The map above shows optical validation survey sites at Ta’u in 2004 and 2006. Each point represents an analyzed video frame or photo.
The optical data are classified by substrate type, type of live growth on bottom, geomorphic zone, and the size and abundance of holes in the substrate. Maps showing the results of video/photo classification will be posted as soon as they are completed. Shapefiles and attribute tables of the classified tracks will also be available for download. The shapefiles will enable users to map the occurrence of any combination of characteristics that are included in the classification scheme.
