Abstract

The grid was created from the Australian bathymetry and topography grid (2009, version 4). The data represents the degree of aspect of a slope surface (a rectangle of 3 by 3 cells).

Lineage

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