How to use STAC

Install

pip install pystac-client

Connect and search

Open a connection to the eodc STAC API and search for items by collection, bounding box, and time range:

import pystac_client

stac_url = "https://stac.eodc.eu/api/v1"

eodc = pystac_client.Client.open(stac_url)

found = eodc.search(
    collections=["SENTINEL1_GRD"],
    bbox=[7.9, 48.9, 8, 49],
    datetime="2021-07-01/2021-07-15"
)

for item in found.items():
    print(item.id, item.datetime)

Step by step:

1. pystac_client.Client.open(stac_url) — connects to the eodc STAC API. No authentication required for public collections.

2. eodc.search(collections=...) — filters by collection name. Browse available collections at https://stac.eodc.eu/api/v1/collections.

3. bbox — spatial filter as [west, south, east, north] in WGS84 decimal degrees.

4. datetime — temporal filter as an ISO 8601 interval (start/end). Single dates are also accepted.

5. found.items() — iterates over matching STAC items. Each item contains metadata and links to the actual data assets.

Next steps

• Load assets into xarray using odc-stac — see the Load Data with Xarray notebook.

• See the Data Discovery notebook for a full worked example of searching and browsing collections.
