sentinelsat
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
sentinelsat -u <user> -p <password> -g <search_polygon.geojson> --sentinel 2 --cloud 30
and a powerful Python API.
from sentinelsat import SentinelAPI, read_geojson, geojson_to_wkt
api = SentinelAPI('user', 'password')
footprint = geojson_to_wkt(read_geojson('search_polygon.geojson'))
products = api.query(footprint,
producttype='SLC',
orbitdirection='ASCENDING')
api.download_all(products)
Documentation is published at http://sentinelsat.readthedocs.io/.
Installation
Install sentinelsat
through pip:
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
from sentinelsat import SentinelAPI, read_geojson, geojson_to_wkt
from datetime import date
# connect to the API
api = SentinelAPI('user', 'password', 'https://scihub.copernicus.eu/dhus')
# download single scene by known product id
api.download(<product_id>)
# search by polygon, time, and Hub query keywords
footprint = geojson_to_wkt(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.get_product_odata(<product_id>)
# Get the product's full metadata available on the server
api.get_product_odata(<product_id>, 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.
sentinelsat -u <user> -p <password> -g <geojson>
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.
sentinelsat -u <user> -p <password> -g <search_polygon.geojson> -s 20150101 -e 20151231 -d \
--producttype SLC -q "orbitdirection=Descending" \
--url "https://scihub.copernicus.eu/dhus"
Username, password and DHuS URL can also be set via environment variables for convenience.
# same result as query above
export DHUS_USER="<user>"
export DHUS_PASSWORD="<password>"
export DHUS_URL="https://scihub.copernicus.eu/dhus"
sentinelsat -g <search_polygon.geojson> -s 20150101 -e 20151231 -d \
--producttype SLC -q "orbitdirection=Descending"
Options
-u | --user | TEXT | Username [required] (or environment variable DHUS_USER) |
-p | --password | TEXT | Password [required] (or environment variable DHUS_PASSWORD) |
--url | TEXT | Define another API URL. Default URL is 'https://scihub.copernicus.eu/apihub/'. | |
-s | --start | TEXT | Start date of the query in the format YYYYMMDD. |
-e | --end | TEXT | End date of the query in the format YYYYMMDD. |
-g | --geometry | PATH | Search area geometry as GeoJSON file. |
--uuid | TEXT | Select a specific product UUID instead of a query. Multiple UUIDs can separated by commas. | |
--name | TEXT | Select specific product(s) by filename. Supports wildcards. | |
--sentinel | INT | Limit search to a Sentinel satellite (constellation). | |
--instrument | TEXT | Limit search to a specific instrument on a Sentinel satellite. | |
--producttype | TEXT | Limit search to a Sentinel product type. | |
-c | --cloud | INT | Maximum cloud cover in percent. (requires --sentinel to be 2 or 3) |
-o | --order-by | TEXT | Comma-separated list of keywords to order the result by. Prefix '-' for descending order. |
-l | --limit | INT | Maximum number of results to return. Defaults to no limit. |
-d | --download | Download all results of the query. | |
--path | PATH | Set the path where the files will be saved. | |
-q | --query | TEXT | Extra search keywords you want to use in the query. Separate keywords with comma. Example: 'producttype=GRD,polarisationmode=HH'. |
-f | --footprints | Create geojson file search_footprints.geojson with footprints of the query result. | |
--info | Display DHuS server information. | ||
--version | Show version number and exit. | ||
-h | --help | Show help message and exit. |
Tests
To run the tests on sentinelsat
:
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
export DHUS_USER=<username>
export DHUS_PASSWORD=<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:
git clone https://github.com/sentinelsat/sentinelsat.git
cd sentinelsat
pip install -e .[dev]
cd docs
make html
