Detailed Description
Electronic navigational charts (ENC) are georeferenced vector datasets for the visualization and analysis of hydrographic and maritime information. ArcGIS Runtime supports ENC that conform to the International Hydrographic Organization (IHO) S-57 standard.
Functional characteristics
ENC layer supports identify and selection but does not support query or time. ENC layers cannot be displayed in a scene.
Performance characteristics
ENC layers differ from other layer types in that ENC content is cached in an internal collection of SENC files. When an ENC layer is displayed, only the content in the SENC files is referenced. SENC files are produced when an ENC cell is read for the first time and updated as update sets are applied. You can set the path to the SENC storage directory with the EncEnvironmentSettings::sencDataPath property. SENC files are in a binary format that is not intended to be shared between platforms or versions of ArcGIS Runtime.
// create ENC Cell using path EncCell* encCell = new EncCell(path, parent); // visualize ENC data in ENC layer. EncLayer* encLayer = new EncLayer(encCell, parent);

Member Function Documentation
EncLayer::EncLayer (Esri::ArcGISRuntime::EncCell *encCell , QObject *parent = nullptr)
Constructor that accepts the ENC cell (encCell), and an optional parent.
See also EncCell.
[override virtual] EncLayer::~EncLayer ()
Destructor.
Esri::ArcGISRuntime::EncCell *EncLayer::cell() const
Returns the ENC cell object associated with the ENC layer.
See also EncCell.
void EncLayer::clearSelection () const
Clears / Unselects a previously selected ENC feature (if any).
See also EncFeature.
[static] Esri::ArcGISRuntime::EncEnvironmentSettings *EncLayer::encEnvironmentSettings ()
Use this method to obtain a reference to the EncEnvironmentSettings object.
These settings apply to all ENC layers.
void EncLayer::selectFeature (Esri::ArcGISRuntime::EncFeature *encfeature) const
Selects an ENC feature.
Only a single ENC feature can be selected at a time. Selecting a feature using this method will unselect a previously selected feature.
- encfeature - The ENC feature to select.
Note: Some ENC features are rendered as multiple objects on the map - for example, a soundings feature might consist of many individual measurements, each of which will be highlighted when the feature is selected.
