I have added the USA Topo maps to the BasemapGallery. Works great in the widget as an option to choose from.
But I want to make the USA Topo maps the default for the web application. I cannot seem to get it to recognize the new layer.
For now, I have set the basemap to be "gray".
Then I make the BasemapGallery.
Then, when the user zooms in, it should change to my new basemap. This code works if I change the basemap to "topo" or one of the other ArcGIS basemaps. But it won't get the usatopo basemap.
In this example, I also add the google maps. I'd be interested in knowing how to select one of the google themes as a basemap.
But first things first, - how do I get the usatopo to be the default? If I make it a tiled layer and add it as a map layer ( as in using map.addLayers([usatopo]) , then it covers the other basemaps, if someone switches to one of those. So it's acting like a layer and not a basemap.
Thank you.
