STAC API - Item Search を使って FOSS4G 2022 Japan の会場がある荒川区を含むデータを検索してみます。

sankichi92/shikuchoson-boundaries を使って荒川区（行政区域コード: 13118）の行政区域界の GeoJSON を取得します。

In [4]:
import requests

arakawaku = requests.get('https://shikuchoson-boundaries.sankichi.app/13118.geojson').json()
arakawaku['bbox']

 35.754855171429085]

2022年10月に観測された荒川区を含む sentinel-s2-l2a-cogs のデータを検索します。

In [5]:
results = client.search(

以上、STAC API - Item Search による地球観測衛星データの簡単な検索でした。

もっと複雑な検索も可能で、詳細は各ドキュメントを参照してください。

  • STAC API - Item Search Specification
  • PySTAC Client

また、ここでは検索までしか紹介しませんが、検索で得られたデータを使って様々なことができます。
より高度な利用方法については https://stacindex.org/learn のチュートリアルなどを参照してみてください。
