New to Node-RED and am tooling around with the WorldMap Node. I'm interested to see if I can overlay this map service: [https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/radar\_meteo\_imagery\_nexrad\_time/MapServer](https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/radar_meteo_imagery_nexrad_time/MapServer)

This is my logic, I get no errors but also no map.

msg.payload = {};  
msg.payload.command = {};

var mURL = "[https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/radar\_meteo\_imagery\_nexrad\_time/MapServer](https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/radar_meteo_imagery_nexrad_time/MapServer)";

msg.payload.command.map = {overlay:"Weather", url:mURL, layer:"Weather"};

return msg;

If this is not the right forum I apologize in advanced,

Thanks

Steve

Hi,  
well you have just tried to point at a web page of text so it's not going to show a map ... you need to find the actual WMS map server that that page is talking about. - This requires a bit of digging with things like QGIS etc...

However - testing it for you... - has found a small bug in the overlay naming - so you'll also need to pull latest 1.4.5 version of the worldmap node from npm.

```auto
msg.payload = {};
msg.payload.command = {};

msg.payload.command.map = {
    overlay: "NowCoast",
    url: 'https://nowcoast.noaa.gov/arcgis/services/nowcoast/radar_meteo_imagery_nexrad_time/MapServer/WmsServer?',
    opt: {
        layers: '1',
        format: 'image/png',
        transparent: true,
        attribution: "NOAA/NWS"
    },
    wms: true
}

return msg;

```

looks good though ! (IMHO)

Perfect, thanks! I updated to the latest worldmap version and replaced my logic with yours.

Works like a charm.

Thanks

@smulberry care to share the flow, I'd love to see the specifics.

somewhat trivial ...
