Image-based Data
Nature: Image-based data can be classified by the method used to produce them and include
- Scanning Electron Microscopy (SEM) images
- Light microscopy images
- Photographic data: field photos, sample photos, macro photos, etc.
- Herbarium image data: Photograph of specimens, labels, spirit collections, fruits, etc. taken during herbarium visits or provided by herbaria that don’t have associated online records or online scans.
Storage / folder organization
SEM images and LM images
- Store all image data under a centralized location, organized by project and type of imaging
- Main folders for each project, with subfolders for each type of image data.
- Subfolders within each type to further organize by date, specimen, or other relevant categories.
Naming conventions:
- Use descriptive names reflecting the content, include relevant details in the file name
Herbarium images
Folder structure: Store in a dedicated folder for "Herbarium image data" within a project folder. If necessary, create subfolders for different herbaria or taxa.
Naming convention: Include the herbarium acronym, the taxon and date of the photograph. Ensure that the collection metadata referring to the specimen are linked for pictures showing only a part of the specimen.
Publication: Respect any copyright or usage restrictions imposed by the herbarium from which the image was taken. Ensure proper citation and acknowledgment of the source herbaria.
Metadata documentation:
Each set of images should include metadata detailing
- Imaging conditions (e.g., lighting, settings)
- magnification level
- Sample preparation method
- Image creator (photographer or technician)
- Usage rights and CC-license
Store metadata in a README file or as part of the image file properties.
Retention:
Retain key images used in publications and other important images. Periodically review and delete redundant or low-quality images that are not necessary for future reference or publications.
Publication:
Ensure that image creator and copyright are indicated.
