The user can select individual lines by clicking on the check box to the right of the line name,
or the user may choose 'Select All' or 'Deselect All'. If a line is deselected, it will not be
included in the DTM that is being created. Using the 'Add Lines' tool, it is possible to append
the DTM with the lines not included at a later time.
When finished selecting the lines to include in the processing, click the 'Next' button to
advance to the next processing step.
5.2.5 Gridding of Soundings
This page of the processing wizard as shown below gives the user the option to set output
resolution, encoding options, fill and smoothing options, and the option to constrain the DTM
to the map extent.
Resolution:
Enter the resolution of the DTM in meters per grid cell.
Note that the resolution chosen should be something appropriate with regard to the water
depth, number of beams, etc. This is also the "bin" size into which the raw bathy soundings
will be gridded. The resolution sets the grid cell size and therefore the smaller the number,
the larger the DTM file size of the final DTM file and the longer will be the processing time.
