Implementation Reference

• src/modules/geodata.ts:242-262 (handler)

  The handler implementation for the identify_location tool in src/modules/geodata.ts.

  case "identify_location": {
    const lat = args.lat as number;
    const lng = args.lng as number;
    const extent = `${lng - 0.001},${lat - 0.001},${lng + 0.001},${lat + 0.001}`;
    const layers = args.layers ? `all:${args.layers}` : "all";
    const url = buildUrl(`${BASE}/rest/services/all/MapServer/identify`, {
      geometry: `${lng},${lat}`,
      geometryType: "esriGeometryPoint",
      layers,
      mapExtent: extent,
      imageDisplay: "500,500,96",
      tolerance: 5,
      sr: 4326,
      returnGeometry: false,
    });
    const data = await fetchJSON<IdentifyResponse>(url);
    return JSON.stringify({
      count: data.results.length,
      results: data.results.slice(0, 20).map(slimIdentifyResult),
    });
  }

• src/modules/geodata.ts:139-150 (schema)

  The tool registration and input schema for identify_location.

    name: "identify_location",
    description: "Identify geographic features and data layers at a specific Swiss location",
    inputSchema: {
      type: "object",
      required: ["lat", "lng"],
      properties: {
        lat: { type: "number", description: "Latitude (WGS84)" },
        lng: { type: "number", description: "Longitude (WGS84)" },
        layers: { type: "string", description: "Comma-separated layer ids (default: all visible)" },
      },
    },
  },
