Digitization of types

Digitization of vascular plant type collections at the Department of Botany (S)

A digital technician uploading metadata.

Uploading metadata

Digitization procedure means capturing images and data (metadata) and storing them in the digital form. Team members at our department revise and enhance specimen data entered into our on-line database Herbarium Catalogue. Type records are reviewed and their status are verified through examination of their original publications. The aim is to provide as much information as possible. The most important information is the collection label.


In the complete absence of information or data about key fields (collector, number, country etc), the digital technicians enters “not on sheet" in the specific field. Older specimens, i.e. those from the first half of 19th century or earlier entered information is often based on collectors´ handwritings and/or collectors history. The work involves research and specific knowledge.
The quality control process ensures that new data has been entered and edited correctly. After a specimen has been checked and annotated, it is imaged using one HerbScan.

Details of scanned plants

Specimens are scanned with a resolution of 600 dpi, corresponding to about seven times magnification. This is standard for the GPI project. Images are saved as uncompressed TIFF-files, but also as jpeg-files for Herbarium Catalogue.

The images are stored in the museum servers, sent to JSTOR on a portable disk drive and uploaded to our botanical database Herbarium Catalogue. Some images or interesting facts are also shared in Facebook.
