DSWX-SAR

Dynamic Surface Water Extent from Synthetic Aperture Radar

Installation

Download the Source Code

Download the source code and change working directory to cloned repository:

git clone https://github.com/opera-adt/DSWX-SAR.git

Standard Installation

Install dependencies (installation via conda is recommended):

conda install --file docker/requirements.txt
conda install -c conda-forge --file docker/requirements_forge.txt

Install via setup.py:

python setup.py install
python setup.py clean

Note: Installation via pip is not currently recommended due to an issue with the osgeo and gdal dependency.

OR update environment path to run DSWX-SAR:

export DSWX_SAR_HOME=$PWD
export PYTHONPATH=${PYTHONPATH}:${DSWX_SAR_HOME}/src
export PATH=${PATH}:${DSWX_SAR_HOME}/bin

Process data sets; use a runconfig file to specify the location of the dataset, the output directory, parameters, etc.

dswx_s1.py <path to runconfig file>

Note: Only Sentinel-1 data is currently supported.

A default runconfig file can be found: DSWX-SAR > src > dswx_sar > defaults > dswx_s1.yaml. This file can be copied and modified for your needs. Note: The runconfig must meet this schema: DSWX-SAR > src > dswx_sar > schemas > dswx_s1.yaml.

Alternate Installation: Docker Image

Skip the standard installation process above.

Then, from inside the cloned repository, build the Docker image: (This will automatically run the workflow tests.)

./build_docker_image.sh

Load the Docker container image onto your computer:

docker load -i docker/dockerimg_dswx_s1_final_1.0.tar

See DSWx-SAR Science Algorithm Software (SAS) User Guide for instructions on processing via Docker.
