Dotaz: Získání dat satelitního snímkování podle geometrie Získejte statistiky indexu vegetace pro libovolnou ad-hoc geometrii - **není vyžadován registrovaný hranice pole**. Tento endpoint vypočítá souhrnné statistiky pro pixely uvnitř vaší geometrie zatímco **ignoruje zamračené pixely**. V současnosti podporováno na **Sentinel2 (S2)** , **Landsat (L4/L5/L7/L8/L9)** a **Planet (PS)** poskytovatelích. {% hint style="danger" %} Tato stránka následuje vzory API GeoPard a [autentizaci](https://docs.geopard.tech/geopard-tutorials/api-docs/authorization-apikey-credentials-or-oauth-2.0) používanou napříč GraphQL endpointy. {% endhint %} ## Co můžete dělat * Dotazovat se **indexy vegetace** pro **geometrie Point, MultiPoint, Polygon a MultiPolygon.** geometrie. * Vyberte snímky **poskytovatele**: `S2`, `L4`, `L5`, `L7`, `L8`, `L9`, `PS`. * Získejte **s časovou značkou** výsledky za pořízení se: * `bez mraků` - podíl vaší geometrie, který je bez mraků, rozsah hodnot od 0 do 1, kde 1 znamená plně bez mraků. * `value` - statistiky pro vybraný index vypočtené **pouze** na pixelech bez mraků, zahrnuje `min`, `max`, `avg`, `mdn`, `var`, `std`. * Volitelně poskytněte **rozsahy** pole rozsahů hodnot indexu pro výpočet pokryvnostních statistik. Pokud je poskytnuto, odpověď bude obsahovat `rozsahy` pole ukazující, jaké procento plochy spadá do každého specifikovaného rozsahu. * **Plocha obsazená každou barvou/rozsahem** - založeno na hodnotě indexu (nízké => vysoké) * **Procento pokrytí** - hodnota 0..1 za rozsah představující procento plochy ## Podporované indexy `EVI2`, `NDVI`, `RVI`, `LAI`, `OSAVI`, `SAVI`, `GNDVI`, `IPVI`, `GCI`, `WDRVI`, `RCI`, `SBI`, `MCARI1`. Definice indexů následují GeoPardův [katalog indexů vegetace](https://docs.geopard.tech/geopard-tutorials/product-tour-web-app/satellite-monitoring/indices-for-crops-and-soils#vegetation-indices) používaný v celém API. ### Vstupní parametry
PoleTypPovinnéPoznámky
indexEnum (viz výše)✅Index vegetace k výpočtu.
poskytovatele[Provider!]!✅Jakýkoli z S2, L4, L5, L7, L8, L9, PS.
startDateString (ISO8601)✅Inkluzivní začátek, např. "2025-05-10T00:00:00.000Z".
endDateString (ISO8601)✅Exkluzivní konec nebo inkluzivní konec v závislosti na schématu; slad'te to s ostatními dotazy GeoPard.
geojsonString✅A stringifikovaný GeoJSON typu Point / MultiPoint / Polygon / MultiPolygon (WGS84 [lon, lat]). Nezapomeňte uvnitř řetězce escapovat uvozovky.

## **Doporučení pro výkon** * Pro geometrie Polygon/MultiPolygon držte časová okna úzká (**\~10–15 dní**) kvůli době zpracování. * **Timeout:** 30 s. Použijte méně dní a/nebo méně poskytovatelů pokud narazíte na limit. * Pro Point/MultiPoint jsou obvykle větší intervaly v pořádku (body jsou nenáročné). ## Tvar odpovědi ```graphql graphqlCopyEdit{ geojson # echo vaše vstupní geometrie (stringifikovaná) data: [ { uuid # id rastrové scény provider # S2, L8, L9, ... acquisitionDate # ISO8601 cloudfree # 0..1 podíl plochy bez mraků value: { index # např.

GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.geopard.tech/geopard-tutorials/cze/dokumentace-api/prehled-pozadavku-geopard-api/90.-dotaz-ziskani-dat-satelitniho-snimkovani-podle-geometrie.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
