During making a grid for water bodies, viewing the bathymetry underneath the gird is meaningful as it gives an idea about the high resolution of cells in the deep and main channel regions and the low resolution of cells in shallow regions. The Data menu supports do this. It includes Grid Bathymetry Interpolation and Download Online Bathymetry as shown in Figure 1. The function of each option is described in the table below.
