2017–2019 Land Cover Map of Pyrénées-Atlantiques

This archive contains a land cover map of the French department Pyrénées-Atlantiques (64) based on Sentinel-2 satellite images performed with iota² chain (https://framagit.org/iota2-project/iota2/). The algorithm used is a Random Forest performed on all L3A images of the 2017–2019 time period. The training and validation data that we used is a combination of Corine Land Cover (Copernicus), BD TOPO (IGN), Registre Parcellaire Graphique (IGN) and self performed photo-interpretation. 

It is part of a work in progress and the comparison between different time series and preprocessing levels still need to be completed. Also, the lack of training data for the photo-interpreted classes 'landes basses' (low heath shrublands),  'landes hautes' (high heath shrublands) and 'landes à dynamique de boisement' (young-growth forest) leads to significantly lower results for these classes. They are still massively confused with other land covers like grasslands and broadleaf mature forests. Have a look at the confusion matrix provided in the archive. It is performed on a different dataset than the one used for training. We are looking forward to improving these results in the upcoming months. 

The archive also contains a text file with the nomenclature and the Qgis style layer.
