S-57 ENC data sometimes contains sounding features that have been grouped into a single entity. When these soundings are imported into a feature layer in BASE Editor, they cannot be used for certain functions, such as creating a TIN, in their current form. To make the soundings functional, they must be returned to individual sounding features. This is accomplished using the Ungroup Soundings command. When soundings are ungrouped, each sounding has the same attributes as before it was grouped.
Procedure: Ungroup All Sounding Groups
1. Select the child layer of the dataset containing the sounding groups.
2. Select the Ungroup All Soundings command.
Menu | Edit > Ungroup Soundings > All |
The soundings in all groups can now be selected and computed as individual features. A message is displayed in the Output window stating that all soundings were ungrouped.
Procedure: Ungroup the Selected Sounding Group
1. Select the child layer of the dataset containing the sounding groups.
2. Select a sounding group in the display.
3. Select the Ungroup Soundings command.
The soundings in the selected group can now be selected and computed as individual features. A message is displayed in the Output window stating that the soundings were ungrouped.
