Hi,
I just need to know the weather at a current position.
I have the following script, but it doesn't work.
key = 'MyKey';
op = 'TA2';
z = '1';
x = '51.36';
y = '6.16';
options = weboptions('ContentType','json');
url = ['http://maps.openweathermap.org/maps/2.0/weather/TA2/',z,'/',x,'/',y,'?date=1527811200&opacity=0.9&fill_bound=true&appid=',key];
Current_Data = webread(url, options);
Can anyone tell me what is going wrong here? I got the folowing URL from OpenWeatherMap:
http://maps.openweathermap.org/maps/2.0/weather/{op}/{z}/{x}/{y}?appid={API key}
Thanks in advance

What does it mean by "it doesn't work"? Any error message you saw?
Try the html directly outside matlab and make sure it works first. You can use curl from command line window.

@Dion Theunissen: When you run webread(url) from matlab command line, what error does it shown on the command line window? I tried your example, it shows HTTP status 401, which means unauthorized. This is correct because I don't have an API key. But your url looks good.
