Data

The data that is produced with this software can be directly accessed via the cloud using tools like DuckDB; see the tutorials and analytics other methods and latest instructions.

Global Coastal Transect System (GCTS)

Cross-shore coastal transects are essential to coastal monitoring, offering a consistent reference line to measure coastal change, while providing a robust foundation to map coastal characteristics and derive coastal statistics thereof.

The Global Coastal Transect System consists of more than 11 million cross-shore coastal transects uniformly spaced at 100-m intervals alongshore, for all OpenStreetMap coastlines that are longer than 5 kilometers.

# Download all transects located in the United States.
duckdb -c "COPY (SELECT * FROM 'az://coclico.blob.core.windows.net/gcts/release/2024-08-02/*.parquet' AS gcts WHERE gcts.country = 'US') TO 'United_States.parquet' (FORMAT 'PARQUET')"

# Download transects by bounding box.
duckdb -c "COPY (SELECT * FROM 'az://coclico.blob.core.windows.net/gcts/release/2024-08-02/*.parquet' AS gcts WHERE bbox.xmin <= 14.58 AND bbox.ymin <= -22.77 AND bbox.xmax >= 14.27 AND bbox.ymax >= -23.57) TO area_of_interest.parquet (FORMAT 'PARQUET')"

# Or, download the data in bulk using AZ CLI
az storage blob download-batch \
    --destination "./" \
    --source "gcts" \
    --pattern "release/2024-08-02/*.parquet" \
    --account-name coclico

Usage

More extensive installation and usage instructions will come when we build the documentation. For now, to run the tutorials, analytics or scripts clone the repository, install the environment using a package manager like miniconda. You may use Jupyter lab to explore the interactive content of the notebooks.

git clone https://TUDelft-CITG/coastpy.git
cd coastpy
mamba env create -f environment.yml
jupyter lab
