# Copernicus Global Land Cover Layers--Collection 2
## 4 Data Access Channels  
To improve the accessibility, the CGLS-LC100 Collection 2 product as well as the product documentation is distributed via several access channels:  
* The LC layers are available for viewing through the Global Land Cover viewer, available at [[https://land.copernicus.eu/global/lcviewer](https://land.copernicus.eu/global/lcviewer)]([https://land.copernicus.eu/global/lcviewer](https://land.copernicus.eu/global/lcviewer)). It displays the various LC layers (discrete map, cover fractions, false-color combinations of cover fractions) on a map, allows us to download the data in 20x20 degree tiles in the EPSG:4326 projection and reports on LC statistics per administrative area.
* All products are uploaded on the Zenodo platform for long-term archiving and assigned a concept DOI as well as a version DOI. The concept DOI will resolve all the time into the newest collection of the dataset. Moreover, the single layers of the CGLS-LC100 product can be downloaded as single global files in the ESPG:4326 projection (Table 5).
* so now the access through the Google Earth Engine (GEE) offers on-demand analyses, visualization and data download in Pseudo-Mercator projection for customized boundary boxes. Search for the term \"Copernicus Global Land Cover Layers: CGLS-LC100 Collection 2\" in the GEE Data Catalog.
* The product is also available through the Geo-Wiki engagement platform available at [[https://www.geo-wiki.org/](https://www.geo-wiki.org/)]([https://www.geo-wiki.org/](https://www.geo-wiki.org/)). The user can compare the CGLS-LC100 product with other global and continental LC products as well as provide feedback or help to collect additional training points for the next collection of the product.
* More information and documentation about the CGLS-LC100 product is available from the Copernicus Global Land Service web site at [[https://land.copernicus.eu/global/products/lc](https://land.copernicus.eu/global/products/lc)]([https://land.copernicus.eu/global/products/lc](https://land.copernicus.eu/global/products/lc)) as well as accessible through the \"Copernicus Global Land Service: product documentation\" community on the Zenodo platform at [[https://zenodo.org/communities/copernicus-land-product-documents/](https://zenodo.org/communities/copernicus-land-product-documents/)]([https://zenodo.org/communities/copernicus-land-product-documents/](https://zenodo.org/communities/copernicus-land-product-documents/))
