The Influence of Interpolation Methods and point density on the Accuracy of a Bathymetric Model

The Effect of the Density of Measurement Points Collected From a Multibeam Echosounder on the Selection of IDW Interpolation Points in the Process of Creating Seabed Models

“…This set is then divided into two subsets: a larger one, used to create DTM models (using various interpolation methods), and a second, smaller one, to verify the accuracy of the generated DTMs (determination of depth errors). Such an approach to accuracy verification can be found, for example, in the work [23,24]. The advantage of this approach is the use of actual data from measurements.…”
