If you have enabled Gridding Soundings in the Select Processing dialog box,
BathyPro makes available four more processing choices in the Processings on
Gridded Data panel:

• Fill Gaps filter

• Smooth filter

• Isocurves extraction

• Generate soundings chart

The fill gaps filter will reduce or remove any gaps in the data. Without modifying
any existing values, the smoothing filter will actually modify the data, producing a
smoother DTM. The filters can be applied during initial processing or applied
secondarily by importing DDS_VIF files as GRID file types.

Fill Gaps Filter

Clicking the Settings… button to this parameter leads to the Fill Filter
Settings dialog box (Figure 36). The Fill Gaps Filter allows you to fill
inherent spaces between sounding lines, both across track and along track.
It uses two different types of filtering, median and inverse, to fit the data.
