1. Detect glacial lake outlines from Sentinel-1 and Sentinel-2 data (2016-2025) using OBIA
2. Detect glacial lake outlines from Landsat data (1985-2015) using OBIA
3. Build a vector data cube using the glacial lake outlines

The contents of the scripts folder including scripts and environment.

Script to create lake outlines of the Jökulsárlón glacial lake (2016-2025) based on the method by Dabiri et al 2021. The script uses Sentinel-1 and Sentinel-2.

Script to create lake outlines of the Jökulsárlón glacial lake (1985-2015) based on the method by Dabiri et al 2021. The script uses Landsat 5-8 and ArcticDEM V4.

Notebook to create a vector data cube with the glacial lake outlines obtained with OBIA.

Loading the created VDC and using it for querying and zonal statistics.

not important A script from the beginning of the project.

Python translation of the original computational notebook created by Lorena Abad.

Preliminary data required for the scripts, and the glacial lake outlines (large files such as TIFs are not loaded here)

conda env create -f env.yaml

conda activate glacial_lakes

python -m ipykernel install --user --name glacial_lakes --display-name "glacial_lakes"

Copy the template and set your local project root:

cp config_template.py config.py

Then open config.py and set ROOT_DIR to your local project path.

Important: Manually review the lake outlines produced by notebooks 1 and 2 before running notebook 3.
