Geedim
======

.. description_start

Geedim provides a Python API and command line toolkit for exporting and cloud masking Google Earth Engine (GEE) imagery.  Images and Image collections can be exported to:

- GeoTIFF file
- NumPy array
- Xarray Dataset / DataArray
- Google Cloud platforms

And cloud masking is supported on:

- Landsat 4-9 `collection 2 <https://developers.google.com/earth-engine/datasets/catalog/landsat>`__ images
- Sentinel-2 `TOA <https://developers.google.com/earth-engine/datasets/catalog/COPERNICUS_S2_HARMONIZED>`__ and `surface reflectance <https://developers.google.com/earth-engine/datasets/catalog/COPERNICUS_S2_SR_HARMONIZED>`__ images

.. description_end

.. install_start

Installation
------------

To install from PyPI:

.. code:: shell

   pip install geedim

To install from conda-forge:

.. code:: shell

   conda install -c conda-forge geedim

To support exporting to Xarray, use ``pip install geedim[xarray]`` or ``conda install -c conda-forge geedim xarray`` instead.

A registered Google Cloud project is required for `access to Earth Engine <https://developers.google.com/earth-engine/guides/access#get_access_to_earth_engine>`__.  Once installation and registration is done, Earth Engine should be authenticated:

.. code:: shell

   earthengine authenticate

.. install_end

Examples
--------

API
~~~

Geedim provides access to its functionality through the ``gd`` accessor on the ``ee.Image`` and ``ee.ImageCollection`` `GEE <https://github.com/google/earthengine-api>`__ classes.  This example exports a 6 month cloud-free composite of Sentinel-2 surface reflectance imagery to a GeoTIFF file:

.. code:: python

    import ee

    # import geedim to enable accessors
    import geedim  # noqa: F401

    ee.Initialize()

    # filter collection based on cloud-free portion etc.
    region = ee.Geometry.Rectangle(24.35, -33.75, 24.45, -33.65)
    coll = ee.ImageCollection('COPERNICUS/S2_SR_HARMONIZED')
    filt_coll = coll.gd.filter(
        '2021-10-01', '2022-04-01', region=region, cloudless_portion=60
    )

    # print image properties
    print(filt_coll.gd.schemaTable)
    print(filt_coll.gd.propertiesTable)

    # create a cloud-free composite & download
    comp_im = filt_coll.gd.composite('median')
    prep_im = comp_im.gd.prepareForExport(
        crs='EPSG:3857', region=region, scale=10, dtype='uint16'
    )
    prep_im.gd.toGeoTIFF('s2_comp.tif')


Command line interface
~~~~~~~~~~~~~~~~~~~~~~

Much of the API functionality can also be accessed on the command line with ``geedim`` and its sub-commands.  This repeats the API example, exporting a 6-month cloud-free composite of Sentinel-2 surface reflectance imagery to a GeoTIFF file:

.. code:: shell

    geedim search -c COPERNICUS/S2_SR_HARMONIZED -s 2024-10-01 -e 2025-04-01 -b 24.35 -33.75 24.45 -33.65 -cp 60 composite -cm median download -c EPSG:3857 -r - -s 10 -dt uint16
