1. Introduction to Google Earth Engine
Google Earth Engine is a cloud-computing platform for satellite imagery and other Earth observation data. Google Earth Engine combines petabyte-scale catalogs of satellite imagery and geospatial datasets with planetary-level analysis capabilities. Scientists, researchers, and developers use Earth Engine to detect changes in the Earth's surface, map trends, and quantify differences. Earth Engine is now available for commercial use and remains free for academic and research use.
In general, in Google Earth Engine, we can obtain more than three decades of historical imagery and scientific data sets, and the data is still being expanded and updated every day. On this platform, we can use the provided data to perform various spatial analysis operations, which can be roughly understood as the web-side implementation of cloud spatial database + ArcGIS and ENVI software functions, but its functions are far more than that, and it can also be implemented on the web-based The end-to-end code editor for rapid interactive algorithm development, access to PB-level data, remote sensing research, natural resource management and many other functions. The official address is:
