Data can be stored in a Nautical Information System (NIS) database for editing and maintenance. When implementing the NIS, there are some decisions that an organization needs to make. First, the organization needs to choose a database format to use for the NIS, such as file geodatabase, Oracle, or SQL Server. Once it is configured, the database is then ready to load the NIS schema in one of the following environments:
One of the benefits the NIS database offers is that multiple-scale data can be stored in one central location for easy editing access. Each feature class in the NIS schema contains the field PLTS_COMP_SCALE, which identifies the compilation scale of the feature data.
Loading data
When loading data using the S-57 To Geodatabase tool, the PLTS_COMP_SCALE value populates according to the CSCL or M_CSCL value in the S-57 cell. The S-57 importer takes care of populating this value for you; however, if you choose to load data via an alternative method, this attribute field needs to populate in an edit session after loading.
- Start ArcCatalog.
- In the Catalog window, right-click the Nautical feature dataset and click Import > S-57 to Geodatabase.
The S-57 to Geodatabase dialog box appears.
S-57 to Geodatabase dialog box for importing into an NIS database - Click the browse button (...) next to the Input S-57 Cell text box.
- Navigate to and choose the S-57 cell you want to import.
- Click Open.
- Check the Override CSCL and M_CSCL values check box to enable the grid view for editing.
If you are importing into NIS, the Override CSCL and M_CSCL values grid is populated with rows that show the imported cell's DSPM:CSCL and M_CSCL:CSCALE values.
- Click the cell in the Override column and type the new value for the DSPM:CSCL and/or M_CSCL:CSCALE value.
The updated values are populated into the COMP_SCALE property during import.
- Click OK.
A status dialog box appears.
When the process is complete, the S-57 to Geodatabase dialog box appears and asks you if you want to view the log file.
- Click Yes to open and review the log file.
The log file shows the following information:
- Metadata information that was imported, such as dataset ID (DSID), dataset structure information (DSSI), and dataset parameter (DSPM)
- The new value, if you have imported into an NIS database and replaced the imported cell's CSCL value with one of your own
- The number of features and primitives that were imported
- The amount of time it took to import
- Any errors that occurred (listed at the top of the log file)
- The import version name that was created and populated, if you imported into an enterprise geodatabase
- The amount of time it took to read the file for the override option (NIS only)
- Close the log file once you are finished reviewing it.
- If you are working in a versioned environment, you will need to reconcile and post your data from the import version to the Default version.
Populating the compilation scale when editing
When working in the NIS database, you are required to establish the scale at which you are compiling data so that newly created features can be managed correctly. To ensure features filter correctly to the ENC during export, the value stored in the compilation scale property must populate the PLTS_COMP_SCALE attribute on each feature created during an edit session. This attribute can also be leveraged to control the display of data while editing in the NIS.
You can set the compilation scale property with the Compilation Scale tool. This tool provides an easy way to review and dynamically alter the compilation scale value of newly created data without having to stop the edit session.
- Start ArcMap.
- On the main menu, click Customize > Toolbars > Nautical.
-
Type a value directly in the Compilation Scale text box and press Enter.
You cannot use 0 (zero), negative values, or nonnumeric characters.
