Application of Landscape Mosaic Technology to Complement Coral Reef Resource Mapping and Monitoring

Abstract

The primary objective of SI 1333 was to develop innovative technology to increase the speed and repeatability with which reef plots can be mapped and inventoried. Specifically, we used underwater images to create landscape (2D) mosaics of reef plots in a highly automated way. The innovative aspect of the mosaicing technology is that the images provide both landscapelevel (meter-scale) maps and high-resolution (sub-millimeter) images of individual coral colonies. Users can collect imagery for areas of several hundred square meters in under an hour of in-water dive time to create mosaics that provide information on coral colony health and small-scale competitive interactions. The mosaic products are useful for extracting ecological indicators of reef health and for damage assessment; they also have excellent archive potential and are superior tools for tracking changes over time.
