Google Earth Engine (Gorelick et al., 2017) is a cloud computing platform designed for planetary-scale environmental data analysis that only can be accessed via the Earth Engine code editor, third-party web apps, and the JavaScript and Python client libraries. rgee is a non-official client library for R that uses reticulate to wrap the Earth Engine Python API and provide R users with a familiar interface, rapid development features, and flexibility to analyze data using open-source, R third-party packages.
The package implements and supports:
Earth Engine Module
Install or set all rgee dependencies
Check non-R dependencies
Clean non-R dependencies
Session management
Transform an R Date to an EE Date or vice versa
Create Interactive visualization Maps
Image download
Vector download
Generic download
Assets management
Upload raster
Upload vector
Upload generic
Extract values
Helper functions
Utils functions
Interface to main Earth Engine module. Provides access to top level classes and functions as well as sub-modules (e.g. ee$Image, ee$FeatureCollection$first, etc.).
