Gibco basemap not being visualized

kishorekumar1 · ‎07-18-2018

Dear Sir,

I was using the Gibco basemap with the url: "https://maps.ngdc.noaa.gov/arcgis/rest/services/web_mercator/gebco_2014_hillshade/MapServer" as my basemap in our applciation which is developed using "ArcGIS api for javascript ".But now i am not able to view the basemap. But,when i view the service in arcgis online i am able to view the Gibco basemap.But it is failing using arcgis api for javascript. Can any one help me in this regard

Regards,

Kishore Kumar

You cannot use a dynamic service as a basemap in the map constructor. This code works for tiled services

Take a look at this post for one way to use a dynamic service in the Basemap Gallery

That service also doesn't appear to be showing anything. It's not getting visualized in the AGOL Map Viewer
