Satelitska slika: obrezana po meji polja Na voljo je natančen (ne piksliran) izrez satelitske slike na podlagi določenih meja polja za različne poglede, kot so `RGB, NIR, EVI2, LAI, NDVI, GNDVI, IPVI, GCI, SAVI, OSAVI, NDWI, WDRVI, NDMI, MCARI`, itd. Vsaka SatelliteImage vsebuje `geoMaps` objekt, ki hrani podrobnosti o upodobitvi, kot so `url`, barvne kode, razredi in ime. Te podrobnosti se nahajajo v `polju` -> `atributu satelliteImages` -> `geoMaps` atributu. The `url` posebej se uporablja za prikaz zemljevidov kot WMS plast. Za ilustracijo so spodaj priloženi primeri izhoda za poglede NIR in WDRVI. ### Bližnji infrardeči (NIR), WDRVI in kontrast WDRVI ![NIR](https://29491374-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://29491374-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://29491374-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) Zahteva je v formatu [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:). ### Pojasnilo parametrov URL Kjer so vstopni atributi: 1. `VIEWPARAMS=uuid:` vsebuje `uuid` od "Field"; 2. `TIME=2020-07-22T17%3A50%3A22Z` ima podatke satelitske slike v formatu YYYY-MM-DDThh:mm:ssZ (URL kodirano) in je lociran v entiteti "FieldSatelliteImagery" s `acquisitionDate` atributom; 3. `BBOX=` vsebuje omejitveni okvir (url kodiran) polja "Field" v projekciji EPSG:3857; 4. `WIDTH=512` odseva izhodno velikost slike v piksljih (natančno število je pomembno le, če se uporablja kot sličica); 5. `geopardApiKey=` je povezan z možnostjo avtorizacije preko API ključa; 6. `LAYERS=sentinel2_wdrvi_and_field` odraža stil, atribut provider se nahaja v entiteti "FieldSatelliteImagery". Na voljo možnosti za Sentinel2 (`S2`) posnetke `LAYERS` so: `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` na voljo možnosti za Landsat8 (`L8, L9`) posnetke `LAYERS` so: `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` na voljo možnosti za Landsat4-7 (`L4, L5, L6, L7`) posnetke `LAYERS` so: `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`

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 dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.geopard.tech/geopard-tutorials/svn/api-dokumentacija/geo-koncne-tocke-za-dostop-do-prostorskih-podatkov/wms-pridobi-rastrske-slike-prostorskih-podatkovnih-slojev/16.-satelitska-slika-obrezana-po-meji-polja.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
