Seabed Survey: Boulder - Heather Island

In temperate environments, boulders and rocks are important hard substrates for a number of sessile organisms, especially in sedimentary areas. In addition to this, they provide niches and habitats for commercially important species such as lobster and crab. Photogrammetric modelling can be used to calculate the size and depth of such niches. This data, along with a larger scale distribution of hard substrate, can be factored into the habitat availability of an area. 

Boulders and rocks can also complicate the deployment of undersea structures and pipelines, and quantifying their abundance is a factor in where to progress such works. 

Interactive 3D Model

Model navigation and controls

Move camera: 1 finger drag or Left Mouse Button
Pan: 2-finger drag or Right Mouse Button or SHIFT+ Left Mouse Button
Zoom on object: Double-tap or Double-click on object
Zoom out: Double-tap or Double-click on background
Zoom: Pinch in/out or Mousewheel or CTRL + Left Mouse Button
Double-clicking the background also re-centers the model and sets the camera pivot point to the middle of its bounding box. Double-clicking anywhere on the model sets the camera pivot point to that spot.
