Ocean Basemap Issue

EricLake — Fri, 24 Jun 2011 14:14:20 GMT

Since the new Ocean Basemap was added, i have noticed that if it is the default basemap loaded, the zoom levels of the map are then restricted no matter what layer is chosen after that.

like in this sample.

Is there are quick way around if using the thumbnail picker widget?

Thanks

One approach to workaround this issue is to add a basemap with more zoom levels before creating the basemap gallery. In this snippet the World Topo Map is added so the map will be initialized with more levels:

   var initBasemap = new esri.layers.ArcGISTiledMapServiceLayer("http://server.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer");
        map.addLayer(initBasemap);
        
        createBasemapGallery();
