Cloud-free Sentinel-2 mosaics of Norway, processed by the Norwegian Mapping Authority (Kartverket) and redistributed from Geonorge.
This collection provides cloud-free Sentinel-2 imagery mosaics covering Norway.
The initial release contains the 2015–2017 mosaic, compiled from imagery acquired across those years. It is a single multi-year mosaic. Additional annual mosaics will be added as they are verified and prepared.
The initial dataset contains RGB imagery in TIFF format, distributed in EPSG:25833 (ETRS89 / UTM zone 33N).
Cloud-free Sentinel-2 mosaics of Norway produced by the Norwegian Mapping Authority (Kartverket), sourced from Geonorge and redistributed by Christer Gundersen through Source Cooperative.
The 2015-2017/ directory contains one mosaic assembled from imagery acquired
in 2015, 2016 and 2017. It is a single multi-year mosaic, not three annual
mosaics. Additional annual mosaics may be added in separate directories.
The initial release comprises 85 raster tiles with their accompanying source files. The imagery is RGB TIFF in ETRS89 / UTM zone 33N (EPSG:25833). A sampled tile has approximately 10 m pixels; this has not been verified individually for every tile.
For the current release, the original ZIP archives were extracted and their
contents uploaded to the 2015-2017/ directory. The upload workflow did not
convert, reproject, resample or re-encode the imagery. Original accompanying
files, including external overviews and metadata, are retained.
These files have not been converted or validated as Cloud Optimized GeoTIFFs (COGs) by this project. Hosting TIFF files on cloud storage alone does not establish COG compliance. Any future conversion for efficient cloud access will be documented here together with the processing method and validation.
Kartverket's source metadata notes that the imagery has already been stretched to provide even transitions between tiles. Automatic RGB or gamma stretching in GIS software may therefore alter the intended appearance.

Redistribution: Christer Gundersen via Source Cooperative. The redistribution workflow changed the packaging from ZIP archives to individually accessible files; it did not change the imagery format. This redistribution does not imply endorsement by Kartverket or Copernicus.
License and attribution details for additional mosaics will be documented when those mosaics are published.
The downloaded ZIP archives were checked for expected file size and ZIP CRC, and local SHA-256 checksums were recorded. These checksums were not compared with independently supplied checksums from the producer. After upload, file sizes were checked using S3 sync. This is not an end-to-end checksum validation or a complete geospatial quality assessment.
