Methodology

Study extent

Digitization of vascular plant and bryophyte specimens from the Marie-Victorin Herbarium (MT), with a focus on Asteraceae, Cyperaceae and Poaceae.

Sampling description

All data are manually digitized as text from specimen labels. No images were taken

Quality control

Legacy data have been formatted to fit the new database structure and have been cleaned to the best of our abilities, but they might still contain inconsistencies. They are further corrected on a ad hoc basis. New records are entered using controlled vocabularies where relevant and should contain fewer errors.

Method Steps

  1. Examine specimen and any attached/included labels. Verify and update determination if qualified.
  2. Search specimen record in collection database and update where necessary, or create new record and populate fields with the information on the specimen label. Use controlled vocabularies where relevant. Determinations are recorded in a related table (included in this dataset as http://rs.gbif.org/extension/dwc/identification.xml), as are related projects and specimen exchange history.
  3. Attach the newly generated specimen number to the physical specimen.
