Sentinelsat makes searching, downloading and retrieving the metadata of

Sentinel
_ satellite images from the
Copernicus Open Access Hub 
_ easy.

It offers an easy-to-use command line interface

.. code-block:: bash

sentinelsat -u -p --location Berlin --sentinel 2 --cloud 30 --start NOW-1MONTH

and a powerful Python API.

.. code-block:: python

from sentinelsat import SentinelAPI, readgeojson, geojsonto_wkt

api = SentinelAPI('user', 'password') footprint = geojsontowkt(readgeojson('searchpolygon.geojson')) products = api.query(footprint, producttype='SLC', orbitdirection='ASCENDING', limit=10) api.download_all(products)

Documentation is published at http://sentinelsat.readthedocs.io/.

Installation

Install

sentinelsat
through pip:

.. code-block:: bash

pip install sentinelsat

Usage

Sentinelsat provides a Python API and a command line interface to search, download and retrieve the metadata for Sentinel products.

Python Library

.. code-block:: python

from sentinelsat import SentinelAPI, readgeojson, geojsonto_wkt from datetime import date

# connect to the API api = SentinelAPI('user', 'password', 'https://apihub.copernicus.eu/apihub')

# download single scene by known product id api.download()

# search by polygon, time, and Hub query keywords footprint = geojsontowkt(read_geojson('map.geojson')) products = api.query(footprint, date = ('20151219', date(2015, 12, 29)), platformname = 'Sentinel-2', cloudcoverpercentage = (0, 30))

# download all results from the search api.download_all(products)

# GeoJSON FeatureCollection containing footprints and metadata of the scenes api.to_geojson(products)

# GeoPandas GeoDataFrame with the metadata of the scenes and the footprints as geometries api.to_geodataframe(products)

# Get basic information about the product: its title, file size, MD5 sum, date, footprint and # its download url api.getproductodata()

# Get the product's full metadata available on the server api.getproductodata(, full=True)

Valid search query keywords can be found at the

Copernicus Open Access Hub documentation
_.

Command Line Interface

A basic search query consists of a search area geometry as well as the username and password to access the Copernicus Open Access Hub.

.. code-block:: bash

sentinelsat -u -p -g

Search areas are provided as GeoJSON files, which can be created with

QGIS 
_ or
geojson.io 
_. If you do not specify a start and end date only products published in the last 24 hours will be queried.

Example ^^^^^^^

Search and download all Sentinel-1 scenes of type SLC, in descending orbit, for the year 2015.

.. code-block:: bash

sentinelsat -u -p -g -s 20150101 -e 20151231 -d \ --producttype SLC -q "orbitdirection=Descending" \ --url "https://apihub.copernicus.eu/apihub"

Username, password and DHuS URL can also be set via environment variables for convenience.

.. code-block:: bash

# same result as query above export DHUSUSER="" export DHUSPASSWORD="" export DHUS_URL="https://apihub.copernicus.eu/apihub"

sentinelsat -g -s 20150101 -e 20151231 -d \ --producttype SLC -q "orbitdirection=Descending"

Tests

To run the tests on

sentinelsat
:

.. code-block:: bash

git clone https://github.com/sentinelsat/sentinelsat.git
cd sentinelsat
pip install -e .[dev]
pytest -v

By default, prerecorded responses to Copernicus Open Access Hub queries are used to not be affected by its downtime. To allow the tests to run actual queries against the Copernicus Open Access Hub set the environment variables

.. code-block:: bash

export DHUS_USER=
export DHUS_PASSWORD=

and add

--disable-vcr
to
pytest
arguments. To update the recordings use
--vcr-record
with
once
,
new_episodes
or
all
. See
vcrpy docs 
_ for details.

Documentation

To build the documentation:

.. code-block:: bash

git clone https://github.com/sentinelsat/sentinelsat.git
cd sentinelsat
pip install -e .[dev]
cd docs
make html

The full documentation is also published at http://sentinelsat.readthedocs.io/.
