stactools is a command line tool and library for working with STAC.
It is based on PySTAC.
This is the core stactools repository, which provides a basic command line interface (CLI) and API for working with STAC catalogs.
There are a suite of packages available in other repositories for working with a variety of datasets and for doing more complicated oprations on STAC data.
See packages for more information.
To install the latest stable version:
> pip install stactoolsTo install the latest pre release:
> pip install stactools --preFrom source repository:
> git clone https://github.com/stac-utils/stactools.git
> cd stactools
> pip install .To download the Docker image from the registry:
> docker pull ghcr.io/stac-utils/stactools:latest> stac --help> docker run --rm ghcr.io/stac-utils/stactools:latest --helpSee the documentation page for the latest docs.
stactools is comprised of many other sub-packages that provide library and CLI functionality.
Officially supported packages are hosted in the Github stactools-packages organization, and other subpackages may be available from other sources.
Below is a list of officially supported packages and their current build status.
Each package can be installed via pip install stactools-{package}, e.g. pip install stactools-landsat.
Third-party packages can be installed in the same way, or, if they are not on PyPI, directly from the source repository, e.g. pip install /path/to/my/code/stactools-greatdata.
These extend the stac command line utility to provide additional funcionality.
| name | description | build status |
|---|---|---|
| stactools-browse | Launch stac-browser against a local catalog |  |
These are designed to work with specific types of geospatial data.
| name | data type | build status |
|---|---|---|
| stactools-aster | ASTER | |
| stactools-cgls_lc100 | Copernicus Global Land Cover Layers |  |
| stactools-corine | CORINE Land Cover |  |
| stactools-landsat | USGS LANDSAT |  |
| stactools-naip | USDA National Agriculture Imagery Program |  |
| stactools-planet | Planet |  |
| stactools-sentinel2 | Sentinel-2 |  |
| stactools-threedep | USGS 3D Elevation Program (formerly the National Elevation Dataset or NED) |  |
Some packages require environments with more complex environments than can be set up just through pip.
For example, the stactools.aster package uses rasterio functionality that required a GDAL enabled with the HDF4 format.
Because of this, it's recommended to utilize docker or conda to ensure a consistent environment.
Build the container with:
> docker/build
Once the container is built, you can run the scripts/ scripts inside a docker console by running:
> docker/console
A complete build and test can be run with:
> docker/cibuild
It is recommended to do a Docker CI build before submitting a pull request to ensure your changes will (likely) pass Github's CI.
In scenarios where you want to run scripts in docker/ but don't want to run the build, images can be downloaded via the pull script:
> docker/pull
Run a Juypter notebook:
> docker/notebook
conda is a useful tool for managing dependencies, both binary and Python-based.
If you have conda installed, you can create a new environment for stactools development by running the following command from the top-level directory in this repo:
> conda env create -f environment.yml
Then activate the stactools environment:
> conda activate stactools
Finally, install stactools in editable mode and all development requirements:
> pip install -e .
> pip install -r requirements-dev.txt
If not using docker or conda, it's recommended to use virtualenv to keep isolate the python environment used to develop stactools.
See virtualenv documentation for more detailed information, but as a shortcut here's some quick steps:
- Make sure virtualenv is installed
- Run
virtualenv venv - Activate the virtualenv with
source venv/bin/activate
You can run the CLI through docker by running
> docker/stac --help
or in the local environment with
> scripts/stac --help
Unit tests are in the tests folder. To run unit tests, use unittest:
> python -m unittest discover tests
To run linters, code formatters, and test suites all together, use test:
> ./docker/test
or
> ./scripts/test
The test script also runs lint and code quality checks.
Run a Juypter notebook:
> scripts/notebook
To build and serve the docs, all of the requirements must be installed with scripts/update.
Make sure Pandoc is installed.
Also make sure sphinx is available, which should be installed with requirements-dev.txt.
You can also run the following in the docker container using
> docker/console
To build the docs, you can use make html, and to build the docs and start a server that watches for changes, use make livehtml:
> cd docs
> make html
> make livehtml
If using make livehtml, once the server starts, navigate to http://localhost:8000 to see the docs.
Use 'make' without arguments to see a list of available commands.
To create a new stactools package, use the stactools package template.
stactools utilizes Python's namespace packages to provide a suite of tools all under the stactools namespace.
If you would like your package to be considered for inclusion as a core stactools package, please open an issue on this repository with a link to your package repository.
