Google Earth Engine (GEE) es una plataforma gratis en la nube que esta diseñada para el análisis de datos espaciales a una escala planetaria que incorpora las capacidades computacionales masivas de Google. Esta plataforma integrada está diseñada para potenciar no solo a los científicos tradicionales de teledetección, sino también a una audiencia mucho mas amplia que carece de capacidad técnica necesaria para utilizar supercomputadoras tradicionales o recursos de computación en la nube de productos básicos a gran escala.

rgee::ee_install want to store the environment variables: EARTHENGINE_PYTHON
and EARTHENGINE_ENV in your .Renviron file to use the Python path:
C:\Users\Junior\AppData\Local\r-miniconda\envs\rgee\python.exe in future sessions.
Would you like to continues? [Y/n]:Y
3. The Environment Variable 'EARTHENGINE_PYTHON=C:\Users\Junior\AppData\Local\r-miniconda\envs\rgee\python.exe'
was stored in the .Renviron file. Remember that you
could remove EARTHENGINE_PYTHON and EARTHENGINE_ENV using
rgee::ee_clean_pyenv().
4. Installing the earthengine-api. Running:
reticulate::py_install(packages = 'earthengine-api', envname = 'C:/Users/Junior/AppData/Local/r-miniconda/envs/rgee')
Well done! rgee was successfully set up in your system.
You need restart R to see changes. After doing that, we recommend
run ee_check() to perform a full check of all non-R rgee dependencies.
Do you want restart your R session?
1: yes
