Create a new feature layer. You can use a feature layer to create new features or edit existing features.
You can copy existing features to a feature layer using the Import Selected Objects command.
You can save the contents of a feature layer using the Save command. By default the contents of the layer will be saved to a HOB file. If the data meets any of the following criteria, it will be saved as an H2O file, which is a CARIS feature-based format:
• the data contains feature acronyms with more than 6 characters
• the data contains attributes with multiplicity
• the data uses an S-100 catalogue
If you close a feature layer or exit from CARIS, you will be asked if you want to save the feature layer.
Interface
The Create Feature Layer command uses the following dialog box.
Option | Description |
Spatial extents | Define the extents of the feature layer. This section of the dialog box is only displayed if there is no data open in the application at the time the command is launched. If data is open, the extents of the view are automatically used as the extents for the feature layer. 1. Choose a coordinate type: Ground or Geographic. The labels change to reflect the type. 2. Type lower-left and upper-right values in the coordinate fields. |
