Abstract

Abstract

This paper reviews current fusion techniques used for bathymetry data, introduces the "Splines-in-Tension" interpolation and "remove-restore" techniques for bathymetry fusion. Based on these techniques, high-resolution digital bathymetric model is built using multi-beam, single-beam and historical charts data sets. In addition, facing the lack of error estimates for the interpolated grid points, the paper uses split-sample method to assess the uncertainty of the result for reliability. It shows a satisfied result with error percent about 0.5% both in sparse and dense areas, preserving the detail information of high-resolution data, possessing the vivid characteristics of the sea bottom. The whole techniques can be applied in multi-sources data fusion and combination.
