Class S57ProductSpecification

Namespace

EncDotNet.S100.Datasets.S57

Assembly

EncDotNet.S100.Datasets.S57.dll

Codes an S-57 dataset declares in the product specification (PRSP) subfield of its Data Set Identification (DSID) field, which names the product specification the exchange was produced under (S-57 Edition 3.1, Part 1 §1.4.1 and Part 3 §7.3.1.1).

Remarks

S-57 itself enumerates only ElectronicNavigationalChart and ObjectCatalogueDataDictionary. Inland ENC (IENC) producers declare InlandElectronicNavigationalChart: USACE cells built to the IENC 2.4 Product Specification carry PRSP = 10 with a product specification edition (PRED) of 2.4, where a maritime ENC carries PRSP = 1.

The distinction matters because an inland cell is encoded exactly like a maritime one — same ISO 8211 records, same S-57 data model — yet draws on an inland object catalogue (object classes and attributes in the 17000+ code range) whose natural S-100 successor is S-401 rather than S-101.

Fields

ElectronicNavigationalChart

Electronic Navigational Chart (S-57 Appendix B.1).

public const int ElectronicNavigationalChart = 1

Field Value

int

InlandElectronicNavigationalChart

Inland Electronic Navigational Chart, as declared by IENC producers. Not enumerated by S-57 Edition 3.1 itself.

public const int InlandElectronicNavigationalChart = 10

Field Value

int

ObjectCatalogueDataDictionary

IHO Object Catalogue Data Dictionary (S-57 Appendix B.2).

public const int ObjectCatalogueDataDictionary = 2

Field Value

int

Methods

TryParse(string?, out int)

Parses a PRSP subfield value as read from a dataset. ENCs use the binary implementation, where the subfield is a one-byte integer (b11) that reads back as its decimal digits. The ASCII implementation's acronym form (ENC, ODD) is not recognised.

public static bool TryParse(string? value, out int code)

Parameters

value string

The raw subfield value, e.g. "10".

code int

The parsed product specification code.

Returns

bool

true when value is a non-negative integer.
