Sentinel-2 Batch Download Tool for HSNB

This tool provides a rudimentary web GUI to query Sentinel-2 satellite imagery for a custom bounding box and time span which can then be downloaded as a single ZIP file. It was developed by the datacube team at EORC for agricultural scientists at HSNB.

Note that s2-batch-download.py is a standalone script that you can run directly in Python after editing the config in its first few lines, while server-worker.py is intended to be run as a daemon in a Docker container and accepts jobs via the web GUI it serves.

Setup

Prerequisites

You'll need Node.js and Docker.

Get the code

Clone this repo.

Build the web UI

cd /path/to/repo
cd ui
npm install
npm run build

This will create a dist folder within the ui folder, from where the static files are served that form the website that end users actually see.

Create an output directory

cd /path/to/repo
mkdir jobs

Or let it point wherever it is convenient for you (lots of gigabytes will be written there).

Prepare Docker

Add to your docker-compose.yml:

hsnb:
  build:
    context: ./hsnb
  container_name: hsnb
  volumes:
  - ./hsnb/jobs:/home/hsnb/jobs
  networks:
    - caddy

This assumes that you cloned the repo into a folder called hsnb within the same folder as your docker-compose.yml. And it also assumes that you have a Docker network called caddy where a web server does reverse proxying. The volumes section links the jobs folder in the actual file system (the path on the left of the colon) to the jobs folder in the container's file system (the path on the right of the colon).

Tell your webserver (if applicable)

Add to your Caddyfile (via sudo nano /etc/caddy/Caddyfile):

hsnb.eo2cube.org {
        reverse_proxy hsnb:8765
}

And update the Caddy config with docker exec -w /etc/caddy caddy caddy reload (assuming the Caddy webserver is running in a Docker container called caddy).

Start it

Then finally:

docker compose build hsnb
docker compose up hsnb
