Sencast is a toolbox to download and derive water quality parameters from satellite images. It acts as a framework for the use a variety of processors such as Idepix, Polymer, Sen2Cor and Acolite. It supports ESA satellites Sentinel 2 and Sentinel 3 and USGS satellite Landsat 8.
It is developed and maintained by the SURF Remote Sensing group at Eawag.
Anaconda and Snap Desktop are required to install Sencast
git clone [email protected]:eawag-rs/sencast.git
conda env create -f ~/sencast/sencast.yml
Then create your environment file (use environments/example.ini as a template) and test your installation as follows:
cd ~/sencast
conda activate sencast
python main.py -t
This will output a log of which processors are functioning. After the above steps it is normal that only the image download functions. For installation of the processors refer to the full documentation below:
Full documentation is available at ReadTheDocs.
python main.py
| Parameter | Default | Description |
|---|---|---|
| -t --tests | False | run test processing to check setup |
| -x --delete_tests | False | delete previous test run |
| -p --parameters | Required | link to the parameters.ini file (required when not running tests) |
| -e --environment | ${machine-name}.ini | link to the environment.ini file |
| -d -–downloads | 1 | number of parallell downloads |
| -p --processors | 1 | number of parallell processors |
| -a --adapters | 1 | number of parallell adapters |

Manual installation of all the processors is challenging and can be simplified through the use of a docker container.
As this container contains non-open source code, the pre-build image is only available internally at Eawag. However, external parties can build the image
themselves by including docker_dependencies/polymer-v4.15.tar.gz in the repository.
Users should first ensure they have a functioning docker installation.
The docker image can be built using the following command:
docker build -t eawag/sencast:0.0.1 .
In order to test the setup is working the following command can be run which will output a report on the functioning of the processors. This must be run from inside the sencast repository.
The option -v /DIAS:/DIAS maps the input/ output folders to a location outside the container. This should be updated to
the appropriate location, e.g. -v /home/user/DIAS:/DIAS
docker run -v /DIAS:/DIAS -v $(pwd):/sencast --rm -it eawag/sencast:0.0.1 -e docker.ini -t
-e name of the environment file in sencast/environments
-t flag to indicate a test should be run
In order to run a parameters file it can be passed to the command as follows using the -p flag.
docker run -v /DIAS:/DIAS -v $(pwd):/sencast --rm -it eawag/sencast:0.0.1 -e docker.ini -p example.ini
-p name of the parameter file in sencast/parameters
Sometimes it is desirable to interact directly with the container, this can be achieved with the following command:
docker run -v /DIAS:/DIAS -v $(pwd):/sencast --rm -it --entrypoint /bin/bash eawag/sencast:0.0.1
