anchor.diff:          + hasObservationData: `true` (boolean, optional) - station has observation data.
           + countryIsoCode: `GB` (string, optional) - station located in this country. ISO Code refers to the [ISO 3166 alpha-2 codes](https://en.wikipedia.org/wiki/ISO_3166)
   
  -The API supports various combinations for querying stations data by bounding box, polygon, multi-polygon, by provider and type, by stations that produce forecast and observation data.
  +The API supports various combinations for querying stations data by area/region (bounding box, polygon, multi-polygon), by provider or type,
  +by stations where MeteoGroup produces forecast or has observation data available.
   Here are a couple of examples how to query by provider and type, bounding box and polygon.
   
  -#### Querying by provider and type
  +#### Querying by provider or type
   
   Query example:
   
  
positive.code: ```
  
  If the station data are queried by polygon box, appropriate "type" in **locatedWithin** parameter must be mentioned: **"type":"polygon", "coordinates":{...}**.
  **NOTE**: The **locatedWithin** parameter has to be encoded before putting it to the request. Online URL encoder: http://www.url-encode-decode.com/
  
  #### Get all station types
  
  
negative.code: + Parameters
  
          + locatedWithin:
              - {"type":"bbox","coordinates":[[lon,lat],[lon,lat]]} (string, optional) - top left and bottom right coordinates that construct bounding box
              - {"type":"polygon","coordinates":[[[-10,10],[10,5],[-5,-5],[-10,10]],[[-5,5],[0,5],[0,0],[-5,5]]]} - polygon coordinates; same as in [GeoJSON Polygon](https://tools.ietf.org/html/rfc7946#section-3.1.6)
              - {"type":"multipolygon","coordinates":[[[[102.0,2.0],[103.0,2.0],[103.0,3.0],[102.0,3.0],[102.0,2.0]]],

          + accessVisibility: `public` (string, optional) - station access visibility, valid values is `public` and `private`
          + provider: `WMO,MG` (string, optional) - currently filter by provider or providers. All possible providers are described in section: **Get all providers**
          + type: `SKI_RESORT` (string, optional) - currently filter by type. All possible types are described in section: **Get all station types**
