Specimen Image Databases for Taxonomic Research: Experiences on File and Metadata Handling
Arturo H. Ariño (Presenting), David Galicia. Department of Zoology and Ecology, University of Navarra, Pamplona, Spain.Digital image technology has provided a reliable, convenient way to store images of natural history collections’ specimens. Current web technology, and in particular shared taxonomic database schemas already developed or under development, can now ensure easy distribution and almost universal access to high-quality images formerly available only through hard copies.
In many respects, the caveats and shortcomings of these digital images are very similar to those on the traditional chemical photography. However, metadata from digital images are much easier to document and maintain, i.e. as EXIF data. Additional metadata and imaging procedures can be used to store information that dramatically increases the validity of these images for taxonomic studies, i.e. by facilitating biometrics or image analysis.
We will discuss some experiences on this taxonomically-oriented use of scientific imaging, including considerations on imaging, precision, morphometrics, colour reproducibility, metadata, formats, databasing, and storage efficiency.
