CPAZMAL: Cryosphere PAZ satellite MAchine Learning

CPAZMAL: Cryosphere PAZ satellite MAchine Learning The aim of this dataset is to serve as a foundation for machine learning in multi-class classification, specifically in mountainous regions. It comprises descending images acquired by the PAZ X-band satellite, focusing on the Mont Blanc region during the period from January 2020 to November 2021, totaling 56 acquisitions. The time series is divided into two sub-sections: From January 2020 to 8th January 2021 included: dual polarisation HH and HV, After 8th January 2021: single polarisation HH. The datas are divided into 8 classes: Hanging Glacier (HAG) Ice Aperon (ICA) Ablation area Accumulation area Rock Plain Forest City In each classe, between 4 to 10 groups or distinct areas, where their complete description (position, aspect, elevation, ...) can be found in the desc_topo_areas.png file We provide code that directly extracts temporal or spatial datasets, consisting of homogeneous windows paired with respective labels. # Request and save data into hdf5 file rqtemp = "classe in ['ICA','HAG','ABL','ACC','FOR','CIT','ROC','PLA'] & date < '2021-01-01'" cdlf = Dataset_tiff2hdf5 ( path_to_folder_extracted, different_group=True, n_jobs=1, outpath="path_to_dataset.h5", extension="temporal" ) cdlf.extract_data(rqtemp, polarisation="HH", winsize=7, save=True) # Load the previously extracted data set ( x, y, gr, org, _, ) = load_h5(path_to_dataset.h5) An example of how to use it can be found at Github.
