90. Sorgu: Geometriye göre UyduGörüntüsü Verilerini al

Herhangi bir geçici geometrinin bitki örtüsü indeksi istatistiklerini al - kayıtlı bir saha sınırı gerekli değil. Bu uç nokta geometriniz içindeki pikseller için özet istatistikler hesaplar ve bulutlu pikselleri görmezden gelir. Şu anda destekleniyor Sentinel2 (S2) , Landsat (L4/L5/L7/L8/L9) ve Planet (PS) sağlayıcılarında.

Bu sayfa GeoPard’ın API kalıplarını takip eder ve kimlik doğrulama GraphQL uç noktalarında kullanılan ile aynıdır.

Yapabilecekleriniz

• Sorgu bitki örtüsü indeksleri için Point, MultiPoint, Polygon ve MultiPolygon geometrileri.

• Görüntülemeyi seçin sağlayıcıları: S2, L4, L5, L7, L8, L9, PS.

• Al tarih damgalı her edinime ait sonuçlar ile:

  • bulutsuz - geometrinizin bulutsuz olan kısmının kesri, 0 ile 1 arasında değer; 1 tamamen bulutsuz demektir.

  • value - seçilen indeks için istatistikler yalnızca bulutsuz piksellerde hesaplanır, içerir min, max, avg, mdn, var, std.

• İsteğe bağlı olarak sağlayın aralıklar kapsama istatistikleri hesaplamak için indeks değer aralıkları dizisi. Sağlandığında, yanıt her belirtilen aralığa düşen alan yüzdesini gösteren bir aralıklar alan alanı göstergesi içerecektir.

  • Her renk/aralığın kapladığı alan - indeks değerine göre (düşük => yüksek)

  • Kapsama yüzdesi - yüzey yüzdesini temsil eden her aralık için 0..1 değeri

Desteklenen indeksler

EVI2, NDVI, RVI, LAI, OSAVI, SAVI, GNDVI, IPVI, GCI, WDRVI, RCI, SBI, MCARI1. İndeks tanımları GeoPard’ın bitki örtüsü indeksi kataloğunu API genelinde kullanılanı takip eder.

Girdi parametreleri

Alan	Tür	Gerekli	Notlar
indeks	Enum (yukarıya bakın)	✅	Hesaplanacak bitki örtüsü indeksi.
sağlayıcıları	[Provider!]!	✅	Şunlardan herhangi biri S2, L4, L5, L7, L8, L9, PS.
startDate	String (ISO8601)	✅	Dahil başlangıç, örn. "2025-05-10T00:00:00.000Z".
endDate	String (ISO8601)	✅	Şemaya bağlı olarak hariç tutulmuş veya dahil son; diğer GeoPard sorgularınızla eşleştirin.
geojson	String	✅	Bir stringleştirilmiş GeoJSON türü Point / MultiPoint / Polygon / MultiPolygon (WGS84 [lon, lat]). Dizgenin içindeki tırnakları kaçırmayı unutmayın.
aralıklar	[[Float!]!]	❌	Aşağıdakilerin dizisi [min, max] kapsama istatistiklerini hesaplamak için indeks değer aralığı çiftleri

Performans rehberi

• Polygon/MultiPolygon geometrileri için tarih aralıklarını dar tutun (~10–15 gün) işlem süresi nedeniyle.

• Zaman aşımı: 30 s. Limite takılırsanız daha az gün ve/veya daha az sağlayıcı kullanın.

• Point/MultiPoint için daha geniş aralıklar genellikle sorun olmaz (noktalar hafiftir).
