Abstract
Imagery collected by still and video cameras is an increasingly important tool for minimal impact, repeatable observations in the marine environment. Data collection from imagery is based on identification, annotation and enumeration of biological subjects and environmental features within an image. For such annotation data to be long-lived and useful beyond their project specific initial purpose, they need to be widely understood. A standardized annotation vocabulary is needed in order to generate regional, national or even global data sets from multiple sources to address broad-scale conservation and ecosystem-based management questions, and also for the development of computer algorithms to automate annotation. This need was addressed, within the Australian context, through the Collaborative and Automated Tools for Analysis of Marine Imagery (CATAMI) project (www.catami.org). The CATAMI classification scheme (CCS) is designed to annotate benthic substrates and biota in marine imagery. It is the first nationally standardised classification based on combinations of coarse-level taxonomy and morphology. The CCS is a flexible, hierarchical classification that bridges the gap between habitat or biotope classifications and taxonomic classifications, allowing for limitations in identifying biological taxa specific to imagery. The CCS is well described, documented, and maintained through web-based data-bases (www.catami.org and http://www.cmar.csiro.au/caab/), and it can be applied across benthic image collection methods, annotation platforms and scoring methods. The CCS was released in 2013 and has already been taken up by on-going Australian marine monitoring programs and by industry environmental consultants. Its incorporation into newly developed on-line image annotation tools further strengthens its continued use and development.
