# 90. Lekérdezés: Műholdképadatok lekérése geometria alapján Szerezz be növényzeti index statisztikákat bármilyen ad hoc geometriához - **nem szükséges regisztrált parcellahatár**. Ez a végpont összegző statisztikákat számol a geometriádon belüli pixelekre, miközben **figyelmen kívül hagyja a felhős pixeleket**. Jelenleg támogatott a **Sentinel2 (S2)** , **Landsat (L4/L5/L7/L8/L9)** és **Planet (PS)** szolgáltatókon. {% hint style="danger" %} Ez az oldal követi a GeoPard API mintáit és [hitelesítést](https://docs.geopard.tech/geopard-tutorials/api-docs/authorization-apikey-credentials-or-oauth-2.0) amit a GraphQL végpontoknál használnak. {% endhint %} ## Mit tehetsz * Lekérdezés **növényzeti indexek** számára **Point, MultiPoint, Polygon és MultiPolygon** geometriák. * Válassz képfeldolgozó **szolgáltatókat**: `S2`, `L4`, `L5`, `L7`, `L8`, `L9`, `PS`. * Kapj **dátummal ellátott** eredményeket minden felvételre a következőkkel: * `felhőmentesség` - a geometriádnak a felhőmentes részének aránya, 0–1 tartományban, ahol az 1 teljesen felhőmentest jelent. * `érték` - a kiválasztott indexre számított statisztikák **csak** felhőmentes pixeleken, tartalmaz `min`, `max`, `avg`, `mdn`, `var`, `std`. * Opcionálisan add meg **tartományokat** indexérték-tartományok tömbje a lefedettségi statisztikák számításához. Megadva a válasz tartalmazni fog egy `tartományokat` mezőt, amely megmutatja, hogy a terület hány százaléka esik az egyes megadott tartományokba. * **Az egyes színek/tartományok által elfoglalt terület** - az indexérték alapján (alacsony => magas) * **Lefedettség százalékban** - 0..1 érték tartományonként, ami a felszín százalékát jelenti ## Támogatott indexek `EVI2`, `NDVI`, `RVI`, `LAI`, `OSAVI`, `SAVI`, `GNDVI`, `IPVI`, `GCI`, `WDRVI`, `RCI`, `SBI`, `MCARI1`. Az indexdefiníciók a GeoPard [növényzeti index katalógusát](https://docs.geopard.tech/geopard-tutorials/product-tour-web-app/satellite-monitoring/indices-for-crops-and-soils#vegetation-indices) használják az API egészében. ### Bemeneti paraméterek
MezőTípusKötelezőMegjegyzések
indexEnum (lásd fent)✅A számolandó növényzeti index.
szolgáltatókat[Provider!]!✅Bármely a S2, L4, L5, L7, L8, L9, PS.
startDateString (ISO8601)✅Kezdő dátum befoglaló, pl. "2025-05-10T00:00:00.000Z".
endDateString (ISO8601)✅Kizárólagos vagy befoglaló vég a séma függvényében; egyezzen meg a többi GeoPard lekérdezéseddel.
geojsonString✅Egy stringgé alakított GeoJSON típusa Point / MultiPoint / Polygon / MultiPolygon (WGS84 [lon, lat]). Ne felejtsd el escape-elni a string belsejében lévő idézőjeleket.
tartományokat[[Float!]!]❌Tömb [min, max] párok az indexérték-tartományokhoz a lefedettségi statisztikák számításához
## **Teljesítményre vonatkozó útmutató** * Poligon/MultiPolygon geometriák esetén tartsd szűken a dátumtartományokat (**\~10–15 nap**) a feldolgozási idő miatt. * **Timeout:** 30 mp. Használj kevesebb napot és/vagy kevesebb szolgáltatót, ha eléri a határt. * Point/MultiPoint esetén általában nagyobb időtartományok is megfelelnek (a pontok könnyűek). ## Válasz alakja ```graphql graphqlMásolásSzerkeszt{ geojson # a bemeneti geometriád visszhangja (stringgé alakított) data: [ { uuid # raszter jelenet azonosító provider # S2, L8, L9, ... acquisitionDate # ISO8601 cloudfree # 0..1 felhőmentes területrész value: { index # pl.

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/hu/api-dokumentacio/geopard-api-keresek-attekintese/90.-lekerdezes-muholdkepadatok-lekerese-geometria-alapjan.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.
