The video analysis data was checked in Microsoft Access for blank fields and
erroneous GPS positioning and habitat classifications. The data were then converted
into a GIS shapefile (point data) and displayed in Arc GIS software for further error

of the major habitat categories (i.e. macroalgae, hard coral, filter feeders, soft coral
and seagrass) at each survey site. The point data were reviewed for any habitat
