Geospatial
It hosts decades of satellite and climate datasets, such as Landsat and Sentinel. Users write scripts in JavaScript or Python to compute change over time, such as forest loss or sea ice. Results export to maps and tables.
It is free for research and education, with commercial plans for business use.
QGIS and ArcGIS work with local data. Earth Engine suits climate scientists and geospatial analysts.
