Remarks

S-101 tiles every cell with group-1 (skin of the earth) areas: land is a LandArea, and water is a DepthArea, DredgedArea or UnsurveyedArea. Ground that covers and uncovers is a DepthArea whose minimum depth (depthRangeMinimumValue, DRVAL1) is negative, a drying height.

Fields

Coastline

The feature type of an S-101 coastline.

public const string Coastline = "Coastline"

Field Value

string

DepthArea

The feature type of an S-101 depth area.

public const string DepthArea = "DepthArea"

public static SkinOfTheEarthClass Classify(string featureType)

Parameters

featureType string

The S-101 feature type, such as "DepthArea".

Returns

SkinOfTheEarthClass

The class, or None.

IsDrying(string, IReadOnlyDictionary<string, object?>)

Whether a DepthArea dries: its minimum depth (DRVAL1) is below the vertical datum, or, without a minimum, its maximum (DRVAL2) is at or above it.

public static bool IsDrying(string featureType, IReadOnlyDictionary<string, object?> attributes)

Parameters

featureType string

The feature type; anything but a DepthArea never dries.

attributes IReadOnlyDictionary<string, object>

The feature's attributes, keyed by code (S-101 camel case or the S-57 acronym).
