        - `type GeoJsonGeometryCoordinatesArray [][][]float64`

        - `type GeoJsonGeometryCoordinatesArray [][][][]float64`

      - `Type GeoJsonGeometryType`

        - `const GeoJsonGeometryTypePoint GeoJsonGeometryType = "Point"`

        - `const GeoJsonGeometryTypeLineString GeoJsonGeometryType = "LineString"`

        - `const GeoJsonGeometryTypePolygon GeoJsonGeometryType = "Polygon"`

        - `const GeoJsonGeometryTypeMultiPoint GeoJsonGeometryType = "MultiPoint"`

        - `const GeoJsonGeometryTypeMultiLineString GeoJsonGeometryType = "MultiLineString"`

        - `const GeoJsonGeometryTypeMultiPolygon GeoJsonGeometryType = "MultiPolygon"`

    - `Properties map[string, unknown]`

    - `Type GeoJsonFeatureType`

      - `const GeoJsonFeatureTypeFeature GeoJsonFeatureType = "Feature"`

    - `ID string`

      Feature identifier (type/osm_id)

    - `OsmID int64`

      OpenStreetMap ID

  - `Type FeatureCollectionType`

    - `const FeatureCollectionTypeFeatureCollection FeatureCollectionType = "FeatureCollection"`

    OverpassQuery: githubcomplazafyiplazago.OverpassQueryParam{
      Data: githubcomplazafyiplazago.F("data"),
    },
  })
