Hello, please read the last item as data1[[All,1]], where data1 comes from the following lines: nedsteden = CityData[{All, "Netherlands"}]; nedstedencoords = {#, CityData[#, "Coordinates"]} & /@ nedsteden ; rr = DeleteCases[nedstedencoords, {{_, _, _}, {_Missing, _Missing}}] ; (* rr is used for checking *) dutchstations = WeatherData[#] & /@ rr[[All, 2]]; data = {#, WeatherData[#, "Temperature"]} & /@ dutchstations; (* data is also used for checking, like rr *) data1 = DeleteCases[data, {_, _Missing}]; (* yes, now I am sure Mathematica gives the right data. It is easy to check the data for the whole of the Netherlands *) So the last code must be: Graphics[{Gray, CountryData["Netherlands", "FullPolygon"], {PointSize[Large], Hue[WeatherData[#, "Temperature"]/30], Tooltip[Point[Reverse[WeatherData[#, "Coordinates"]]], WeatherData[#]]} & /@ data1[[All, 1]]}] Sorry for the mistake. with friendly greetings, P_ter
