Previewing filtered bathymetry

Previewing datasets

The Explore Bathymetry window not only allows you to filter datasets by metadata values but also provides you the opportunity to preview your filtered datasets as a single, seamless surface. Once you have added your previewed surface to the Table Of Contents window, you can continue to update your filtered list of datasets and watch your Explore Bathymetry Preview mosaic layer update dynamically as well. As your filtered dataset list grows or shrinks to include or exclude datasets, or even becomes entirely reset to reflect all datasets in your BIS, the Explore Bathymetry Preview layer will respond by showing only those datasets left in the filtered list.

This functionality pertains to filtering by properties, extended metadata, collection metadata, or internal metadata, as well as to filtering spatially to just those datasets that intersect the current data frame extent.

Tip:

You can optionally click the Clear Filters button at the top of the Explore Bathymetry window to return all filter controls to the default values.

You can visualize the datasets on the screen using the following steps:

1. Click the Explore Bathymetry button on the Bathymetry toolbar to open the Exlpore Bathymetry window.
2. Click the Preview button .
3. The Explore Bathymetry Preview and Bathymetry Data Index mosaic layers are added to the Table Of Contents window.

   Note:

   By default, only the Footprint mosaic sublayer of the Explore Bathymetry Preview layer is checked.

4. Optionally load any filter file or manually apply any filter of your choice.
As the filtered list updates, the Explore Bathymetry Preview mosaic layer will update showing only the footprints of those datasets still included in the filtered list.
5. Optionally check the Image sublayer of the Explore Bathymetry Preview layer.

   The datasets are now visualized on the screen.

   Note:

   For the most responsive map redrawing, leave only the Footprint mosaic sublayer turned on. The Explore Bathymetry Preview mosaic layer does not take advantage of overviews. Thus, redrawing the Image sublayer may take a while to render.

Selecting datasets

Once the Explore Bathymetry Preview mosaic layer has been added to the Table Of Contents window, the ability to select dataset footprints from the Footprint sublayer becomes enabled. As dataset footprints are selected on the map or in the table view, the equivalent datasets in the Explore Bathymetry Filtered Datasets list will be selected as well. This also works vice versa: as datasets from the Filtered Datasets list are selected, their equivalent footprints from the Explore Bathymetry Preview mosaic layer will be selected. This two-way selection allows more robust exploration of your bathymetry data since it opens additional avenues for highlighting links between the metadata of your datasets and the geospatial context that goes along with them.

Tip:

You can also use Select By Attributes and Select By Location to further extend the capabilities of the selection synchronization between the Explore Bathymetry Filtered Datasets list and the Explore Bathymetry Preview sublayer.

1. Add Explore Bathymetry Preview to the Table Of Contents window.
2. Select a dataset from the Filtered Datasets list.

   The footprint of the dataset is selected on the map.

   Note:

   If the dataset is not currently in view, right-click the dataset from the Filtered Datasets list and click Zoom To or Pan To from the context menu. Alternatively, click the Preview button on the Explore Bathymetry window to bring the entire extent of the Filtered Datasets list into the data frame.

3. Click the Select Features button to make a new selection of the datasets on the map.

   The datasets you have selected on the map are selected in the Filtered Datasets list.

4. Right-click the Footprint sublayer in the Table Of Contents window and click Open Attribute Table from the context menu.

   Only the records that are selected in the Filtered Datasets list are selected in the Attribute Table window that opens.

5. Select a different dataset from the Attribute Table window.

   The selection synchronizes with the selection in the Filtered Datasets list.

   Tip:

   For more advanced workflows, try exporting the metadata from your BIS using the Export BIS Metadata tool and joining the output table to the Explore Bathymetry Preview Footprint sublayer using the ID and BisDatasetId fields, respectively. Once joined, you can use Select By Attributes to execute more complex SQL queries that contain OR, IN, LIKE, and NOT statements. The results of these queries will yield datasets selected in your Explore Bathymetry Filtered Datasets list. You can even use Select By Location to select datasets in the Filtered Datasets list with points, lines, and polygons. This allows you to highlight datasets with a finer degree of spatial granularity than what is possible with the Explore Bathymetry Filter To Current Extent button .

6. To toggle the Filtered Datasets list between all the datasets returned by the applied filters, click the Show All Datasets button . Alternatively click the Show Selected Datasets button to view just those datasets whose footprints are currently selected from the Explore Bathymetry Preview layer.
