Description:

"We have developed a method of assessing errors in altimetric bathymetry models. This method was used in the paper 'Evolution of errors in the altimetric bathymetry model used by Google Earth and GEBCO' by Marks et al. (2010) to evaluate errors in the Smith and Sandwell (1997) bathymetric model and its updates. The technique involves comparing model depths to multibeam 'ground truth' depths, with 'errors' being the differences. Other gridded bathymetry data sets and interpolation algorithms can likewise be tested if selected control data are withheld for subsequent comparison to resulting grids. This technical report serves to document our error assessment method in detail"--Abstract.
