Abstract

The grid was created from the Australian bathymetry and topography grid (2009, version 4). The data represents seabed rugosity of an area of seabed (a rectangle of 3 by 3 cells). The rugosity was measured as surface area (Jenness, 2004). Higher surface area corresponds with higher rugosity. Jenness, J. S. (2004). "Calculating landscape surface area from digital elevation models," Wildlife Society Bulletin 32, 829-839.

Lineage

The data is a derived product from the 250 bathymetry and topography grid (2009, v4). The processing steps include: 1. The bathymetry grid was first subset into 14 grids, each of which covers an UTM zone (from 46s to 59s). 2. They were then projected into UTM coordinate system. 3. The rugosity (surface area) was calculated from these UTM grids separately using an AML program written after Jenness (2004) with a rectangle window of 3 by 3 cells. 4. The 14 rugosity grids were projected back to WGS84 coordinate system. 5. The final grid (this data) was the result of mosaicing the 14 rugosity grids.
