This is a new ArcPro Coral Mound Mapping (CoMMa) toolbox to semi-automatically map and characterise cold-water coral mounds.
At present, the toolbox includes three tools. The toolbox allows you to:
1) Pre-process multibeam data and calculate derivatives (i.e. bathymetric positioning index (BPI), directional and minimum median residuals) using the Auxilaries tool (see Figure 1 below)
2) Delineate potential mound features using the Delineation tool (see Figure 2 below)
3) Describe the geomorphological characteristics of cold-water coral mounds using the basic, texture and volume descriptors tools. These characteristics include the area, perimeter, width/length ratio, slope, vertical relief, BPI, depth, width, length, orientation, Polsby-Popper score for circularity, convex hull area, depth range, dissection index, texture, etc. – volume will be calculated using the Description tool see Figure 3 below).
The extracted morphometric data can be used to understand spatial patterns in shape, biodiversity and environmental conditions (e.g. current speeds and direction) of cold-water coral mounds across the ocean.
