Class S125AtonPortrayalProjection

Namespace

EncDotNet.S100.Datasets.S125

Assembly

EncDotNet.S100.Datasets.S125.dll

Projects S-125 Marine Aids to Navigation features onto the S-101 feature and attribute model so the bundled S-101 Portrayal Catalogue's AtoN rules (buoys, beacons, topmarks, daymarks, landmarks, lights and light sectors, AIS aids, navigation lines and tracks) can portray them.

Remarks

The S-125 Edition 1.0.0 Portrayal Catalogue (PS clause 13 / Annex D) only portrays AtoN status indications and data coverage: S-125 is designed as an overlay on the ENC's own AtoN symbology rather than a replacement for it. Portraying the aids themselves is therefore an implementation choice of this library, made by reusing S-101 symbology — see the S-125 dataset README.

Both feature catalogues draw their AtoN feature types and attributes from the IHO GI Registry, so most features map one-to-one (same type code, same attribute codes and listed values, same sectorCharacteristics / rhythmOfLight complex structure). The remaining differences are bridged here:

• S-125 models topmarks as separate Topmark equipment features bound to their structure by the StructureEquipment association; S-101 carries them as the structure's topmark complex attribute. Each Topmark is lifted onto its parent structure (falling back to a co-located buoy or beacon when no association is encoded).
• SyntheticAISAidToNavigation has no S-101 counterpart and is portrayed as PhysicalAISAidToNavigation (an AIS message broadcast for a physical aid).
• Attribute renames: maximalPermittedDraught → maximumPermittedDraught; the orientation complex flattens to S-101's simple orientationValue where S-101 binds that; and the pre-1.0 draft spellings objectName / MMSICode map to featureName / mMSICode.

Features that S-125 portrays itself (AtonStatusIndication, DataCoverage), geometry-less aggregations, and meta features with no AtoN symbology are not projected.

Methods

MapFeatureType(string, FeatureCatalogue)

The S-101 feature type an S-125 feature type is portrayed as, or null when the type is not portrayed through the S-101 rules.

public static string? MapFeatureType(string s125FeatureType, FeatureCatalogue s101Catalogue)

Parameters

s125FeatureType string

The S-125 feature type code.

s101Catalogue FeatureCatalogue

The S-101 feature catalogue; only its non-abstract types are targets.

Returns

string

Project(S125Dataset, FeatureCatalogue)

Projects the portrayable features of dataset onto the S-101 model.

public static IReadOnlyList<S125ProjectedAton> Project(S125Dataset dataset, FeatureCatalogue s101Catalogue)

Parameters

dataset S125Dataset

The S-125 dataset.

s101Catalogue FeatureCatalogue

The S-101 feature catalogue (target types and attribute bindings).

Returns

IReadOnlyList<S125ProjectedAton>

One entry per portrayable feature, in dataset order.
