Public propertyDataQuality
Gets or sets a value indicating whether to display data quality (M_QUAL) for S-57 features.
Public propertyDeepContour
Gets or sets the deep water contour depth in meters.
Public propertyDisplayCategories
Gets the ENC display categories object, which contains categories base, standard, and other.
Public propertyDisplayDepthUnits
Gets or sets the depth units (meters/feet/fathoms) for display.
Public propertyDisplayNOBJNM
Gets or sets a value indicating whether to display the national name attribute on S-57 features.
Public propertyHonorSCAMIN
Gets or sets a value indicating whether the 'SCAMIN' (scale min) S-57 feature attribute will be used.
Public propertyIsolatedDangers
Gets or sets a value indicating whether to display isolated dangers in shallow water.
Public propertyLabelContours
Gets or sets a value indicating whether to display the depth contour labels, including safety contour labels.
Public propertyLabelSafetyContours
Gets or sets a value indicating whether to display the safety contour labels.
Public propertyLowAccuracy
Gets or sets a value indicating whether to use low accuracy symbols (CATZOC).
Public propertyCode examplePointSymbolizationType
Gets or sets the S-52 point feature symbolization type (simplified/paperchart).
Public propertySafetyContour
Gets or sets the depth of the safety contour in meters.
Public propertyShallowContour
Gets or sets the depth of the shallow contour in meters.
Public propertyShowShallowDepthPattern
Gets or sets a value indicating whether the shallow depth pattern will be symbolized.
