90. Fråga: Hämta satellitbildsdata efter geometri

Hämta statistik över vegetationsindex för valfri ad-hoc-geometri - ingen registrerad fältgräns krävs. Denna endpoint beräknar sammanfattande statistik för pixlar inom din geometri samtidigt som molniga pixlar ignoreras. För närvarande stöds av Sentinel2 (S2) , Landsat (L4/L5/L7/L8/L9) och Planet (PS) leverantörer.

Denna sida följer GeoPards API-mönster och autentisering som används över GraphQL-endpoints.

Vad du kan göra

• Fråga vegetationsindex för Point, MultiPoint, Polygon och MultiPolygon geometrier.

• Välj bildmaterial leverantörer: S2, L4, L5, L7, L8, L9, PS.

• Få datumstämplade resultat per förvärv med:

  • molnfria - andel av din geometri som är molnfri, intervall från 0 till 1, där 1 betyder helt molnfri.

  • value - statistik för det valda indexet beräknat endast på molnfria pixlar, inkluderar min, max, avg, mdn, var, std.

• Valfritt ange intervall array av indexvärdesintervall för att beräkna täckningsstatistik. När detta anges kommer svaret att innehålla ett intervall fält som visar vilken procent av området som faller inom varje angivet intervall.

  • Area som upptas av varje färg/intervall - baserat på indexvärde (lågt => högt)

  • Täcksprocent - 0..1 värde per intervall som representerar yta i procent

Stödda index

EVI2, NDVI, RVI, LAI, OSAVI, SAVI, GNDVI, IPVI, GCI, WDRVI, RCI, SBI, MCARI1. Indexdefinitioner följer GeoPards vegetationsindexkatalog som används i hela API:et.

Inmatningsparametrar

Fält	Typ	Obligatoriskt	Anteckningar
index	Enum (se ovan)	✅	Vegetationsindex att beräkna.
leverantörer	[Provider!]!	✅	Någon av S2, L4, L5, L7, L8, L9, PS.
startDate	String (ISO8601)	✅	Inkluderande start, t.ex. "2025-05-10T00:00:00.000Z".
endDate	String (ISO8601)	✅	Exklusivt slut eller inkluderande slut beroende på schema; matcha dina andra GeoPard-frågor.
geojson	String	✅	En strängifierad GeoJSON av typen Point / MultiPoint / Polygon / MultiPolygon (WGS84 [lon, lat]). Kom ihåg att escap:a citattecken inuti strängen.
intervall	[[Float!]!]	❌	Array av [min, max] par av indexvärdesintervall för att beräkna täckningsstatistik

Prestandaråd

• För Polygon/MultiPolygon-geometrier, håll datumintervallen snäva (~10–15 dagar) på grund av bearbetningstiden.

• Timeout: 30 s. Använd färre dagar och/eller färre leverantörer om du når gränsen.

• För Point/MultiPoint är större intervall vanligtvis okej (punkter är lätta).
