Google Earth Engine (GEE)
Overview
Google Earth Engine (GEE) is a cloud-based platform for planetary-scale environmental data analysis, providing access to a multi-petabyte catalog of satellite imagery and geospatial datasets. GEE enables large-scale analysis without downloading data or managing infrastructure.
Key Concepts
Data Catalog contains petabytes of satellite imagery and geospatial data. Code Editor is a web-based IDE for writing analysis scripts. Image is a raster dataset with bands and metadata. ImageCollection is a stack of images (time series). Feature is a vector geometry with properties. FeatureCollection is a collection of Features. Reducer aggregates data (mean, sum, histogram).

| Landsat | 50+ years of imagery |
| Sentinel-2 | 10m multispectral |
| MODIS | Daily global coverage |
| SRTM | Global elevation |
| NLCD | US land cover |
Programming
