“…Airborne blue-green lidar mapping of shallow benthic environments has several advantages over boat-based acoustic surveys (Costa, Battista, and Pittman, 2009). For example, 1) navigational hazards associated with vessel operations nearshore are not an issue, 2) the lidar swath width is nearly independent of water depth, 3) hybrid blue-green lidars with high pulse rates can collect almost seamless subaerial-submarine topobathymetric surveys, and 4) airborne lidar can also collect reflected intensity images useful in benthic class discrimination (Costa, Battista, and Pittman, 2009).…”

“…Uncertainties in interpreting single-beam acoustic backscatter observations have limited the use of that method for producing thematic coral reef habitat maps (Costa, Battista, and Pittman, 2009). Foster et al contribute to the resolution of this ambiguity by using a comprehensive high resolution lidar groundtruth data set to derive proxies for topographic complexity, reefvolume, and benthic habitat class that are then applied to evaluate the utility of acoustic energy parameters in reef benthic characterization.…”

“…Especially the pulse repetition rate and, thus, the point density have been signifi cantly increased with the state-of-the-art sensors. Good results under optimal conditions were reported (Costa et al, 2009;Steinbacher et al, 2012). However, there are many limiting factors like water turbidity, waves, and refl ectance conditions of the sea bed.…”

“…Thus, it is an alternative technique compared to conventional (multibeam) echo sounder data of ships, which is even more time consuming and costly, e.g. Guenther et al, 2000, Costa et al, 2009. The LiDAR system uses two lasers, a green laser which can penetrate the water column and an infrared laser, which is reflected at the water surface.…”
