Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.geopard.tech/geopard-tutorials/dnk/api-dokumentation/geo-endpoints-til-adgang-til-spatiale-data/wms-hent-rasterbilleder-af-spatiale-datalag/16.-satellitbillede-beskaret-efter-markgraense.md). # 16. Satellitbillede: beskåret efter markgrænse Et nøjagtigt (ikke pixeleret) udsnit af satellitbilledet baseret på den definerede markgrænse er tilgængeligt for forskellige visninger såsom `RGB, NIR, EVI2, LAI, NDVI, GNDVI, IPVI, GCI, SAVI, OSAVI, NDWI, WDRVI, NDMI, MCARI`, osv. Hvert SatelliteImage indeholder et `geoMaps` objekt der rummer renderingdetaljer som `url`, farvekoder, klasser og navn. Disse detaljer findes inden for `feltet` -> `satelliteImages` -> `geoMaps` attributten. `url` bruges specifikt til at vise kort som et WMS-lag. For at illustrere er outputeksempler for NIR- og WDRVI-visninger givet nedenfor. ### Nær-infrarød (NIR), WDRVI og WDRVI-kontrast ![NIR](https://1581835146-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FYICBELdyAXXebKAzfLOR%2Fuploads%2FBO5IUPWygVgPKpMAsela%2Fimage.png?alt=media\&token=23504b6c-df7c-460e-b1cd-b184fe86c575) ![WDRVI](https://1581835146-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FYICBELdyAXXebKAzfLOR%2Fuploads%2FWWNyxHuZj4eEkSrUPEN1%2Fimage.png?alt=media\&token=8cccb814-3eb8-4b55-b1eb-ff0609091f68) ![WDRVI Contrast](https://1581835146-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FYICBELdyAXXebKAzfLOR%2Fuploads%2F7f0VDnbb4I5kiw7OdDg5%2Fimage.png?alt=media\&token=1ccffb9a-88b3-431b-9c8d-703cb784a5e6) Forespørgselsformatet er [https://api.geopard.tech/geo/map/reflect?TRANSPARENT=true\&VIEWPARAMS=uuid:\\&TIME=2020-07-22T17%3A50%3A22Z\&BBOX=\\&LAYERS=sentinel2\_wdrvi\_and\_field\&SRS=EPSG%3A900913\&WIDTH=512\&geopardApiKey=\](https://api.geopard.tech/geo/map/reflect?TRANSPARENT=true\&VIEWPARAMS=uuid:). ### Forklaring af URL-parametrene Hvor inputattributterne er: 1. `VIEWPARAMS=uuid:` indeholder `uuid` af "Marken"; 2. `TIME=2020-07-22T17%3A50%3A22Z` har dataene for satellitbilledet i formatet YYYY-MM-DDThh:mm:ssZ (URL-enkodet) og placeret i enheden "FieldSatelliteImagery" med `acquisitionDate` attribut; 3. `BBOX=` indeholder begrænsningsboksen (url-kodet) for "Field" i EPSG:3857-projektion; 4. `WIDTH=512` angiver outputbilledets størrelse i pixels (det præcise antal er kun vigtigt, hvis det bruges som miniature); 5. `geopardApiKey=` er knyttet til autorisationsmuligheden via API-nøgle; 6. `LAYERS=sentinel2_wdrvi_and_field` afspejler stilen, provider-attributten placeret i enheden "FieldSatelliteImagery". De tilgængelige muligheder for Sentinel2 (`S2`) imagery `LAYERS` er: `sentinel2_ndvi_and_field` `sentinel2_evi2_and_field` `sentinel2_rgb_and_field` `sentinel2_gci_and_field` `sentinel2_lai_and_field` `sentinel2_nir_and_field` `sentinel2_osavi_and_field` `Sentinel2_wdrvi_and_field` de tilgængelige muligheder for Landsat8 (`L8, L9`) imagery `LAYERS` er: `landsat8_ndvi_and_field` `landsat8_evi2_and_field` `landsat8_rgb_and_field` `landsat8_gci_and_field` `landsat8_lai_and_field` `landsat8_nir_and_field` `landsat8_osavi_and_field` `landsat8_wdrvi_and_field` de tilgængelige muligheder for Landsat4-7 (`L4, L5, L6, L7`) imagery `LAYERS` er: `landsat4-7_ndvi_and_field` `landsat4-7_evi2_and_field` `landsat4-7_rgb_and_field` `Landsat4-7_gci_and_field` `landsat4-7_lai_and_field` `landsat4-7_nir_and_field` `landsat4-7_osavi_and_field` `landsat4-7_wdrvi_and_field`
--- # Agent Instructions This documentation is published with 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/dnk/api-dokumentation/geo-endpoints-til-adgang-til-spatiale-data/wms-hent-rasterbilleder-af-spatiale-datalag/16.-satellitbillede-beskaret-efter-markgraense.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.
