Southern Hemisphere Blue Whale Catalogue photo quality coding guide
Olson PA, Galletti Vernazzani B, Torres Florez, JP
The Southern Hemisphere Blue Whale Catalogue (SHBWC), sponsored by the IWC, is an internationally collaborative repository of photo-identification catalogues from throughout the Southern Hemisphere. The objective of the SHBWC is to facilitate cross-regional comparisons of individual blue whale photo-identifications contributing data for population assessments conducted by the IWC. Prior to analysis, the identification photographs often need to be coded for quality. This guide provides a standard for the quality coding process.
