Weather Data

CesiumJS
1

Has anyone had any success using Open Weather Maps or any other provider of weather data? It seems like it should be something simple but all I seem to get is a white globe for clouds and none of the other maps work (precipitation_new, wind_new, etc.). Code snippet below.

var imageryLayers = viewer.imageryLayers;
imageryLayers.addImageryProvider(new Cesium.WebMapTileServiceImageryProvider({
url : ‘http://{s}.tile.openweathermap.org/map/clouds_new/{z}/{x}/{y}.png?appid={api_key}’,
layer : ‘Clouds’,
style : ‘default’,
format : ‘image/png’,
tileMatrixSetID : ‘a’,
maximumLevel: 18
}));

If there is something better than OWM, I’m good with that. Any help would be appreciated. Thanks!

I use a WMS feed direct from noaa.gov:

http://idpgis.ncep.noaa.gov/arcgis/services/NWS_Forecasts_Guidance_Warnings/watch_warn_adv/MapServer/WMSServer

That's warnings, not live weather, but there are other services listed at

https://idpgis.ncep.noaa.gov/arcgis/rest/services

I just pulled up the "base reflectivity radar" at http://idpgis.ncep.noaa.gov/arcgis/services/radar/radar_base_reflectivity_time/ImageServer/WMSServer and it looks like what I typically think of as a weather map.

They even set their CORS headers, so you don't need a proxy!

Hey James,

Thanks for the info. Do you have a code snippet you can provide of your usage with NOAA? I haven’t had any luck. Keep getting errors failing to obtain image tiles.

Thanks!

This works for me:

Note that the HTTP version redirects through to HTTPS, but the redirect isn't served with an Access-Control-Allow-Origin header so the browser won't follow it. Maybe that was your issue? All this gets *much* easier when making your requests through a proxy...

I see this is for USA bbox / region. Is there something similar world wide?

  1. I want to show 3D clouds when I tile the globe in a ‘plane’ modus to see the clouds also above the mountains. Did someone do this already?

Hey Geoneer,

There is a cool cloud rendering screenshot we retweeted from @GeoFlightSim. Maybe encourage them to contribute!

Thanks,
