# 90. Spørring: Hent SatelliteImagery-data etter geometri Hent statistikk for vegetasjonsindekser for hvilken som helst ad-hoc-geometri - **ingen registrert åkergrense kreves**. Denne endepunkten beregner oppsummeringsstatistikk for piksler innenfor geometrien din mens **ignorerer skyete piksler**. Foreløpig støttet på **Sentinel2 (S2)** , **Landsat (L4/L5/L7/L8/L9)** og **Planet (PS)** leverandører. {% hint style="danger" %} Denne siden følger GeoPards API-mønstre og [autentisering](https://docs.geopard.tech/geopard-tutorials/api-docs/authorization-apikey-credentials-or-oauth-2.0) som brukes på tvers av GraphQL-endepunktene. {% endhint %} ## Hva du kan gjøre * Spørring **vegetasjonsindekser** for **Point, MultiPoint, Polygon og MultiPolygon** geometrier. * Velg bilder **leverandører**: `S2`, `L4`, `L5`, `L7`, `L8`, `L9`, `PS`. * Få **dato-stemplet** resultater per opptak med: * `skyfritt` - andel av geometrien din som er skyfri, verdiområde fra 0 til 1, der 1 betyr fullstendig skyfri. * `value` - statistikk for den valgte indeksen beregnet **kun** på skyfrie piksler, inkluderer `min`, `max`, `avg`, `mdn`, `var`, `std`. * Valgfritt oppgi **områder** array av indeksverdieranger for beregning av dekningsstatistikk. Når dette oppgis, vil svaret inkludere et `områder` felt som viser hvilken prosentandel av arealet som faller innenfor hver angitte rekkevidde. * **Areal opptatt av hver farge/rekkevidde** - basert på indeksverdi (lav => høy) * **Dekningsprosent** - 0..1 verdi per rekkevidde som representerer prosentandel av overflaten ## Støttede indekser `EVI2`, `NDVI`, `RVI`, `LAI`, `OSAVI`, `SAVI`, `GNDVI`, `IPVI`, `GCI`, `WDRVI`, `RCI`, `SBI`, `MCARI1`. Indeksdefinisjoner følger GeoPards [katalog over vegetasjonsindekser](https://docs.geopard.tech/geopard-tutorials/product-tour-web-app/satellite-monitoring/indices-for-crops-and-soils#vegetation-indices) som brukes gjennom API-et. ### Inndataparamertere
FeltTypePåkrevdNotater
indeksEnum (se ovenfor)✅Vegetasjonsindeks som skal beregnes.
leverandører[Provider!]!✅Hvilken som helst av S2, L4, L5, L7, L8, L9, PS.
startDatoString (ISO8601)✅Inklusiv start, f.eks. "2025-05-10T00:00:00.000Z".
sluttDatoString (ISO8601)✅Eksklusiv slutt eller inklusiv slutt avhengig av skjema; match dine andre GeoPard-spørringer.
geojsonString✅En stringified GeoJSON av typen Point / MultiPoint / Polygon / MultiPolygon (WGS84 [lon, lat]). Husk å escape anførselstegnene inne i strengen.
områder[[Float!]!]❌Array av [min, max] par av indeksverdieranger for beregning av dekningsstatistikk
## **Ytelsesråd** * For Polygon/MultiPolygon-geometrier, hold datointervaller korte (**\~10–15 dager**) på grunn av behandlingstid. * **Timeout:** 30 s. Bruk færre dager og/eller færre leverandører hvis du treffer grensen. * For Point/MultiPoint er større intervaller vanligvis greit (punkter er lettvektere). ## Responsskjema ```graphql

additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.geopard.tech/geopard-tutorials/nor/api-dokumentasjon/geopard-api-foresporsler-oversikt/90.-sporring-hent-satelliteimagery-data-etter-geometri.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
