Earth Observation Data Access Gateway
Project description
eodag
=====
EODAG (Earth Observation Data Access Gateway) is a command line tool and a plugin-oriented Python framework for searching,
aggregating results and downloading remote sensed images while offering a unified API for data access regardless of the
data provider. The EODAG SDK is structured around three functions:
* List product types: list of supported products and their description
* Search products (by product type) : searches products according to the search criteria provided
* Download products : download product “as is"
EODAG is developed in Python. It is structured according to a modular plugin architecture, easily extensible and able to
integrate new data providers. Three types of plugins compose the tool:
* Catalog search plugins, responsible for searching data (OpenSearch, CSW, ...), building paths, retrieving quicklook,
combining results
* Download plugins, allowing to download and retrieve data locally (via FTP, HTTP, ..), always with the same directory
organization
* Authentication plugins, which are used to authenticate the user on the external services used (JSON Token, Basic Auth, OAUTH, ...).
Read `the documentation <https://eodag.readthedocs.io/en/latest/>`_ for more insights.
Installation
============
EODAG is on `PyPI <https://pypi.org/project/eodag/>`_::
python -m pip install eodag
Usage
=====
Command line interface
----------------------
Create a configuration file from the :download:`template <user_conf_template.yml>` provided with the repository, filling
in your credentials as expected by each provider (note that this configuration file is required by now. However, this
will change in the future).
Then you can start playing with it:
* To search for products and crunch the results of the search::
eodag search \
--conf my_conf.yml \
--geometry 1 43 2 44 \
--startTimeFromAscendingNode 2018-01-01 \
--completionTimeFromAscendingNode 2018-01-31 \
--cloudCover 20 \
--productType S2_MSI_L1C
--cruncher FilterLatestIntersect \
--storage my_search.geojson
The request above search for product types `S2_MSI_L1C` and will crunch the result using cruncher `FilterLatestIntersect`
and storing the overall result to `my_search.geojson`.
You can pass arguments to a cruncher on the command line by doing this (example with using `FilterOverlap` cruncher
which takes `minimum_overlap` as argument)::
eodag search -f my_conf.yml -b 1 43 2 44 -s 2018-01-01 -e 2018-01-31 -p S2_MSI_L1C \
--cruncher FilterOverlap \
--cruncher-args FilterOverlap minimum_overlap 10
The request above means : "Give me all the products of type `S2_MSI_L1C`, use `FilterOverlap` to keep only those products
that are contained in the bbox I gave you, or whom spatial extent overlaps at least 10% (`minimum_overlap`) of the surface
of this bbox"
* To download the result of a previous call to `search`::
eodag download --conf my_conf.yml --search-results my_search.geojson
* To list all available product types and supported providers::
eodag list
* To list available product types on a specified supported provider::
eodag list -p airbus-ds
* To see all the available options and commands::
eodag --help
* To print log messages, add `-v` to `eodag` master command. e.g. `eodag -v list`. The more `v` given (up to 3), the more
verbose the tool is.
Python API
----------
Example usage for interacting with the api in your Python code:
.. code-block:: python
from eodag import SatImagesAPI
dag = SatImagesAPI(user_conf_file_path='/path/to/user/conf.yaml')
product_type = 'S2_MSI_L1C'
footprint = {'lonmin': 1, 'latmin': 43.5, 'lonmax': 2, 'latmax': 44}
start, end = '2018-01-01', '2018-01-31'
search_results = dag.search(
product_type,
geometry=footprint,
startTimeFromAscendingNode=start,
completionTimeFromAscendingNode=end,
)
product_paths = dag.download_all(search_results)
for path in product_paths:
print('Downloaded : {}'.format(path))
Contribute
==========
If you intend to contribute to eodag source code::
git clone https://bitbucket.org/geostorm/eodag.git
cd eodag
python -m pip intall -r requirements-dev.txt
To run the default test suite (which excludes end-to-end tests)::
tox
To only run end-to-end test::
tox -- tests.test_end_to_end
To run the entire tests (units, integraton and end-to-end)::
tox -- tests eodag
