Adding bathymetry data to the BIS geodatabase (Bathymetry Solution)
The Add Bathymetry tool establishes the link between your raster datasets and the Bathymetry Information System (BIS) geodatabase. During the process of adding bathymetry, the BIS geodatabase stores and tracks each dataset’s location within the system tables while your bathymetry datasets remain at their physical locations (that is, local drive, network path, or DVD). By doing this, the system is referencing your actual bathymetry data holdings, not a copy, which keeps physical storage requirements down. You can create links to multiple datasets across a variety of storage locations in a single batch process.
Before you can add your source datasets with the Add Bathymetry tool, you will need to define the extended metadata fields for each file. Extended metadata fields can be updated on the datasets individually, across datasets in a particular folder location, or to all listed datasets. Optionally, you can apply a Collection feature to each dataset individually, across datasets in a particular folder location, or to all listed datasets; however, you will not be able to update the collection metadata.
You can configure the metadata field display for the Collection and Extended Metadata sections of the Add Bathymetry dialog box by adding new fields, adding field drop-down values, and hiding fields. The Internal Metadata fields are read directly from and are specific to the bathymetric attributed grid (BAG) dataset format. These fields have stricter limitations in the types of field modifications you can make.
Only users with Data Owner privileges on the BIS geodatabase can add bathymetric data.
All BIS users, both administrator and nonadministrator users, will need to have Read/Write access to the bathymetry dataset storage location. The bathymetry datasets need to be stored on a shared network path following the UNC conventions (for example, \\MachineName\Folder\Data).
If working in a multiuser environment, it is strongly recommended that only one user at a time add bathymetry data to the BIS geodatabase.
The following steps use the default metadata fields that come with the 深海探测学解决方案. If you have configured your own metadata fields, then your experience with these steps will be different.
- Start ArcMap.
- On the main menu, click Customize > Toolbars > Bathymetry.
Click the Add Bathymetry button on the Bathymetry toolbar.
The Add Bathymetry dialog box appears. Initially, the list of raster files to add is empty.
- Click Add Datasets to List.
The Select raster datasets to add dialog box appears.
- Browse to the location containing the raster files you want to add.注:
If a folder connection has not been created for the location of the raster files, you will need to create the folder connection.
- Select the datasets you want to add to the BIS geodatabase.
You can select multiple datasets.
- Click Add to add the datasets to the list.注:
If the datasets that are being added include rasters that are not in the BAG format, the following criteria need to be verified.
- If necessary, you can delete a dataset from the list:
To remove a single item
Click the icon next to the dataset.
To remove all datasets from the list
Click the icon next to the parent folder.
- If you want to copy the data to another location, perform the following steps.
There may be cases when you need to create a local copy of your raster data, rather than accessing it across a network connection. The Add Bathymetry dialog box allows you to set a location to which source data will be copied. This location overrides any copy locations set in the Manage BIS Settings dialog box, the Manage Collections dialog box, and the Create BIS Database dialog box.
- Check the Copy data to (Optional) check box.
- Click the ellipsis (...) to browse to a new location.
The Browse For Folder dialog box appears.
- Browse to and select the new location where the source data will be copied.
- Click OK.
- If you want the new datasets to be part of a collection, click the Collections drop-down arrow in the Collection Metadata section and choose the collection.注:
A dataset is not required to be part of a collection. When a collection is chosen, the dialog box will display the collection, extended, and internal metadata of the file. Clicking View Metadata XML will display internal metadata in an XML metadata viewer with expandable and collapsible levels. This is for display purposes only; metadata cannot be edited in the viewer.
- Click the Value cell next to IHO Survey Order in the Extended Metadata section, click the drop-down arrow that appears, and choose a value.
- Special Order
- Order 1a
- Order 1b
- Order 2
- Order 1 (deprecated)
- Order 3 (deprecated)
If you customized your Extended Metadata fields, the values for steps 11 through 14 may vary slightly from those listed below.
- Click the Value cell next to Sensor, click the drop-down arrow that appears, and choose a value.
- Sensor 1
- Sensor 2
- Sensor 3
- Click the Value cell next to Vessel, click the drop-down arrow that appears, and choose a value.
- Vessel 1
- Vessel 2
- Vessel 3
- Click the Value cell next to Data Type, click the drop-down arrow that appears, and choose a value.
- Single Beam
Internal metadata can be extended to include any custom information.
When the data has finished loading, a progress dialog box indicates that the datasets have been added successfully.
In addition to loading data into the BIS geodatabase, the Add Bathymetry tool will calculate statistics on the import rasters, create pyramids, create overviews, and calculate statistics on the Bathymetry Data Index.
