EuroCropsML

Ready-to-use benchmark dataset for few-shot crop type classification using Sentinel-2 imagery.

Part of the PreTrainAppEO ("Pre-Training Applicability in Earth Observation") research project.

EuroCropsML is a pre-processed and ready-to-use machine learning dataset for crop type classification of agricultural parcels in Europe. It consists of a total of 706,683 multi-class labeled data points with a total of 176 distinct classes. Each data point contains an annual time series of per parcel median pixel values of Sentinel-2 L1C reflectance data for the year 2021. The dataset is based on Version 9 of EuroCrops, an open-source collection of remote sensing reference data.

For EuroCropsML, we acquired and aggregated data for the following countries:

Country	Total number of datapoints	Number of distinct classes
Estonia	175,906	127
Latvia	431,143	103
Portugal	99,634	79

The distribution of class labels differs substantially between the regions of Estonia, Latvia, and Portugal. This makes transferring knowledge gained in one region to another region quite challenging, especially if only few labeled data points are available. Therefore, this dataset is particularly suited to explore transfer-learning methods for few-shot crop type classification.

The data acquisition, aggregation, and pre-processing steps are schematically illustrated below. A more detailed description is given in the dataset section of our documentation.

Getting Started

eurocropsml is a Python package hosted on PyPI.

Installation

The recommended installation method is pip-installing into a virtual environment:

$ python -Im pip install eurocropsml

Usage Guide

The quickest way to interact with the eurocropsml package and get started is to use the EuroCropsML dataset is via the provided command-line interface (CLI).

For example, to get help on available commands and options, use

$ eurocropsml-cli --help

To show the currently used (default) configuration for the eurocropsml dataset CLI, use

$ eurocropsml-cli datasets eurocrops config

To download the EuroCropsML dataset as currently configured, use

$ eurocropsml-cli datasets eurocrops download

Alternatively, the dataset can also be manually downloaded from our Zenodo repository.

A comprehensive documentation of the CLI can be found in the CLI Reference section of our documentation.

For a complete example use-case demonstrating the ready-to-use EuroCropsML dataset in action, please refer to the project's associated official repository for benchmarking meta-learning algorithms.

Project Information

The eurocropsml code repository is released under the MIT License. Its documentation lives at Read the Docs, the code on GitHub and the latest release can by found on PyPI. It is tested on Python 3.10+.

If you would like to contribute to eurocropsml you are most welcome. We have written a short guide to help you get started.

Background

The EuroCropsML dataset and associated eurocropsml code repository are provided and developed as part of the joint PretrainAppEO research project by the chair of Remote Sensing Technology at Technical University Munich and dida.

The goal of the project is to investigate methods that rely on the approach of pre-training and fine-tuning machine learning models in order to improve generalizability for various standard applications in Earth observation and remote sensing.

The ready-to-use EuroCopsML dataset is developed for the purpose of improving and benchmarking few-shot crop type classification methods.

EuroCropsML is based on Version 9 of EuroCrops, an open-source collection of remote sensing reference data for agriculture from countries of the European Union.
