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: required scope is `station-metadata`.
