# STN013411 / STN013411_plus - overview and provenance

releaseId: `20260919-v35`
knowledgeVersion: `2026.09.19-v35`
branch: `64`
track: `stn013411-symbology`

## What this resource set is

`STN013411` and `STN013411_plus` are MicroStation resource libraries used in the GRAPHICO/iNGs ecosystem for large-scale map symbology derived from **STN 01 3411 Mapy veľkých mierok** and extended with additional practical symbols outside the standard.

The current public iNGs product page describes `iNGs_STN013411_plus` as containing all point symbols (cells) and line symbols (custom line styles) defined by STN 01 3411 plus symbols beyond the standard. It also identifies the four delivered resource files:

- `STN013411.cel` - cells in the STN 01 3411 part,
- `STN013411.rsc` - line styles in the STN 01 3411 part,
- `STN013411_plus.cel` - additional cells beyond STN 01 3411,
- `STN013411_plus.rsc` - additional line styles beyond STN 01 3411.

The visual catalogue is published at:

`https://www.ings.sk/wp-content/uploads/iNGs_STN013411_plus.pdf`

The available PDF identifies itself as **version 5.0, February 2012**. It is therefore used as a semantic/visual baseline, not as proof that its inventory is the newest complete inventory.

## Provenance history relevant to the KB

Maintainer evidence supplied to GRAPHICO records that the original MicroStation implementation dates to **1995** and was later jointly maintained/extended in the GRAPHICO/iNGs environment. The `plus` name is intentional: later resources include practical symbols that the STN itself does not define.

Do not collapse these provenance layers:

1. **STN 01 3411** - normative semantic origin of standard symbols.
2. **STN013411** - MicroStation implementation of the standard-oriented resource set.
3. **STN013411_plus** - maintained practical extension beyond the standard.
4. **MSet usage** - how a concrete MSet instruction chooses and activates those resources.

A `plus` resource must never be presented as if STN 01 3411 itself defined it.

## Current resource snapshot supplied for KB intake

GRAPHICO supplied a current four-file resource snapshot for this intake. Archive metadata / file inspection gives:

| Resource | Size | Snapshot timestamp | SHA-256 |
| --- | ---: | --- | --- |
| `STN013411.cel` | 476672 B | 2025-06-23 08:34 | `65D466A0D847E2C8011DBB61F629C0137164ED4BAD29A8BC960F1FD32CE32AE1` |
| `STN013411.rsc` | 152808 B | 2021-04-02 18:55 | `85642CE04CB05DCE1E7FDF248243B78744F5278FB2AFA12B18EB0C3D4F46B73D` |
| `STN013411_plus.cel` | 258048 B | 2025-06-23 08:53 | `B3A0D715DA045DDF8641983C274D97749399B3CE4595D0069A157B2F1DB957B` |
| `STN013411_plus.rsc` | 64240 B | 2019-07-21 21:12 | `0E37F61B69E8CBDAD96BCA60EBF4801ED4479F6858169C7E00E37865C6E7EDAF` |

The two CEL files report MicroStation as the creating application and were last saved on 2025-06-23. This is evidence that the physical libraries are newer than the 2012 PDF.

Maintainer evidence for this intake says that already defined resources were not redefined incompatibly; later changes were additions. The PDF can therefore be used as a stable semantic baseline for entries that it contains, while the current CEL/RSC snapshot remains stronger evidence for the present resource files themselves.

## Scope of this track

This track explains:

- the STN versus `plus` boundary,
- the `L` / `G` / `B` resource model,
- naming conventions,
- how MSet instructions normally use the shared set,
- precedence of project-specific symbology,
- evidence and licensing boundaries.

It is not a substitute for the full STN standard or the complete visual catalogue.
