Converting Emodnet

This script takes one or more EMODnet tiles and converts them to a cloud optimised GeoTiff, validates the new file, and uploads to JASMIN.

---

Prerequisites

Before running the script you will need the following environment variables set:

• JASMIN_TOKEN
• JASMIN_SECRET
• JASMIN_API_URL

INPUT_PATH, OUTPUT_PATH & BUCKET_NAME within the script will likely need changing too.

Running the script without upload

If you'd like to download the default E3 and E4 tiles and create the combined COG file without uploading to JASMIN then run the script run.sh.

Running the script manually

To run script, run the folowing commands:

conda env update -f environment.yml
conda activate imfe_convert_emodnet

python process_emodnet -i  input_dir -o output_dir -b bucket name

• input_dir should be replaced with the path to directory containing the .nc file of data.
• output_dir should be replaced with the path to directory containing the COG file.
• bucket_name is the name of the bucket in JASMIN to write to

Running the script without uploading

To generate the STAC catalog without uploading use the command: python process_emodnet -i input_dir -o output_dir -b bucket name --skip-upload.
