An index of the maps in the De Haan collection of maps, including descriptions, scale, units of measurement, topic, location in the archive, the material the map is made of and more. These maps used to be part of the VOC archives, but were turned into a seperate collection by Van der Chijs and De Haan.
Unfortunately, it is unclear who managed the data in the digitization process.
CC BY-NC-SA and scientific datasets
CC BY-NC-SA requires attribution, restricts use to non-commercial purposes, and requires adaptations to be shared under the same licence. For scientific datasets, the NC (NonCommercial) clause can be problematic because it may prevent reuse by commercial researchers, industry, or organisations whose activities include commercial purposes. The SA (ShareAlike) clause can also complicate combining the dataset with other data or incorporating it into projects distributed under different licences. These restrictions may reduce interoperability, reproducibility, and broad scientific reuse. For datasets intended as open research infrastructure, more permissive licences such as CC BY or dedicated data licences may therefore be preferable.
