Bridging Earth Observation data and Machine Learning in Python
Extracting valuable information from satellite imagery is challenging primarily due to large amounts of data. On top of that, there is a big lack of techniques allowing for automatic detection and extraction of complex patterns in such spatiotemporal data. Join us to see how we leverage
eo-learn to obtain meaningful information from satellite data with just a few lines of Python code.
The availability of open Earth observation (EO) data through the Copernicus and Landsat programs, as well as plethora of commercially available satellite imagery, represents an unprecedented resource for many EO applications, ranging from ocean and land use/land cover monitoring to disaster control, emergency services and humanitarian relief. Large amounts of such spatiotemporal data call for tools that are able to automatically extract complex patterns embedded inside.
eo-learn is a collection of open source Python packages that have been developed to seamlessly access and process spatio-temporal satellite imagery in a timely and automatic manner. It makes the extraction of valuable information from satellite imagery as easy as defining a sequence of operations to be performed on satellite imagery. It also encourages collaboration --- the tasks and workflows can be shared, thus allowing for community-driven ways to exploit EO data.
eo-learn library acts as a bridge between the Earth Observation (EO)/Remote Sensing (RS) field and the Python ecosystem for data science and machine learning. It lowers the entry barrier to the field of RS for non-experts and simultaneously brings the state-of-the-art tools for computer vision, machine learning, and deep learning existing in Python ecosystem to remote sensing experts.
During the workshop we will introduce the
eo-learn framework, show examples of tasks dealing with retrieving the EO data (e.g. Sentinel-2, Sentinel-1, DEM), processing it, adding non-EO data (e.g. labels) to the dataset etc. and finally build the whole pipeline to run such workflow for larger areas, thus preparing the data for ML algorithms.
Follow the workshop with just your browser?
You can use the "launch binder" link above at the top of this README, which will launch a notebook instance on Binder with all required libraries installed.
Work on your own computer?
In case you have some time on your hands and would like to work through the exercises on your machine, the minimal requirements are
At the moment the recommended way is using a virtual environment (
python3.6 -m venv eo-learn-workshop) or
pipenv Installing with
conda might prove problematic. On Linux it is recommended to install system packages from CI build instructions first.
Alternatively, create a new environment for this tutorial using the provided environment.yml file:
conda env create --name eo-learn-workshop --file environment.yml conda activate eo-learn-workshop
Running with your Sentinel Hub account
It is possible to run the tutorial using your own Sentinel-Hub credentials. In order to do that, there are a few instructions you have to follow:
- if you don't have a Sentinel Hub account, you can create a trial account for free here
- once you have the account set up, login to Sentinel Hub Configurator. By default you will already have the default confoguration with an instance ID (alpha-numeric code of length 36). For these examples it is recommended that you create a new configuration ("Add new configuration") and set the configuration to be based on
eo-learn workshop template. The configuration already contains all layers used in this workshop.
