Lineage Information | Sentinel-2 Global Mosaic palvelun osat (https://usermanual.readthedocs.io/en/latest/) ovat: Valitun alueen ja ajanjakson Sentinel-2 kuvien valinta. Kuvien ilmakehäkorjaus Sen2cor-algoritmilla. Mosaiikin pikselin arvoksi valitaan ajanjakson kuvien pikseleitä se joka poikkeaa vähiten muista. Tiilittäisen mosaiikin tuottaminen valituilla kanavilla, pikselikoolla ja koordinaattijärjestelmällä. Tiilittäiset mosaiikit ladataan paikalliselle tietokoneelle jolla tehdään jälkiprosessointivaihe, eli tiilet yhdistetään kanavittaisiksi mosaiikeiksi, aukot täytetään naapuruston avulla ja tehdään koordinaattimuunnos suomalaiseen koordinaatistoon (TM35Fin, EPSG 3067). Tarkempia tietoja Sentinel-2 Global Mosaic-palvelusta löytyy osoitteesta https://s2gm.sentinel-hub.com/documentation. Sijaintihakemisto ..\feokk\distribution\Sentinel2_GlobalMosaic -- Sentinel-2 satellite image mosaics are produced from data provided by MultiSpectral Instruments (MSI) onboard Sentinel-2A and -2B satellites. These mosaics have been produced using Sentinel-2 Global Mosaic-service (https://s2gm.sentinel-hub.com/) of Copernicus program of European Union. The value of pixel is the estimate of ground reflectance, multiplied by coefficient 10000. Processing (lineage) Steps of mosaicking process (https://usermanual.readthedocs.io/en/latest/) at Sentinel-2 Global Mosaic service are: Selection of Sentinel-2 images of chosen area of interest and time period. Atmospheric correction of images using Sen2cor-algorithm. Selection of the least different pixel of time period from a set of good pixels. Production of output mosaic with chosen bands, pixel size and coordinate system. Tilewise mosaics are downloaded to local computer, where post-processing phase consists of merging of tiles to form bandwise mosaics, filling of gaps using neighboring values and coordinate transform to Finnish coordinate system TM35Fin (EPSG 3067).
