Digital Elevation Model of Norfolk Island and Sydney Bay, Australia
For the purpose of studying the impact of the 10 February 2021 South Matthew Island tsunami in the southwest Pacific Ocean, a set of three digital elevation models (DEM) of Norfolk Island, Australia, including a high-resolution focus on Sydney Bay (on the south coast of the island) has been built using three different types of data.
They include:
- The global dataset 15 arcsec resolution GEBCO (2020);
- The global dataset 1 arcsec resolution SRTM (2013);
- Norfolk Island LiDAR 0.57m DEM (Gallant and Petheram, 2020);
- Digitized and georeferenced nautical chart of Norfolk Island (Australian Hydrographic Office, 2019) and related charts (Australian Hydrographic Office, 2009a, b, c, d).
The data showing the highest resolution has been kept in priority.
The compilation of data has been interpolated to a regular spatial resolution of 0.005° (~500 m) for the coarser grid, 0.0005° (~50 m) for the medium grid, and to 0.0001° (~10 m) for the grid over Sydney Bay. The data interpolation processes have done using the kriging method. For more information about this method, see for example Oliver and Webster (1990).
