All maps have been given a unique DOI, which is also included on the scans. Furthermore, 'related publications' such as map descriptions and separate legends are also included for download via a separate (doi-)link in the metadata description section.
The maps – 145 in total – have all been scanned at 400 dpi (tiff) and converted to pdf. Both file types are available for download from GEUS’ Dataverse-portal.
