Add additional columns

For each additional column attribute included in the source data, an additional item must be added to the File items list. To add additional items:

A new item, labelled NewColumn, is added to the tree structure and displayed in the Column Name field in the Properties list. The name can be changed to something more specific either:

• by selecting an option from the Column Name drop-down list, or,

• by manually entering a name in the field.

The drop-down list contains default column names for each of the available file types. For a navigation file, “DatagramTime” is provided. For an elevation file, you can choose between “DEPTH_TPU” and “POS_TPU”, both of which are meant for uncertainty data.

If a name is selected from the drop-down list, the remainder of the Properties fields will either be populated with default values or be disabled, as they are defined automatically by the selection.
