Draw a loop around an area with a finger or the mouse, then say how high it really is. Drawing over an area again replaces the loop there. Loops are kept in this browser; download them for the next rebuild of the model.
Seabed: NSW Marine LiDAR Topo-Bathy 2018, 5 m grid, © Department of Planning, Industry and Environment, CC BY 4.0. Map: Marco Bordieri, surveyed 2020–21, CC BY-NC-ND. The map has been fitted to the LiDAR by up to 12 m, mostly on the deep west side. The shape of the seabed comes from the map: sand is one smooth floor, rock rises from it on a slope, and the seabed is vertical only where the map draws a wall, at depths from the LiDAR. Rocks too small for the LiDAR stand 0.6–2 m proud by size. Zero tide is 0.925 m below mean sea level in Sydney. Depths in the fly-through are below mean sea level, with no tide added.
A simulation for planning and fun only. Depths come from a model of the seabed and may be wrong; the no-decompression time is computed from Bühlmann ZHL-16C with no conservatism and is not dive planning. Dive within your training and your own computer. VIZ takes no responsibility for any use of it.
