Filter by metadata

You can filter bathymetric data in ArcGIS Pro using the Explore Bathymetry tool. Bathymetric data must be stored in a Bathymetric Information System (BIS) to be analyzed using the filters in the Explore Bathymetry pane.

BIS data can be filtered by the metadata fields listed in the Fields To Display column of the BisDetails table. You can filter by text and numeric values, including item name, percent coverage, cell size, and elevation range. By filtering based on metadata, you can create a data subset that fits your analysis needs. You can also filter by extent to apply the Explore Bathymetry filters to only the data on the map.

Complete the following steps to open the Explore Bathymetry pane and filter by metadata:

1. Start ArcGIS Pro.
2. Open a project containing a BIS and add the BisCatalog or the BisBDI to the map.

   注意:

   You can use the Create BIS tool in the Bathymetry toolbox to create a BIS geodatabase.

   The Bathymetry tab appears on the ribbon.

   注意:

   If you previously added BIS layers to the map and the tab is not visible, click the area of interest in the map to activate the Bathymetry tab.

3. Click the Bathymetry tab.
4. On the Bathymetry tab, in the Explore group, click Explore Bathymetry.

   The Explore Bathymetry pane appears.

When the Explore Bathymetry tool is used for the first time in a project, it prompts you to add an Explore Bathymetry group layer to the map.
5. Click Add Group Layer to add the Explore Bathymetry group layer to the map if necessary.

   When the group layer is added to the map, the following occurs:

   • The Explore Bathymetry group layer is added to the map. It consists of BisCatalog and BisBDI layers named BisCatalog_EB and BisBDI_EB on which the Explore Bathymetry filters act.
   • The default metadata fields and any custom fields appear in the Explore Bathymetry pane.

   You can now filter bathymetric data by providing values for the filter parameters in the pane, along with any custom metadata attribute fields you added to the Fields To Display cell in the BisDetails table.

6. Set the filter parameter values.

   Filters are derived from the BisCatalog Footprints table fields and appear as filters in the Explore Bathymetry pane when the field names are included in the Fields To Display cell of the BisDetails table. All filters are optional. Refer to the table below for guidance on how to use each default filter:

   Filter field	Description	Data type
   Item Name	The name of the dataset. Type a name or partial name as shown in the BISCatalog Footprints table into the Item Name text box. For example, type REG2 in the Item Name text box to include only datasets with REG2 in their names.	Text string
   Data Type	The type of raster or vector data you want to include. You can only filter by one type of data at a time when using this filter. To include multiple data types in the filter, leave this field blank. To filter by data type, choose one of the following from the drop-down menu: ASCII Grid BAG CRF Esri Grid Floating Point Grid GDB Raster GeoTiff (Elevation) GeoTiff (RGB) HDF5 Line Mosaic Dataset MRF Multipoint netCDF Other Point Point Cloud (LAS) Point Cloud (LASD) Polygon Shapefile	File
   Percent Coverage	The percentage of pixels containing real values (data that is not null) in the dataset. Type lower and upper percentage values or adjust the slider bar to create a range limit.	Numeric string
   BIS Cell Size	The cell size of a raster or proxy raster dataset in the horizontal unit of the BIS geodatabase. Type lower and upper cell size values or adjust the slider bar to create a range limit.	Numeric string
   Vertical Units	The unit of measurement of the elevation values in the dataset. Choose one of the following from the drop-down menu: Fathoms Feet Meters	Units
   Directionality	The measurement direction of the elevation or depth data. Choose one the following from the drop-down menu: Positive Down Positive Up	String
   Min Elevation	The minimum elevation range for data you want to include. Type lower and upper elevation values or adjust the slider bar to create a range limit. For example, create a minimum elevation range from 0 to 3 to include datasets that have a minimum elevation value between 0 and 3 (feet). The units depend on the vertical units value that is provided in the Vertical Units parameter.	Numeric string
   Max Elevation	The maximum elevation range for data you want to include. Type lower and upper elevation values or adjust the slider bar to create a range limit.	Numeric string

   注意:

   If you have an existing filter file that you want to use, you can load a saved filter file. The filter file must be based on the same BIS or another BIS with the same schema.

7. Optionally, turn on Filter by Extent to apply filters to only the active map view.

   Keep the following in mind:

   • Filter by Extent is off by default. Leave it off to apply filters to all data in the selected BIS.
   • Filter by Extent is not honored in saved filter files.

8. When you have provided values for each filter that you want to use, click Apply to filter the data in the Explore Bathymetry group layer.

   The data on the map and in the BISCatalog_EB Footprints table is filtered according to the parameter values set in the Explore Bathymetry pane.

9. Optionally, click Reset to remove all filters.
10. Optionally, use the Refresh button in the options menu to refresh the Explore Bathymetry pane if you added or removed BIS layers from the map, updated the BIS schema, or edited cells in the BisCatalog table.

You can now review the filtered data on the map and in the BisCatalog_EB Footprints table. You can also save the filter set and apply it to other bathymetric data in ArcGIS Pro or load the saved filter in the Bathymetry web app.

注意:

Filtered results from Explore Bathymetry sessions are not saved as part of an ArcGIS Pro project. To save the filters you created, you must save a filter file.
