S57 CellInfo

This sample demonstrates adding and removing S-57 cells from an HydrographicS57Layer in the Map and accessing the Dataset Identification (DSID) metadata of those S-57 cells. The DSID metadata Provides information regarding the dataset's source and the product specification it is part of. The sample uses a ListBox control whose ItemSource property is bound to the Cells property of the HydrographicS57Layer instance. Other controls are bound to specific properties of the selected S57Cell instance to display the metadata values.
