Learn how to use this powerful tool to quickly and easily access and process aerial imagery
Google Earth Engine (GEE) for Remote Sensing applications is quickly becoming one of the most utilized tools in the scientific and decision-making community.
Remote Sensing is the science of capturing information about the earth’s surface using reflected or emitted energy collected by sensors mounted on satellites, aircraft or drones. Researchers from many disciplines have been using Remote Sensing in their research to better understand and respond to natural hazards, and to monitor land use and the effects of climate change.
If you have employed Remote Sensing in your research, you may have gone through a somewhat cumbersome workflow: downloading data from NASA's website, and then processing it on your own machine, which could be frustratingly slow due to the huge size of data files and hardware limitations. Google Earth Engine (GEE) (not to be confused with Google Earth) makes it easier and quicker to access and process satellite imagery. Also, it is designed with disciplinary researchers' needs in mind, not just remote sensing specialists' needs. Here is a GEE app example of Global Forest Change by the University of Maryland.

What is Google Earth Engine?
Google Earth Engine (not to be confused with Google Earth) allows anyone to access and process satellite imagery quickly and easily. Using a few lines of simple code, you can access images for a region, display a map, look for temporal or spatial trends, export data and statistics, and much more. Previously, remote sensing required downloading huge datasets and high computing power to process the data, but Google Earth Engine takes care of that by storing and processing 50+ years of earth observation data on Google’s servers.
