of global datasets that often would be impossible to handle without a super-computer. ![]() “Google Earth Engine combines a multi-petabyte catalog of satellite imagery and geospatial datasets with planetary-scale analysis capabilities and makes it available for scientists, researchers, and developers to detect changes, map trends, and quantify differences on the Earth’s surface.” ![]() According to the main webpage of Google Earth Engine:
