What is CoastSeg?
Coastseg stands for Coastal Segmentation, it is an interactive jupyter notebook for downloading satellite imagery with CoastSat and applying Doodleverse/Zoo image segmentation models to satellite imagery. CoastSeg provides an interactive interface for drawing Regions of Interest (ROIs) on a map, downloading satellite imagery, loading geojson files, extracting shorelines from satellite imagery, and much more. In a nutshell, it is ...
- ... an easy way to download time-series of cloud-masked and post-processed satellite imagery anywhere in the world
- ... a mapping extension for CoastSat using Segmentation Zoo models.
- ... an interactive interface to download satellite imagery using CoastSat from Google Earth Engine
- ... an interactive interface for extracting shorelines from satellite imagery
- ... an interactive interface to apply segmentation models to satellite imagery
In more detail, CoastSeg represents the following advances in satellite-derived shoreline workflows:
- An emulation of the CoastSat methodology for defining a shoreline extraction project, image downloading, shoreline extraction, shoreline filtering, and tide correction, all within a single jupyter notebook that can be accessed online
- A pip-installable package for CoastSat workflows
- Use of concurrency for image downloads from Google Earth Engine
- A faster and more convenient API-based methodology for tidal height estimation, using pyTMD
- An initial implementation of an alternative shoreline mapping workflow using Zoo models from the Doodleverse
- A conda environment that can work on secure networks
- Script-based data wrangling utilities
- Hyperparameter experimentation and tracking using an organizational workflow idea called ‘Sessions’
- Supporting databases for transects, reference shorelines, beach slopes, and other useful metadata variables
- A deep-learning based shoreline extraction workflow (still in development)
Version 1 is now stable, and we have a lot of planned new features for version 2.
- Create ROIs(regions of interest) along the coast and automatically load shorelines on the map.
- Use Google Earth Engine to automatically download satellite imagery for each ROI clicked on the map.
- Coastseg can automatically extract shorelines from downloaded satellite imagery.
Installation Instructions
We recommend that you use Windows 10, Windows 11, or Ubuntu Linux. Mac users, please see here
In order to use Coastseg you need to install Python packages in an environment. We recommend you use Anaconda or Miniconda to install the python packages in an environment for Coastseg.
After you install miniconda/Anaconda on your PC, open the Anaconda prompt or Terminal in Mac and Linux and use the cd
command (change directory) to go the folder where you have downloaded the Coastseg repository.
Install from conda-forge
- Create an miniconda/Anaconda environment and Activate it
- This command creates an anaconda environment named
coastseg
and installspython 3.10
in it.conda create --name coastseg python=3.10 -y conda activate coastseg
-
Install coastseg
conda install -c conda-forge coastseg
-
(Optional) Install Optional Dependencies
- Only install these dependencies if you plan to use CoastSeg's zoo workflow notebook.
pip install tensorflow pip install transformers
Install from Pypi
- Create an miniconda/Anaconda environment
- This command creates an anaconda environment named
coastseg
and installspython 3.10
in it.conda create --name coastseg python=3.10 -y
-
Activate your conda environment
conda activate coastseg
- If you have successfully activated coastseg you should see that your terminal's command line prompt should now start with
(coastseg)
.
- Install Conda Dependencies
- CoastSeg requires
jupyterlab
andgeopandas
to function properly so they will be installed in thecoastseg
environment. - Geopandas has GDAL as a dependency so its best to install it with conda.
- Make sure to install geopandas from the
conda-forge
channel to ensure you get the latest version. - Make sure to install both jupyterlab and geopandas from the conda forge channel to avoid dependency conflicts
conda install -c conda-forge geopandas -y
- CoastSeg requires
- Install the CoastSeg from PyPi
pip install coastseg
- Uninstall the h5py installed by pip and reinstall with conda-forge
pip install jsonschema==4.19.0
is a temporary command you have to run until issue https://github.com/stac-utils/pystac/issues/1214 is resolved
pip install jsonschema==4.19.0 --user pip uninstall h5py -y conda install -c conda-forge h5py -y
Having Installation Errors?
Use the command conda clean --all
to clean old packages from your anaconda base environment. Ensure you are not in your coastseg environment or any other environment by running conda deactivate
, to deactivate any environment you're in before running conda clean --all
. It is recommended that you have Anaconda prompt (terminal for Mac and Linux) open as an administrator before you attempt to install coastseg
again.
Conda Clean Steps
conda deactivate
conda clean --all

pip install jsonschema==4.19.0 --user
Option 2: Update to a Specific Version
- Install CoastSeg from PyPi
- If you need a specific version of CoastSeg, use this command:
- Replace with the desired version number (e.g., 1.1.26).
pip install coastseg==<version>
- Don't worry if you see the warning message below. This is normal
"ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts."
- Install jsonschema
- This is necessary to run coastseg in a jupyter notebook.
pip install jsonschema==4.19.0 --user
