Abstract:
The software tool MergeBathy (2015) combines one or more bathymetric data files onto a single input grid. Regression and Kriging of this merged input data then produces a custom digital elevation model. MergeBathy is cross-platform, multi-threaded, and provides multiple interpolation/data fitting methods and smoothing scales across multiple data sets. In addition, MergeBathy provides uncertainty estimation as a fundamental task.

In this paper, we describe the functionality of MergeBathy and present its software architecture. We include the major code sections, which perform up- and down-sampling, offset computations, regression, Kriging, uncertainty estimation, and file writing. We also include a discussion of the fundamental data structures and algorithms available.
