E:earth_africa:dal notebooks

This is a collection of example notebooks showcasting the capabilities of E:earth_africa:dal (Earth Observation Data Analysis Library).

The notebook "Sentinel-2 crop growing conditions" is the fully-reproducible example highlighted in

Graf, L.V, et al. (2022): EOdal: An Open-Source Python Package for Large Scale Agricultural Research Using Earth Observation and Gridded Environmental Data. Computers & Electronics in Agriculture, 203. https://doi.org/10.1016/j.compag.2022.107487

using the open-access Sentinel-2 collection on Microsoft Planetary Computer (no authentication required).

Further resources are available showing the general capacities of E:earth_africa:dal and further Sentinel-2 data handling in a fully reproducible manner.

Available Notebooks

• General

  • Load Images
  • Introduction to the Mapper class

  • Crop Growing Conditions
  • Field Parcel Extraction
  • Zonal Statistics of Field Parcels
  • Sentinel-2 Long Time Series Data to 4-D Numpy Array
  • Green Leaf Area Index Retrieval from Sentinel-2 Imagery

Getting started

E:earth_africa:dal can be installed from PyPI

pip install eodal

or get the latest source code version from Github by running

pip install git+https://github.com/EOA-team/eodal

Furthermore, a step-by-step guide shows you how to run the notebooks in a Docker container that can be found below.

Step-by-Step Guide

Install Docker

Install Docker on your machine. An installation guide to get Docker running on your system can be found here. We strongly recommend to use Docker to run the notebooks in a JupyterLab environment to avoid any dependency problems (especially with rasterio).

Start Docker

Once the docker daemon is running (on linux systems by running, e.g., sudo service docker start) build the container first using

docker-compose build

and start the service then by

docker-compose up -d

Finally, open your browser and go to (0.0.0.0:8888 or localhost:8888) to access the Jupyter server login page. The token is docker.

Now, you can re-run all Notebooks.
