    • Add these to both credentials_earthdata.yaml and .netrc file
  • Copernicus Dataspace - https://dataspace.copernicus.eu/
    • Add these to credentials_copernicus.yaml
  • AWS credentials
    • Add these to credentials_aws.yaml to enable DEM download and upload to desired destination
• run the setup script to build the docker container

sh setup.sh

Instructions

• set scene, path and processing details in config.yaml
• run process scripts

sh run_process.sh

Mount the correct directories in docker

WARNING - current setup mounts the /data folder inside the container. This assumes all of the paths where data will be accessed are in the /data folder (e.g. /data/scenes, /data/pyrosar ...). If data is stored across multiple folders without a common root folder (such as /data), the run_process.sh script will need to be changed to mount these folders to /data within the container. The workflow also mounts the local aws files in the container.

For example, if scenes are downloaded to /my/path/scenes, and other folders are all in /data the run_process.sh script will look like:

docker run -v /data:/data -v ${PWD}:/app/ -v $HOME/.aws:/root/.aws -v /my/path/scenes:/my/path/scenes -it pyrosar
