OpenEO_ODC_Driver

OpenEO processing engine written in Python based on OpenDataCube, Xarray and Dask.

Installation

Step 1: Clone the repository

git clone https://github.com/SARScripts/openeo_odc_driver.git
cd openeo_odc_driver

Step 2: Prepare the python environment

New ad-hoc conda environment:

conda env create -f environment.yml
conda activate openeo_odc

Step 3:

Modify the code with your system's details:

1. In odc_backend.py you have to insert the datacube-explorer address and the OpenDatcube config file path:

DATACUBE_EXPLORER_ENDPOINT = "http://0.0.0.0:9000"
OPENDATACUBE_CONFIG_FILE = ""

2. In odc_wrapper.py you have to insert the path of the OpenDataCube config file datacube.conf:

OPENDATACUBE_CONFIG_FILE = ""

3. In openeo_odc_driver.py you have to insert the Dask Scheduler address and the tmp folder to write output files:

DASK_SCHEDULER_ADDRESS = ''
TMP_FOLDER_PATH        = '' # Has to be accessible from all the Dask workers

If the environment creation step fails please create a Python 3.8 environment environment with the following libraries: datacube, gdal, xarray, rioxarray, dask, numpy, scipy, opencv and their dependencies.

Step 4: Start the web server:

gunicorn -c gunicorn.conf.py odc_backend:app
