name: kystverket
description: Query Norwegian maritime infrastructure data from Kystverket via WFS. Use this skill ALWAYS when the user asks about maritime speed limits (fartsgrenser sjø), pilot stations (losstasjoner), fairways (farleder), anchorage areas (ankringsområder), emergency harbors (nødhavner), fishing harbors (fiskerihavner), vessel traffic service areas (VTS), pilotage boarding areas (losbordingsfelt), ISPS port facilities, maritime traffic separation schemes, or coastal infrastructure in Norway. Also trigger when user mentions Kystverket, losplikt, farled, havneanlegg, or Norwegian maritime regulations.

## Query features

```bash
curl -s "https://services.kystverket.no/wfs.ashx?service=WFS&version=1.1.0&request=GetFeature&typeName={LAYER_ID}&maxFeatures=5&srsName=EPSG:4326"
```

**Parameters:**
- `service=WFS&version=1.1.0&request=GetFeature` (required)
- `typeName` — layer ID from table above
- `maxFeatures` — limit results
- `srsName=EPSG:4326` — return WGS84 coordinates (recommended)
- `bbox=minlat,minlon,maxlat,maxlon,EPSG:4326` — spatial filter

**Note:** JSON output is not supported. Responses are GML/XML.

### Example response structure (pilot stations)

```xml
<ms:layer_59>
  <ms:msGeometry>
    <gml:Point srsName="EPSG:4326">
      <gml:pos>{LAT} {LON}</gml:pos>
    </gml:Point>
  </ms:msGeometry>
  <ms:navn>...</ms:navn>
  <ms:funksjon>Losstasjon</ms:funksjon>
  <ms:losavdeling>...</ms:losavdeling>
</ms:layer_59>
```

### Speed limits in a bbox

```bash
curl -s "https://services.kystverket.no/wfs.ashx?service=WFS&version=1.1.0&request=GetFeature&typeName=layer_754&maxFeatures=10&srsName=EPSG:4326&bbox={MINLAT},{MINLON},{MAXLAT},{MAXLON},EPSG:4326"
```

## Capabilities & layer discovery

```bash
curl -s "https://services.kystverket.no/wfs.ashx?service=WFS&request=GetCapabilities"
```

Lists all available layers with bounding boxes and abstracts.

## Common recipes

```bash
# All pilot stations in Norway
?service=WFS&version=1.1.0&request=GetFeature&typeName=layer_59&srsName=EPSG:4326

# Emergency harbors
?service=WFS&version=1.1.0&request=GetFeature&typeName=layer_26&srsName=EPSG:4326

# Speed limits for recreational vessels in a bbox
?service=WFS&version=1.1.0&request=GetFeature&typeName=layer_754&maxFeatures=50&srsName=EPSG:4326&bbox={MINLAT},{MINLON},{MAXLAT},{MAXLON},EPSG:4326

# ISPS port facilities
?service=WFS&version=1.1.0&request=GetFeature&typeName=layer_420&srsName=EPSG:4326

# Fishing harbors
?service=WFS&version=1.1.0&request=GetFeature&typeName=layer_1077&srsName=EPSG:4326
```

## Notes

- Speed limit layers `layer_754` and `layer_762` are the comprehensive ones — they combine national regulations and local ordinances.
- `layer_722`/`layer_723` contain only national (statlige) speed limits under the Harbour Act.
- The `Slukkinger` layer (extinguished lights) updates every night at 02:00.
- All coordinate queries use lat/lon order in WFS 1.1.0 bbox (not lon/lat).
