Digital Elevation Models (raster format) from bathymetric surveys from 1862 to 2021 (Babytonga bay, southern Brazil)


Steps to reproduce

The DEM were constructed through EBK interpolation method. The autocorrelation parameters in EBK method were automatically calculated using measured and simulated data, including the radius of searching (Krivoruchko, 2012). The number of semivariograms simulated for each subset, and the number of points in each subset were kept at 100. The neighborhood type parameter chosen was the Standard Circular. The remain parameters Overlap factor and Angle were kept in their default value of one and zero. The decision not to impose a specific direction for interpolation when using the EBK method relies on the method’s capability to develop a semivariogram for each spatial domain. Hence, it was chosen not to enforce autocorrelation in a particular direction, allowing correlation models (semivariograms) to be generated according to the spatial variations within each subset. Different semivariogram types (Linear, Power, and Thin Plate Spline) were examined, and the one associated with the lowest Root-Mean-Square Error and Root-Mean-Square Standardized Error closest to 1 was selected. The semivariogram type, the number of neighbors, and the sector type applied for each dataset are detailed in Table "setting parameters".
