This repository contains Jupyter Notebooks and Python functions dedicated to the processing, analysis, and classification in Local Climate Zones (LCZ) of hyperspectral PRISMA and multispectral Sentinel-2 imagery.

The first two Notebooks are dedicated to data pre-processing. They allow the user to prepare Sentinel-2 and PRISMA data for the next processing and analysis stages. The remaining Notebooks are meant to explore, analyse, and classify ready-to-use data.

The repository is part of the results of the research activity carried out in the framework of the LCZ-ODC project in collaboration between Politecnico di Milano (Dipartimento di Ingegneria Civile e Ambientale) and Italian Space Agency (ASI), agreement n.
2022-30-HH.0. It represents the official repository linked to the following scientific paper:

Preprocessing Notebooks

  • 1 - S2_Preprocessing.ipynb: Reads and mosaics the Sentinel-2 tiles covering the area of interest, clips the mosaicked Sentinel-2 image to the extent of a reference PRISMA image, and exports the image to GeoTIFF.
  • 2 - PRISMA_S2_coregistration.ipynb: Coregisters the PRISMA image with the pre-processed Sentinel-2 image using the GeFolki algorithm; allows for the display and coregistration of both hyperspectral and panchromatic bands; exports the original and coregistered PRISMA images in GeoTIFF format and displays coregistration quality.
